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.

process and output On/Off control (see Sec-
tion 4-6). 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.

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
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 3-3).

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.

Sockets 1 and 2 are connected in parallel with
the Power switch. For remote On/Off control,
connect a suitable plug from a remote switch
to the receptacle and place front panel Power
switch in Off position. Unit can then be turned
On and Off through the use of the remote
switch.
