5-4. Front Panel Controls For CC/CV Models
1 Power Switch
.
The fan motor is thermostatically
controlled and only runs when cooling is
needed.
2 Voltmeter (see Section 5-5)
3 Ammeter (see Section 5-5)
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, re-
mote control provides full range of unit output
regardless of V/A Adjust control setting.

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.

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.
