1Polarity Selector Switch (Optional On 50 Hz Models)

To change polarity on models not equipped with a Polarity Selector switch, reverse work and electrode cables at the weld output termi- nals (see Section 4-9).

! Turn Off Power before reversing cables.

2 Arc Force (Dig) Control

Control increases SMAW short-circuit amper- age which allows the operator to use a very

short arc length without sticking the electrode.

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

3 Hot Start Switch

Turn switch On for SMAW and Off for GTAW welding.

4Amperage Adjustment Control

5Digital Meters (Optional)

6Power Switch With Indicator Light

7High Temperature Shutdown Light

8 Remote Amperage Control Switch

For front panel control, place switch in Panel position. For remote control, place switch in Remote position, and connect remote device (see Section 4-12).

9 Output Switch (Contactor)

For front panel control of output, place switch in Panel position. For remote control of output, place switch in Remote position, and connect remote device (see Section 4-12).

! Turn Off power before connecting re- mote device.
