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 amperage and GTAW applications. Turn clockwise to increase short-circuit amperage.

2 Process Selector Switch

•GMAW Mode: For use with flux Cored (FCAW) or submerged arc (SAW) applica- tions.

•SMAW (Hot Start On) Mode: Hot Start is energized for Stick (SMAW). When Hot Start is energized, higher short circuit am- perage aids in arc starting. NOTE: use the Positive (+) High Inductance weld output terminal (see Section 4-9).

•SMAW (Hot Start Off) Mode: For use with TIG (GTAW), scratch start only, or sub- merged arc (SAW) applications. NOTE: for GTAW, use the Positive (+) High Induc-

tance weld output terminal (see Section 4-9).

3 Amperage/Voltage Adjustment Control

When Process Selector switch is in the SMAW/GTAW position, turn control clock- wise to increase amperage. Read amperage from outer scale of control. When Process Selector switch is in the GMAW position, turn control clockwise to increase voltage. Volt- meter value changes as control knob is turned. Control can be adjusted while welding.

4 Digital Meters

With Process Selector switch in the SMAW/ GTAW position, digital meters will read 0 (zero) with contactor off. Digital meters will display actual output voltage and amperage with contactor on.

With Process Selector switch in the GMAW position, voltmeter displays preset voltage with contactor off. Voltmeter and ammeter

display actual output voltage and amperage with contactor on.

5Power Switch With Indicator Light

6High Temperature Shutdown Light

7Remote Amperage/Voltage Control Switch

For front panel control, place switch in Panel position. For remote control, place switch in Remote position, and connect remote de- vice (see Section 4-15).

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 4-15).

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

! Turn Off power before connecting re- mote device.
