SECTION 4 – OPERATION

4-1. Front Panel Controls For CC/CV Model

1 Power Switch

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

2Voltmeter (see Section 4-3)

3Ammeter (see Section 4-3)

4V/A (Voltage/Amperage) Adjustment Control

5Mode Switch

The Mode switch setting determines both the process and output On/Off control (see Sec- tion 4-4). 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 Stick position. For

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

6V/A (Voltage/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 con- trol is a percent of 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

7 Inductance/Dig Control

Control adjusts Dig when Stick or CC mode is selected on mode switch. When set to-

wards minimum, short-circuit amperage at low arc voltage is the same as normal weld- ing 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 2-3).

Select setting best suited for application.

Control adjusts inductance when MIG or V-Sense Feeder position is selected on the mode switch. Inductance determines the “wetness” of the weld puddle. When set to- wards maximum, “wetness” (puddle fluidity) increases.

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