1 Output Selector Switch

YDo not use AC output in damp areas, if movement is confined, or if there is dan- ger 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 (DCEN) Direct Current Electrode Negative, AC, or (DCEP) Direct Current Electrode Positive output without changing weld output cable connections.

NOTE: Changing position of Out- put Selector switch may also change Process control, Current control, Output control, and Start Mode control settings to properly function with latest Output Selector switch setting.
