CONTROLS AND SETTINGS

All generator/welder controls are located on the Output Control Panel of the machine case front. Diesel engine idler control, and start/stop controls are also on the case front. See Figure B.1 and the expla- nations that follow.

ting of the OUTPUT RANGE SELECTOR. Never change the polarity switch setting while welding since this could damage the switch.

4. ENGINE STOP PULL CABLE: Allows the operator

to STOP the diesel engine by pulling out this con-

trol cable until the engine stops.

5. START PUSH-BUTTON: When the push-

button is held, the starter motor cranks over

the engine - release the Button once the

engine starts.

NOTE: If you press the START push-button when the engine is running, you may damage the ring gear or starter motor.

6.	OIL PRESSURE GAUGE: Indicates the amount of
	oil pressure present when the engine is running.
7.	BATTERY LIGHT: Is off when battery charging
	system is functioning normally. If the red light
	turns on while the engine is running the alternator
	or the voltage regulator may be defective.
8.	ENGINE HOUR METER: Records engine running
	time. Use to determine when to perform required
	maintenance.
9.	IDLER CONTROL SWITCH: The idler switch has

MACHINE CONTROLS

See Figure B.1 for the location of the following fea- tures:

1.OUTPUT RANGE SELECTOR: Selects continuous current output for constant current stick or TIG applications (blue settings) and constant voltage wire feed applications (red settings). The amper- ages on the dial correspond to the maximum amperages for each corresponding range setting. Never change the range switch setting while weld- ing since this could damage the switch.

2.FINE OUTPUT CONTROL: Allows fine adjustment of current or voltage within the selected output range.

3.POLARITY SWITCH: Selects DC+, DC- or AC welding output. Color codings aid in the proper selection of stick (blue) or wire feed (red) polarity setting. On the RANGER 8+ DIESEL the color set- ting of the polarity switch must match the color set-

two positions. “HIGH” and “AUTO”.

When in “HIGH” ( ) position, the engine will run continuously at high speed.

When in “AUTO” ( / ) idle position, the idler operates as follows:

a)Welding

When the electrode touches the work, the weld- ing arc is initiated and the engine accelerates to full speed.

Pressing the gun trigger or Amptrol causes the engine to accelerate to full speed.

After the gun trigger or Amptrol is released and/or welding ceases (and no auxiliary power is being drawn), the engine will return to low idle after approximately 10 to 14 seconds.

b)Auxiliary Power - With the engine running at low idle and auxiliary power for lights or tools is drawn (approximately 100-150 watts or greater) from the receptacles, the engine will accelerate to high speed. If no power is being drawn from the receptacles (and not welding) for 10-14 sec- onds, the engine will return to low idle.
