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.
FIGURE B.1
OUTPUT PANEL CONTROLS
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-
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
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.
