1 Power On/Off Switch

.The fan motor is thermostatically controlled and only runs when cooling is needed.

4Voltage/Amperage Adjustment Control

5Mode Switch

The Mode switch setting determines both the process and output On/Off control (see Sec- tion 4-3. Source of control (panel or remote) for the amount of output is selected on the Voltage/Amperage Control switch.

For Air Carbon Arc (CAC-A) cutting and gouging, place switch in Stick position. For

best results, place Inductance/Dig control in the maximum position.

6 Voltage/Amperage Control Switch

For front panel control, place switch in Panel position.

For remote control, make connections to Re- mote 14 receptacle, and place switch in Remote position. In most modes, remote control is a percent of the Voltage/Amperage Adjustment control setting (the value se- lected on Voltage/Amperage Adjustment control is maximum available on remote). In the MIG mode, remote control provides full range of unit output regardless of V/A Adjust control setting.

7 Inductance/Dig Control

Control adjusts Dig when a Stick (SMAW) welding position is selected on mode switch.

When set lower, short-circuit amperage at low arc voltage is the same as normal welding amperage.

When set higher, short-circuit amperage is in- creased at low arc voltage to assist with arc starts as well as reduce sticking while weld- ing (see volt-ampere curves in Section 3-3).

Select setting best suited for application.

Control adjusts inductance when a MIG (GMAW) position is selected on the mode switch. Inductance determines the “wetness” of the weld puddle. When set higher, “wet- ness” (puddle fluidity) increases.

When pulsed MIG, or one of the TIG (GTAW) processes is selected, this control is not func- tional.
