1 Output Selector Switch

YDo not use AC output in damp areas, if movement is confined, or if there is danger of falling. Use AC output ONLY if required for the welding process, and then use a remote control.

YDo not change position of switch while welding or while under load.

Use switch to select Direct Current Electrode Negative (DCEN), AC, or Direct Current Elec- trode Positive (DCEP) output without changing weld output cable connections.

2 Amperage Adjust Control

For Stick (SMAW), use control to adjust amperage.

For remote amperage control used when TIG (GTAW) welding, front panel Amperage control setting is the maximum amperage available at the remote control device.

See Section 3-3 for example of remote amper- age control.

3 Weld Process Switch

Use switch to select weld process.

In Stick position (up), weld output goes On and Off with Power switch.

In GTAW (TIG) position (down), remote control device turns on and adjusts weld output of unit as limited by Amperage control. For Direct Cur- rent Electrode Negative (DCEN), built-in arc starter comes on when needed to start or stabi-

lize welding arc. For AC welding, the arc starter will turn on and stay on to start and stabilize the welding arc. No adjustments needed for arc starter.
