7Installation and Operator Instructions

Read this entire section before installation or operationof the machine.

Location and EnvironmentThis machine will operate in harsh environments.However, it is important that simple preventativemeasures are followed to assure long life and reliableoperation.

Do not place or operate this machine on a surfacewith an incline greater than 15 from horizontal.

This machine must be located where there is freecirculation of clean air without restrictions for airmovement to and from the air vents. Do not coverthe machine with paper, cloth or rags when switchedon.

Dirt and dust that can be drawn into the machineshould be kept to a minimum.

This machine has a protection rating of IP23. Keepit dry when possible and do not place it on wetground or in puddles.

Locate the machine away from radio controlledmachinery. Normal operation may adversely affectthe operation of nearby radio controlled machinery,which may result in injury or equipment damage.Read the section on electromagnetic compatibility inthis manual.

Do not operate in areas with an ambient temperaturegreater than 40C.

Input Supply ConnectionCheck the input voltage, phase, and frequency suppliedto this machine before turning it on. The allowable inputvoltage is indicated in the technical specification sectionof this manual and on the rating plate of the machine.Verify the connection of grounding wires from themachine to the input source.

Make sure the amount of power available from the inputconnection is adequate for normal operation of themachine. The necessary fuse and cable sizes areindicated in the technical specification section of thismanual.

This machine is designed to operate on engine drivengenerators as long as the 230Vac auxiliary can supplyadequate power as indicated in the technicalspecification section of this manual. The auxiliarysupply of the generator must also meet the followingconditions.

The AC waveform peak voltage is below 410V. The AC waveform frequency is between 50 and 60

hertz. The RMS voltage of the AC waveform is always

equal to 230Vac 10%.

It is important to check these conditions because manyengine driven generators produce high voltage spikes.Operation of this machine on engine driven generatorsnot conforming to these conditions is not recommendedand may damage the machine.

Output ConnectionsA quick disconnect system using Twist-MateTM cableplugs is used for the welding cable connections. Refer tothe following sections for more information onconnecting the machine for operation of stick welding(MMA) or TIG welding (GTAW).

Stick Welding (MMA)First determine the proper electrode polarity for theelectrode to be used. Consult the electrode data for thisinformation. Then connect the output cables to theoutput terminals of the machine for the selected polarity.For example, if DC(+) welding will be used then connectthe electrode cable to the (+) terminal of the machine andthe work clamp to the (-) terminal. Insert the connectorwith the key lining up with the keyway and rotateapproximately turn clockwise. Do not over tighten.

For DC(-) welding switch the cable connections at themachine so that the electrode cable is connected to (-)and the work clamp is connected to (+).

TIG Welding (GTAW)This machine does not include a TIG torch necessary forTIG welding, but one may be purchased separately.Refer to the accessories section for more information.Most TIG welding is done with DC(-) polarity; connectthe torch cable to the (-) terminal of the machine and thework clamp to the (+) terminal. Insert the connectorwith the key lining up with the keyway and rotateapproximately turn clockwise. Do not over tighten.

For V160-S machines, connect the gas hose from theTIG torch to a gas regulator on the cylinder of gas to beused.

For V160-T machines, connect the gas hose from theTIG torch to the gas connector (B) on the front of themachine. If necessary, an extra gas connector for thefitting on the front of the machine is included in thepackage. Next, connect the fitting on the back of themachine to a gas regulator on the cylinder of gas to beused. An input gas line and the required fittings are alsoincluded in the package. Connect the TIG torch triggerto the trigger connector (A) on the front of the machine.

Remote Control ConnectionFor V160-T machines only, refer to the accessoriessection for a list of remote controls. If a remote controlis used, it will be connected to the remote connector (C)on the front of the machine. The machine willautomatically detect the remote control, turn on the

8REMOTE LED, and switch to remote control mode.More information on this mode of operation will begiven in the next section.

Controls and Operational FeaturesA. Power Switch: Controls the input power to the

machine. Make sure the machine is properlyconnected to the input supply before turning themachine on.

B. Fan: The cooling fan will turn ON when themachine is turned ON and it will continue to runwhenever the output of the machine is ON. If theoutput of the machine is OFF for more than fiveminutes, the fan will turn OFF. This reduces theamount of dirt that is deposited inside the machineand reduces power consumption.

Refer to the Output LED section below for moreinformation about conditions when the output of themachine is ON. The V160-S always has the outputturned ON so the fan will not turn OFF.Additionally, when the V160-T machines are in Stickmode, the fan will not turn OFF because the outputremains ON.

C. Gas Inlet (V160-T machines only): Connector forthe TIG shielding gas. Use the supplied gas line andconnector to connect the machine to the gas source.The gas source must have a pressure regulator andflow gage installed.

D. Mode Switch: This switch changes the weldingmodes of the machine. The V160-S has twowelding modes: Stick (SMAW) and Lift TIG(GTAW). The V160-T machines have threewelding modes: Stick (SMAW), Lift TIG (GTAW)and HF TIG (GTAW).

When the mode switch is in the Stick position, thefollowing welding features are enabled.

Hot Start: This is a temporary increase in the outputcurrent during the start of the stick welding process.This helps ignite the arc quickly and reliably.

Arc Force: This is a temporary increase in theoutput current during normal stick welding. Thistemporary increase in output current is used to clearintermittent connections between the electrode andthe weld puddle that occur during normal stickwelding. The amount of arc force can be adjustedon the V160-S, refer to Arc Control, describedbelow.

Anti-Sticking: This is a function which decreasesthe output current of the machine to a low levelwhen the operator makes an error and sticks theelectrode to the work piece. This decrease in currentallows the operator to remove the electrode from theelectrode holder without creating large sparks whichcan damage the electrode holder.

When the mode switch is in the Lift TIG position, thestick welding functions are disabled and the machine

is ready for Lift TIG welding. Lift TIG is a methodof starting a TIG weld by first pressing the TIG torchelectrode on the work piece in order to create a lowcurrent short circuit. Then, the electrode is liftedfrom the work piece to start the TIG arc.

The last mode switch position, HF TIG, is onlyavailable on the V160-T machines. When the modeswitch is in this position, the stick welding functionsare disabled and the machine is ready for HF TIGwelding. During the HF TIG mode, the TIG arc isstarted by HF without pressing the electrode on thework piece. The HF used for starting the TIG arcwill remain on for 6.5 seconds; if the arc is notstarted in this time limit, the trigger sequence must berestarted.

E. Trigger Mode Switch (V160-T machines only):This switch changes between 2-step and 4-steptrigger sequences. For an explanation of thesetrigger sequences refer to the trigger sequencesexplained below.

F. Power LED: This indicator will blink on and offwhen the machine is first turned on. Afterapproximately 2 seconds it will stop blinking andremain on to signal that the machine is ready.

G. Thermal LED: This indicator will turn on when themachine is overheated and the output has beendisabled. This normally occurs when the duty cycleof the machine has been exceeded. Leave themachine on to allow the internal components tocool. When the indicator turns off, normaloperation is again possible.

H. Remote LED (V160-T machines only): Thisindicator will turn on when a remote control isconnected to the machine via the remote controlconnector. Using a remote control will change thefunction of the output current control, refer to theoutput current control section below.

I. Output LED: This indicator turns on when theoutput of the machine is on. Both the type ofmachine and the position of the mode switchdetermine when the output of the machine is turnedon.

V160-S: In both welding modes, selected by themode switch, the output of the machine is alwaysturned on.

V160-T: In stick welding mode, the output of themachine is automatically turned on. However, inboth of the TIG welding modes, the output of themachine is turned ON and OFF by the TIG torchconnected to the trigger connector on the front of themachine.

9J. Arc Control (V160-S only): In stick welding mode,this controls the amount of current used during arcforce. In TIG welding mode, this is not used.

K. Output Current Control: This controls the output, orwelding, current of the machine.

For V160-T machines, the function of this controlknob is changed if a remote control is connected. Ifthe Remote LED is ON, this indicates that a remotecontrol is connected and the function of the outputcurrent control will be:

Stick Welding Mode: The remote control willadjust the output current of the machine from 5 to160A. The output current control knob on thedisplay panel is not used.

TIG Welding Modes: The maximum output currentof the machine is set by the output current controlknob. Then the remote control adjusts the outputcurrent from the minimum output (5A) to the valueset by the output current control knob. For example,if the output current control knob on the machine isset to 100A then the remote control will adjust theoutput current from a minimum of 5A to a maximumof 100A.

L. Downslope Control (V160-T machines only): In theTIG welding modes, this control knob will adjustthe downslope time from 0.5 to 20 seconds. (Theupslope time is always 0.5 seconds.) Refer to thetrigger sequence section below to understand howdownslope is activated. In Stick welding mode, thisis not used.

M. Postflow Control (V160-T machines only): In theTIG welding modes, this control knob will adjustthe shielding gas postflow time from 0.5 to 30seconds. (The preflow time is always 0.5 seconds.)In Stick welding mode, this is not used.

N. Meter (V160-T Pulse only): This meter displays thepreset welding current before welding and the actualwelding current during welding. Like the outputcurrent control, the function of the meter is changedif a remote control is connected. If the Remote LEDis ON, this indicates that a remote control isconnected and the meter will display the followinginformation before welding (during welding, themeter always displays the actual welding current):

Stick Welding Mode: The meter displays the presetwelding current but this is adjusted from the remotecontrol as explained in the Output Current Controlsection.

TIG Welding Modes: The meter displays themaximum output current which is set by the outputcurrent control knob. The preset welding current isthen adjusted by the remote control, but it is notdisplayed on the meter.

O. Pulsing Mode Switch (V160-T Pulse only): In theTIG welding modes, this switch turns the pulsingfunction ON and controls the pulsing frequencyrange (20Hz or 300Hz). In Stick welding mode, thisis not used.

P. Pulsing LED (V160-T Pulse only): This indicatorshows the pulsing frequency when pulsing is turnedON. With this indication, the operator can adjustthe frequency to the desired value before welding.(Note: At higher frequencies the LED blinks veryfast and seems to be continuously ON however it ispulsing.) If pulsing is turned OFF or if the machineis in Stick welding mode, the indicator will be OFF.

Q. Pulsing Frequency Control (V160-T Pulse only):When the pulsing function is ON, this control knobwill adjust the pulsing frequency. The pulsingfrequency adjustment range is 0.2 - 20Hz or 3 -300Hz depending on the Pulsing Mode Switchposition.

R. Pulsing Background Current Control (V160-T Pulseonly): When the pulsing function is ON, thiscontrol knob will adjust the pulsing backgroundcurrent. This is the current during the low portion ofthe pulse waveform; it can be adjusted from 10% to90% of the welding current.

TIG Trigger SequencesFor V160-T machines only, TIG welding can be done ineither the 2-step or 4-step mode which is selected withthe Trigger Mode switch. The specific sequences ofoperation for these two trigger modes are explainedbelow.

In these sequences, the Start/Crater current will be used.This current is 20% of the welding current. Forexample, if the welding current is 100A, the Start/Cratercurrent will be 20A. (If necessary, other values of theStart/Crater current are possible; contact your LincolnElectric sales representative for more information.)

2-Step TIG SequenceWith the Trigger Mode switch in the 2-step position, anda TIG welding mode selected, the following weldingsequence will occur. To setup the machine for TIGwelding refer to the Output Connections section.

1. Press and hold the TIG torch trigger to start thesequence.

The machine will open the gas valve to start theflow of the shielding gas. After a 0.5 secondpreflow time, to purge air from the torch hose, theoutput of the machine is turned ON. At this time thearc is started according to the selected welding mode(Lift TIG or HF TIG). For more information on theLift or HF TIG starting methods, refer to the Modeswitch section above.

10

After the arc is started the output current will beincreased to the welding current. This increase, orupslope, of the output current takes 0.5 seconds tocomplete.

2. Release the TIG torch trigger to stop welding.

The machine will now decrease the output current ata controlled rate, or downslope time, until theStart/Crater current is reached and the output of themachine is turned OFF. The downslope time isadjusted by the Downslope Control knob.

After the arc is turned OFF, the gas valve willremain open to continue the flow of the shieldinggas to the hot electrode and work piece. Theduration of this postflow shielding gas is adjusted bythe Postflow Control knob.

Possible variations of this standard sequence are shownbelow. (If necessary, other variations are also available;contact your Lincoln Electric sales representative formore information.)

As shown above, it is possible to press and hold the TIGtorch trigger a second time during downslope to end thedownslope time and maintain the output current at theStart/Crater current. When the TIG torch trigger isreleased the output will turn OFF and the postflow timewill start.

4-Step SequenceWith the Trigger Mode switch in the 4-step position, anda TIG welding mode selected, the following weldingsequence will occur. To setup the machine for TIGwelding refer to the Output Connections section.

1. Press and hold the TIG torch trigger to start thesequence.

The machine will open the gas valve to start theflow of the shielding gas. After a 0.5 secondpreflow time, to purge air from the torch hose, theoutput of the machine is turned ON. At this time thearc is started according to the selected welding mode(Lift TIG or HF TIG). For more information on theLift or HF TIG starting methods, refer to the Modeswitch section above.

After the arc is started the output current will be atthe Start/Crater current. This condition can bemaintained as long or as short as necessary.

If the Start/Crater current is not necessary, do nothold the TIG torch trigger as described at thebeginning of this step. Instead, quickly press andrelease it. In this condition, the machine willautomatically pass from Step 1 to Step 2 when thearc is started.

2. Release the TIG torch trigger to start the main partof the weld.

The output current will be increased to the weldingcurrent. This increase, or upslope, of the outputcurrent takes 0.5 seconds to complete.

3. Press and hold the TIG torch trigger when the mainpart of the weld is complete.

The machine will now decrease the output current ata controlled rate, or downslope time, until theStart/Crater current is reached. The downslope timeis adjusted by the Downslope Control knob. ThisStart/Crater current can be maintained as long or asshort as necessary.

This sequence has an automatic restart so weldingwill continue after this step. If the weld iscompletely finished, use the following sequenceinstead of step 3 described above.

3A. Quickly press and release the TIG torchtrigger.

The machine will now decrease the outputcurrent at a controlled rate, or downslope time,until the Start/Crater current is reached and theoutput of the machine is turned OFF. After thearc is turned OFF the postflow time will start.

4. Release the TIG torch trigger.

The output current will again increase to the weldingcurrent, like in step 2, to continue welding. Whenthe main part of the weld is complete go to step 3.

Possible variations of this standard sequence are shownbelow. (If necessary, other variations are also available;contact your Lincoln Electric sales representative formore information.)

As shown here, after the TIG torch trigger is quicklypressed and released from step 3A, it is possible to pressand hold the TIG torch trigger another time to end thedownslope time and maintain the output current at theStart/Crater current. When the TIG torch trigger isreleased the output will again increase to the weldingcurrent, like in step 4, to continue welding. When themain part of the weld is complete go to step 3.

As shown here, again after the TIG torch trigger isquickly pressed and released from step 3A, it is possibleto quickly press and release the TIG torch trigger asecond time to end the downslope time and stop welding.

Input Line Voltage, Auxiliary Voltage and Precharge

GENERAL DESCRIPTION

The Invertec V160 series is an inverter based weldingpower sources that offers Tig and Stick process.Depending of the type of the power sources ( V160S,V160T or V160TP ) the machine has differentfunctions:V160S: Is a Stick machine and lift TigV160T: Is a Stick and Tig machine with HFV160TP: Is a Stick and Tig pulser machine with HF

INPUT LINE VOLTAGE, AUXILIARYVOLTAGE AND PRECHARGE

The Invertec V160 can be connected to a 230 single-phase input voltage.The initial power is applied to the Invertec V160trough to a line switch ( S1 ) located on the back of themachine and after it goes to the RFI filter that islocated on the input board.The voltage is after rectified by the input rectifier andthe resultant DC voltage is applied filtered by the filtercapacitors.During the precharge time the DC input voltage isapplied to the filter capacitors through a start resistancethat limits the current. After this time the start relays goclosed and it by-pass the start resistance( there are twostart relays in parallel ).The filtered DC voltage is also applied : to a switching circuit, that gives the necessary low

voltage for the logic circuit, fan and gas solenoid to the HF circuit ( V160T /TP only )

17

Inverter board , Main transformer, Output rectifier and Choke

INVERTER BOARD , MAIN TRANSFORMER,OUTPUT RECTIFIER AND CHOKE

When the input capacitors are fully charged they act aspower supplies for the IGBT switching circuit.The IGBTs supply the main transformer winding with80KHz current flow.The inverter board also monitors the filter capacitorsfor overvoltage. If this occurs, the appropriate signal issent to the control board to disable the machines outputand to turn on the thermal/voltage Overload LED.A pair of IGBTs act as a switch assembly. Thisassembly feeds the primary winding of the maintransformer. When current is pulsed through thisprimary winding, a resultant current is produced on asecondary winding of the main transformer. The DCcurrent flow through the primary winding is redirectedback to the filter capacitors when the IGBTs are turnedoff. This is due to the inductance of the transformerprimary winding.The secondary winding supplies the electrode-to-workvoltages and the resulting current.The output current is regulated via Pulse WidthModulation.The control circuitry, on the inverter board , receives asignal from the control board and regulates the outputcurrent to the desired level.

The output rectifier receives the AC output from themain transformer secondary winding and rectifies it toa DC voltage level. Since the output choke is in serieswith the positive leg of the output rectifier.A filtered DC output is applied to the machines outputterminals.

18

Control board

CONTROL BOARD

The control board receives status and analog feedbackfrom the inverter board, input board and varioussensor. The control circuitry interprets these signals,makes decisions and changes the machine mode andoutput to satisfy the requirements as defined by thecircuitry. The control board sends a signal to theinverter board to control the output current. The controlboard is composed in three parts:- Display board- Weld controller- Meter Board ( only for V160TP )

There are 3 status indicators for the V160S and four forthe V160T and TP:- Power On- Thermal Overload- Output Voltage On- Remote LED On ( only V160T/TP )

19

OVERLOAD PROTECTION

The Invertec V160 is electrically protected fromproducing higher than normal output currents. Anelectronic protection circuit limits the current to withinthe capabilities of the machine.

THERMAL PROTECTION

One thermal device, located on the output heatsink,protect the machine from excessive operatingtemperatures.Excessive temperatures may be caused by a lack ofcooling air or by operating the machine beyond theduty cycle and output rating. If excessive operatingtemperatures should occur,the thermal status indicatorwill turn ON and the thermostat will prevent outputcurrent.

The thermal protection device is self-resetting once themachine cools sufficiently. If the shut down wascaused by excessive output or duty cycle and the fan isoperating normally, the power switch may be left onand the reset should occur within about 15 minuteperiod. If the fan is not turning or the air intake louversare obstructed, the input power must be removed andthe fan problem or air obstruction must be corrected.

20

INSULATED GATE BIPOLARTRANSISTOR (IGBT) OPERATION

An IGBT is a type of transistor. IGBTs are semicon-ductors well suited for high frequency switching andhigh current applications.Drawing A shows an IGBT in a passive mode. Thereis no gate signal, zero volts relative to the source, andtherefore, no current flow. The drain terminal of theIGBT may be connected to a voltage supply; but sincethere is no conduction the circuit will not supplycurrent to components connected to the source. Thecircuit is turned off like a light switch in the OFFposition.

Drawing B shows the IGBT in an active mode. Whenthe gate signal, a positive DC voltage relative to thesource, is applied to the gate terminal of the IGBT, itis capable of conducting current. A voltage supplyconnected to the drain terminal will allow the IGBT toconduct and supply current to circuit componentscoupled to the source. Current will flow through theconducting IGBT to downstream components as longas the positive gate signal is present. This is similarto turning ON a light switch

WARNING






Sometimes machine failures appear to be due to PCboard failures. These problems can sometimes betraced to poor electrical connections. To avoid prob-lems when troubleshooting and replacing PC boards,please use the following procedure:1. Determine to the best of your technical ability that

the PC board is the most likely component caus-ing the failure symptom.

2. Check for loose connections at the PC board toassure that the PC board is properly connected.

3. If the problem persists, replace the suspect PCboard using standard practices to avoid staticelectrical damage and electrical shock.

4. Test the machine to determine if the failure symp-tom has been corrected by the replacement PCboard.

NOTE: Allow the machine to heat up so that allelectrical components can reach theiroperating temperature.

5. Remove the replacement PC board and substituteit with the original PC board to recreate theoriginal problem.

If the original problem does not reappearby substituting the original board, then thePC board was not the problem. Continueto look for bad connections in the controlwiring harness, junction blocks, andtermi-nal strips.

If the original problem is recreated by thesubstitution of the original board, then thePC board was the problem. Reinstall thereplacement PC board and test themachine.

6. Always indicate that this procedure was followedwhen warranty reports are to be submitted.

NOTE: Following this procedure and writing on thewarranty report, INSTALLED AND SWITCHED PCBOARDS TO VERIFY PROBLEM, will help avoiddenial of legitimate PC board warranty claims.
