The M-400 Welding System is CRC-Evans’ lightweight,multi-process, multi-power source, on-board wirefeed, single torch welding system.

The M-400 bug retains all the range and functionalityof its predecessor while reducing overall weight by25%. In addition to multifunctionality and decreasedweight, the M-400’s new offset oscillator offers itsoperator an unprecedented view of the arc as welladding the ability to deposit automated fillet (+45 /- 30deg) welds. Lastly, our engineers have built softwaretracking into the welding parameters allowing itsoperator to recall exactly what versions of softwarewere being used for each weld. The M-400 WeldingSystem is revolutionary on every front.

The M-400 system is multi-process and multi-weldingpower supply capable. It can be adapted to weld flux

core, inner-shield, STT and GMAW with minimalmechanical changes to the bug. Complimenting itsability for multi-process welding, the M-400 allows theflexibility of utilizing digital or analog welding powersources.

The M-400 system offers CRC’s cutting edge Thru-

The-Arc-Tracking. This advanced technology maintains

the optimum tip to work distance ensuring consistent

high-quality welds with minimum effort.

The revolutionary redesigned pendant includes a

large format, color display. The pendant not only

operates the M-400 system, but its display relays

multiple levels of information and allows the

adjustment of parameters without the need to plug in

a laptop or PDA.

Electrical and Temperature Specifications

Welding Power Supplies Supported

Thru the arc vertical tracking maintains the torch at aconstant stick out distance.

Tracking can be performed with either with Volts, Amps, or Impedance (Process independent)

Position based welding allows real-time weld parameterchanges via a 3 axis accelerometer.

Feedback from optical encoders on Travel and Wire Feedmotors removes the need for motor calibration.

Easy to use graphical user interface allows for easy editingof welding parameters.

Limits enforced on most programmable weldingparameters.

Closed loop PID control available to precisely control arcvoltage on analog power sources.

Programmable potentiometer can be set to control wirefeed speed, travel speed, target volts/amps, etc.
