WELDING CONTROLS
1. OUTPUT CONTROL:
The CONTROL dial provides continuous control of the
welding current or welding voltage depending on the
selected welding mode. This control is not active in the
CC-STICK, DOWN HILL PIPE, and CV-WIRE modes
when a remote control or wire feeder with remote control
is connected to either the 6 pin or 14 pin Amphenol.
2. DIGITAL OUTPUT METERS
The digital meters allow the output voltage (CV-WIRE
mode) or current (CC-STICK, DOWN HILL PIPE and TIG
modes) to be set prior to welding using the OUTPUT con-
trol dial. During welding, the meter display the actual out-
put voltage (VOLTS) and current (AMPS). A memory fea-
ture holds the display of both meters on for seven sec-
onds 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%.

4. ARC CONTROL :
The ARC CONTROL WIRE/STICK dial is active in the WIRE,
STICK and DOWN HILL PIPE modes, and has different func-
tions in these modes. This control is not active in the TIG 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 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 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
preferred for fill and cap passes where weld puddle con-
trol and deposition (“stacking” of iron) are key to fast trav-
el speeds. It is recommended that the ARC CONTROL
be set initially at 0.
