.The fan motor is thermostatically

controlled and only runs when cooling is needed.

4V/A (Voltage/Amperage) Adjust Control

5Voltage/Amperage Control Switch

For front panel control, place switch in Panel position and use the V/A Adjust control.

For remote control, make connections to Re- mote 14 receptacle, and place switch in Re- mote position. In most modes, remote control is a percent of the V/A Adjust control setting. Value selected on V/A Adjust is maximum

available on remote. In the MIG mode, re- mote control provides full range of unit output regardless of V/A Adjust control setting.

6 Mode Switch

The Mode switch setting determines both the process and output On/Off control (see Sec- tion 5-6). Source of control (panel or remote) for the amount of output is selected on the V/A Control switch.

For Air Carbon Arc (CAC-A) cutting and gouging, place switch in the Stick position. For best results, place Inductance/Dig con- trol in the maximum position.

7 Inductance/Dig Control

Control adjusts Dig when the Stick or CC mode is selected on the Mode switch. When

set towards minimum, short-circuit amper- age at low arc voltage is the same as normal welding amperage.

When set towards maximum, short-circuit amperage is increased at low arc voltage to assist with arc starts as well as reduce stick- ing while welding (see volt-ampere curves in Section 4-3).

Select setting best suited for application.

Control adjusts inductance when MIG posi- tion is selected on the Mode switch. Induc- tance determines the “wetness” of the weld puddle. When set towards maximum, “wet- ness” (puddle fluidity) increases.

When Pulsed MIG, or one of the TIG modes is selected, this control is not functional.
