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 con- trol 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 OUT- PUT control dial. During welding, the meter display the actual output voltage (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 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) dur- ing 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.
