1. Be sure the engine Stop control is pushed in.2.Turn the Start / Preheat switch to the Preheat position (Turn Counter Clockwise). Above 5oC (41oF) preheat for 5 seconds. Below 5oC (41oF) preheat for 15 seconds. (This will heat the glow plugs and the engine combustion chambers.)3. To crank and start the engine turn Start / Preheat switch (clockwise) to the start position. Release the switch when engine starts.4. If the engine does not start within 15 seconds, release the switch and repeat steps 2 and 3

The Mariner 5+3 is a 400 amp @ 60% duty cycle, constant current, DC diesel engine-driven welder with 3,000 watts 120 VACauxiliary power. Its copper wound “pure DC” generator provides excellent welding characteristics and has enough power forgouging with up to 3/16" carbons. Output adjustment is via dual continuous output controls and the polarity of the outputterminals is selected via a two-position polarity switch. Fine current control can be adjusted remotely by connecting a rheostat-type remote control to the standard remote control receptacle. A specially-built protective enclosure minimizes saltwater intrusion and incorporates a built-in drip pan/reservoir to contain fluids in the event of an engine-oil or -coolant leak, aswell as easy-opening access panels for convenient equipment operation and maintenance. Welding generator enhancementsinclude modifications such as stainless steel brush holders for enhanced corrosion resistance in harsh environments.
