WELDER/GENERATOR CONTROLS

See Figure B.1 for the location of the following features:

1.OUTPUT CONTROL: Allows full range adjustment of welding current or voltage.

2.ARC CONTROL: The “ARC CONTROL” is active in

two modes: “STICK/TIG” and “WIRE WELDING” with different purposes in each mode.

3.MODE SWITCH: Selects three possible modes of welding operation, 1.) CC Stick/TIG Welding, 2.) Pipe Welding, and 3.) CV Wire Welding.

4.LOCAL/REMOTE CONTROL SWITCH: Allows the operator to control welding output at the welding con- trol panel or at a wire feeder, TIG amptrol, or a K857 remote control.

5.CONTACTOR SWITCH: The toggle switch labeled “WELDING ON” and “CONTACTOR CONTROLLED” is used to control the operation of the solid state out-

safest grounding procedure.
