4V/A (Voltage/Amperage) Adjustment Control

5Mode Switch

The Mode switch setting determines both the process and output On/Off control (see Sec- tion 5-3).

For Air Carbon Arc (CAC-A) cutting and goug- ing, place switch in Stick position. For best re- sults, place Arc Control in the maximum posi-

tion.

6 Remote 14 Receptacle

For remote control, make connections to Re- mote 14 receptacle. In TIG modes and the REMOTE STICK mode, remote control is a percent of V/A Adjust control setting (value selected on V/A Adjust is maximum available on remote). In ELECTRODE HOT STICK mode the remote control is not used. In the MIG mode, remote control provides full range of unit output regardless of V/A Adjust control setting.

7 Arc Control

Control adjusts Dig when Stick or CC mode is selected on mode switch. When set towards minimum, short-circuit amperage at low arc

23

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.

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.
