I. 8 Pin Remote Socket
The 8 pin remote socket is used to connect the TIG Torch
Trigger Switch to the welding Power Source. To make con-
nections, align keyway, insert plug, and rotate threaded
collar fully clockwise.

NOTE!
Remote Welding Current Control is available
through the front panel of this unit. The remote
will only go to the maximum value that is set at the
panel. If the panel is set to 100 amps, the remote
can't go above 100 amps when fully adjusted.
J. ON/OFF Switch (located on rear panel not shown)
This switch controls the Mains Supply Voltage to the
Power Source.
4.03 Welding Current Control
Explanation
15 Amp Outlet
The mains power 15 Amp circuit breaker or fuse should
not trip at this Weld Current value when STICK welding.
The environmental conditions that may cause the mains
power 15 Amp circuit breaker or fuse to trip are:
a) High ambient temperature
b) Worn parts in circuit breaker
c) Using an extension cable
d) Low line mains power voltage
20 Amp Outlet
The mains power 20 Amp circuit breaker or fuse should
not trip at this Weld Current value when STICK welding.
The environmental conditions that may cause the mains
power 20 Amp circuit breaker or fuse to trip are:
a) High ambient temperature
b) Worn parts in circuit breaker
c) Using an extension cable
d) Low line mains power voltage
Output Scale for 115V
The inside number scale identifies the available
output weld current for STICK or LIFT TIG weld modes.
STICK Mode: Identifies the STICK weld point for 15
Amp outlet.
Identifies the STICK weld point for 20
Amp outlet.
Exceeding these points will cause nui-
sance tripping of the circuit breaker or
fuse.
LIFT TIG Mode/HF Mode: A 15 Amp outlet is capable of
supplying enough input power for all TIG
(GTAW) output weld current values.
NOTE!
Nuisance tripping should not occur on a
15 Amp outlet.
