4. ARC CONTROL
- The ARC CONTROL dial is active
in the CV-WIRE, CC-STICK and DOWNHILL PIPE
modes, and has different functions in these modes. This
control is not active in the TIG mode and ARC
GOUGING mode.
CC-STICK mode: In this mode, the ARC CONTROL dial
sets the short circuit current (arc-force) during stick weld-
ing to adjust for a soft or crisp arc. Increasing the dial
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 recom-
mended 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 CON-
TROL dial 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 pre-
ferred 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 clock wise 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.
5. WELD OUTPUT TERMINALS WITH FLANGE
NUT-
Provides a connection point for the electrode and
work cables.
6. GROUND STUD-
connecting the machine case to earth ground.
7. 6-PIN CONNECTOR-
control equipment. Includes auto-sensing remote control
circuit.
8. WELD TERMINALS CONTROL SWITCH-
WELD TERMINALS ON position, the output is electrically
hot all the time. In the REMOTELY CONTROLLED posi-
tion, the output is controlled by a wire feeder or amptrol
device, and is electrically off until a remote switch is
depressed.

9. RUN/STOP SWITCH
engine prior to starting. STOP position stops the engine.
The oil pressure interlock switch prevents battery drain if
the switch is left in the RUN position and the engine is
not operating.
10. GLOW PLUG PUSH BUTTON
• When pushed activates the glow plugs. Glow plug
should not be activated for more than 20 seconds con-
tinuously.
11. START PUSH BUTTON
motor to crank the engine.
12. IDLER SWITCH
- Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
2) In the AUTO
as follows:
• When switched from HIGH to AUTO or after starting
the engine, the engine will operate at full speed for
approximately 12 seconds and then go to low idle
speed.
• When the electrode touches the work or power is
drawn for lights or tools (approximately 100 Watts mini-
mum), the engine accelerates and operates at full
speed.
• When welding ceases or the AC power load is turned
off, a fixed time delay of approximately 12 seconds
starts. If the welding or AC power load is not restarted
before the end of the time delay, the idler reduces the
engine speed to low idle speed.
• The engine will automatically return to high idle speed
when there is welding load or AC power load reapplied.
13. ELECTRIC FUEL GAUGE-
gauge gives accurate and reliable indication as to how
much fuel is in the fuel tank.
