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, 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, PIPE and TIG modes) to
be set prior to welding using the OUTPUT control dial.
During welding, the meter display the actual output volt-
age (VOLTS) and current (AMPS). A memory feature
holds the display of both meters on for 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%.

4. ARC CONTROL
The ARC CONTROL WIRE/STICK dial is active in the WIRE,
STICK and PIPE modes, and has different functions in these
modes. This control is not active in the TIG mode.
CC-STICK, PIPE modes In these modes, the ARC CONTROL
knob sets the short circuit current during stick welding (arc-
force). Increasing the number from -10 to +10 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 num-
ber without electrode sticking. Start with a setting at 0.
CV-WIRE mode: In this mode, turning the ARC CONTROL
clock wise from –10 (soft) to +10 (crisp) changes the arc from
soft and washed-in to crisp and narrow. It acts as an induc-
tance control. The proper setting depends on the proce-
dure and operator preference. Start with a setting of 0.
