5-2. Description Of Controls (See Section 5-1)
.The fan motor is thermostatically controlled and only runs when cooling is needed.
Engine Lights
1 Battery Charging Light
Light goes on if engine alternator is not charg- ing battery. Engine continues to run.
YStop engine and fix trouble if Battery Charging light goes on.
2 Engine Temperature Light
Light goes on and engine stops if engine tem- perature is too high.
YStop engine and fix trouble if Engine Temperature light goes on.
3 Engine Oil Pressure Light
Light goes on and engine stops if oil pressure is too low. Light goes on momentarily during
YStop engine and fix trouble if Engine Oil Pressure light stays on after start- up.
4 Glow Plug Light
Light goes on when glow plug is energized and warming up. Glow plug warms in about six seconds and engine can be started (see start- ing instructions following).
YDo not use glow plug longer than 20 seconds.

Weld Controls
7 Dig/Inductance Control
Control adjusts Dig when Stick mode is se- lected on mode switch. When control is set to- ward minimum,
When set toward maximum,
perage is increased at low arc voltage to as- sist with arc starts and help prevent the elec- trode from sticking while welding (see
Select setting best suited for application.
Control adjusts inductance when MIG or
When Pulsed MIG or one of the TIG modes is selected, this control is not functional.
8 Voltmeter
Meter displays weld voltage and help mes- sages (see Sections
9 Ammeter
Meter displays weld amperage and help mes- sages (see Sections
10V/A (Voltage/Amperage) Adjustment Control
11Mode Switch
The Mode switch setting determines both the process and output On/Off control (see Sec- tion
For Air Carbon Arc
12 V/A (Voltage/Amperage) Control Switch
For front panel control, place switch in Panel position and use the V/A Adjustment control.
For remote control, make connections to Re- mote 14 receptacle, and place switch in Re- mote position. In most modes, remote control is a percent of V/A Adjustment control setting (value selected on V/A Adjustment control is maximum available on remote). In the MIG mode, remote control provides full range of unit output regardless of V/A Adjust control setting.
Engine Starting Controls
13 Glow Plug Switch
Use switch to energize glow plug for cold weather starting. Glow plug warms in about six seconds and engine can be started (see starting instructions following).
14 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.
To Start:
Above 325 F: turn Engine Control switch to Start. Release switch when engine starts and Engine Oil Pressure light goes out.
.If engine does not start, let engine come to a complete stop before attempting re- start.
Below 325 F: turn engine control switch to Run/Idle position. Push Glow Plug switch up and hold about six seconds. Turn Engine Con- trol switch to Start. Release switch when en- gine starts and Engine Oil Pressure light goes out. Do not crank engine while engine is turn- ing.
.If engine does not start, let engine come to a complete stop before attempting re- start.
To Stop: turn Engine Control switch to Off position.
.Push engine stop lever to stop engine if Engine Control switch does not work (see item 15).
15 Engine Stop Lever
Use lever to stop engine if Engine Control switch does not work.
