Ref. ST-187 602-A

1 DC Polarity/AC Switch

YDo not switch under load.

Use switch to select AC weld output or polarity of DC weld output.

2 Process Select Switch

YDo not switch under load.

Use switch to select output for weld process.

3 A/V Control

Use control to select weld voltage or amperage. Control may be adjusted while welding.

4Engine Hour Meter

5High Engine Temperature Light

Light goes on and engine stops if engine tem- perature is too high.

YDo not run engine until trouble is fixed.

6 Low Oil Pressure Light

Light goes on and engine stops if engine oil pressure is too low.

YDo not run engine until trouble is fixed.

7 Glow Plug Switch

If necessary, push switch up before start-up (see table above).

YDo not use glow plugs longer than 20 seconds.

8 Engine Control Switch

Use switch to start engine, select speed, and stop engine. In Run/Idle position, engine runs at idle speed at no load, and weld/power speed under load. In Run position, engine runs at weld/power speed.

.Place switch in Run position to operate most GMAW equipment.

9 Idle Lock Switch

Use switch to lock engine in idle speed during start-up. In Start position and Engine Control switch in Run or Run/Idle, engine is locked in idle speed. In Run/Idle position and Engine Control switch in Run/Idle, engine runs at idle speed at no load and weld/power speed under load.

To start: move idle lock switch and engine control switch to Start. Release engine control switch when engine starts.

.If the engine does not start, let the engine come to a complete stop before attempt- ing restart.

To Stop: turn Engine Control switch to Off position.

.Close fuel valve to stop engine if Engine Control switch does not work (see Section 4-3).

10 Output (Contactor) Switch

Use switch to control remote contactor if con- nected to remote 14 receptacle RC1 (see Section 5-2). Place switch in Remote 14 posi- tion if using remote contactor.

YWeld output terminals are energized when Output (Contactor) switch is in On position and engine is running.

11 Remote Amperage/Voltage Switch

Use switch to select front panel or remote am- perage/voltage control (see Section 5-2).

12 Remote 14 Receptacle RC3

Use receptacle to connect remote control (see Sections 4-8 and 5-2).
