1 Power Switch
The fan motor is thermostatically con-
trolled and only runs when cooling is
needed.
2 Voltmeter (see Section 3-5)
3 Ammeter (see Section 3-5)
4 V/A (Voltage/Amperage) Adjust Control
5 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 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, remote
control provides full range of unit output re-
gardless 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 3-6). 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 goug-
ing, place switch in the Stick position. For best
results, place Inductance/Dig control 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 amperage
at low arc voltage is the same as normal weld-
ing amperage.
When set towards maximum, short-circuit am-
perage is increased at low arc voltage to assist
with arc starts as well as reduce sticking while
welding (see volt-ampere curves in Section
2-3).
Select setting best suited for application.
Control adjusts inductance when MIG position
is selected on the Mode switch. Inductance
determines the "wetness" of the weld puddle.
When set towards maximum, "wetness"
(puddle fluidity) increases.
When Pulsed MIG, or one of the TIG modes is
selected, this control is not functional.
