1 Arc Force (Dig) Control

Control increases SMAW short-circuit amperage which allows the operator to use a very short arc length without sticking the electrode.

Set control at 0 for normal welding amper- age. Turn clockwise to increase short-circuit amperage.

2 Process Selector Switch

•Sub Arc Mode − For SAW (Sub Arc) ap- plications. NOTE: Use the (+) High Induc- tance (Submerged Arc) terminal.

•CC Mode − For SMAW (Stick), GTAW (TIG) − scratch start only, or SAW (Sub- Arc) applications. NOTE: For best results, use the Positive (+) High Inductance (Sub- merged Arc) weld output terminal.

•CV Mode − For FCAW (Flux Cored) ap- plications.

3 Amperage/Voltage Adjustment Control

When Process Selector switch is in the Constant Current position, turn control clockwise to increase amperage. Read am- perage from outer scale of control. When Process Selector switch is in the Constant Voltage position, turn control clockwise to in- crease voltage. Voltmeter value changes as control knob is turned. Control can be ad- justed while welding.

4 Digital Meters

With Process Selector switch in the Constant Current position, digital meters will read 0 (zero) with contactor off. Digital me- ters will display actual output voltage and amperage with contactor on.

With Process Selector switch in the Constant Voltage position, voltmeter dis- plays preset voltage with contactor off. Volt- meter and ammeter display actual output voltage and amperage with contactor on.

7Remote Amperage/Voltage Control Switch

•For front panel control, place switch in Panel position. With Control switch in the Panel position and Process switch in the CC position, Hot Start is energized for ACA (Air Carbon Arc Gouging) and SMAW (Stick) welding. When Hot Start is energized, higher short-circuit amperage helps arc starting. After arc starts, the Am- perage/Voltage control setting determines weld amperage.

•For remote control, place switch in Re- mote position, and connect remote device (see Section 4-11). NOTE: Hot Start is not energized when switch is in the Remote position.

8 Output Switch (Contactor)

For front panel control of output, place switch in Panel position. For remote control of out- put, place switch in Remote position, and connect remote device (see

Section 4-11).

! Weld output studs are energized only when Output switch is in On position, or while welding.

! Turn Off power before connecting re- mote device.
