1 Power Switch
.
The fan motor is thermostatically
controlled and only runs when cooling is
needed.
2 Voltmeter (see Section 4-3)
3 Ammeter (see Section 4-3)
4 V/A (Voltage/Amperage) Adjustment
Control
5 Mode 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.
6 V/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.
