OPERATION
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 tem-
peratures. If the light turns on, the engine protection
system will stop the engine. Check for proper oil and
coolant levels and add oil and/or coolant if neces-
sary. 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 as
long as the Run/Stop switch is in the Run position.
NOTE: This engine is equipped with an electronic
governor system. The engine speed ramps
up during a warm up period. The complete
cycle takes approximately 3 minutes. This
allows the engine cylinder temperature to
build up slowly before going to full speed.
This feature is bypassed if the engine is
already warm. The Engine may produce
“White Smoke” for a few minutes at low tem-
peratures. Do not apply a load to the
machine during the warm up period.
8. BATTERY CHARGING LIGHT
The yellow engine alternator light is off when battery
charging system is functioning normally. If light turns
on the alternator or the voltage regulator may not be
operating correctly. 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 feed-
er voltage control (if present) active.
When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6-pin Connector, the OUT-
PUT dial is used to set the maximum current range of
the CURRENT CONTROL of the Amptrol.
10. DIGITAL OUTPUT METERS: (Optional)
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 OUT-
PUT 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 volt-
age 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%.
11. WELD MODE SELECTOR SWITCH:
(Provides four selectable welding modes)
CV-WIRE
DOWNHILL PIPE
CC-STICK
TOUCH START TIG
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 pre-
vents sticking of the electrode to the plate while weld-
ing. This can also increase spatter. It is recommended
that the ARC CONTROL be set to the minimum num-
ber without electrode sticking. Start with a setting at 0.
DOWNHILL PIPE mode: In this mode, the ARC CON-
TROL knob sets the short circuit current (arc-force)
during stick welding to adjust for a soft or a more force-
ful 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 pass-
es. 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 CON-
TROL 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.
