6. OIL PRESSURE GAUGE
The gauge displays the engine oil pressure when the engine is
running.
7. ENGINE PROTECTION
The yellow engine protection light remains off with proper oil
pressure and under normal operating temperatures. If the light
turns on, the engine protection system will stop the engine. Check
for proper oil level and add oil if necessary. Check for loose or
disconnected leads at the oil pressure sender located on the
engine. The light will remain on when the engine has been shut
down due to low oil pressure or over-temperature condition.
8. BATTERY CHARGING LIGHT
The yellow engine alternator light is off when battery charging
system is functioning normally. If light turns on, the engine
protection system will shut down the engine. Check the Engine
cooling blower belt. Also the alternator or the voltage regulator
may not be operating correctly. The light may also come on due
to a faulty flashing circuit. The light will remain on when the
engine is stopped and the run/stop switch is in the run position.
WELDING CONTROLS (Items 9 through 17)
9. OUTPUT CONTROL: The OUTPUT dial is used to preset the
output voltage or current as displayed on the digital meters for the
four welding modes. When in the CC-STICK, DOWNHILL PIPE or
CV-WIRE modes and when a remote control is connected to the
6-Pin or 14-Pin Connector, the auto-sensing circuit automatically
switches the OUTPUT CONTROL from control at the welder to
the remote control. In the CV-WIRE mode, when the wire feeder
control cable is connected to the 14-pin connector the auto-
sensing circuit automatically makes OUTPUT CONTROL inactive
and the wire feeder voltage control active.
When in the TOUCH START TIG mode and when a Amptrol is
connected to the 6-pin Connector, the OUTPUT dial is used to set
the maximum current range of the CURRENT CONTROL of the
Amptrol.
10. DIGITAL OUTPUT METERS:
The digital meters allow the output voltage (CV-WIRE mode) or
current (CC-STICK, DOWNHILL PIPE and TIG modes) to be set
prior to welding using the OUTPUT control knob. During welding,
the meters display the actual output voltage (VOLTS) and current
(AMPS). A memory feature holds the display of both meters on
the seven seconds after welding is stopped. This allows the
operator to read the actual current and voltage just prior to when
welding was ceased. While the display is being held the left-most
decimal point in each display will be flashing. The accuracy of the
meters is ± 3%.

12. ARC CONTROL:
The ARC CONTROL WIRE/STICK knob is active in the WIRE
and STICK modes, and has different functions in these modes.
This control is not active in the TIG mode.
CC-STICK mode: In this mode, the ARC CONTROL knob sets the
short circuit current (arc-force) during stick welding. Increasing
the number from -10(Soft) to +10 (Crisp) increases the short
circuit current and prevents sticking of the electrode to the plate
while welding. This can also increase spatter. It is recommended
that the ARC CONTROL be set to the minimum number without
electrode sticking. Start with a setting at 0.
DOWNHILL PIPE mode: In this mode, the ARC CONTROL knob
sets the short circuit current (arc-force) during stick welding to
adjust for a soft or a more forceful digging arc (Crisp). Increasing
the number from -10 (Soft) to +10 (Crisp) increases the short
circuit current which results in a more forceful digging arc.
Typically a forceful digging arc is preferred for root and hot
passes. A softer arc is preferred for fill and cap passes where
weld puddle control and deposition (“stacking” of iron) are key to
fast travel speeds. It is recommended that the ARC CONTROL
be set initially at 0.
CV-WIRE mode: In this mode, turning the ARC CONTROL knob
from -10(soft) to +10(crisp) changes the arc from soft and
washed-in to crisp and narrow. It acts as an inductance/pinch
control. The proper setting depends on the procedure and
operator preference. Start with a setting of 0.
13. WELDING TERMINALS SWITCH
In the WELD TERMINALS ON position, the output is electrically
hot all the time. In the REMOTELY CONTROLLED position, the
output is controlled by a wire feeder or amptrol device, and is
electrically off until a remote switch is depressed.
