THERMAL ARC 161 S OPERATION
Operation 4-2 Manual 0-5199
4.02 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: A 15 Amp outlet is capable of supply-
ing enough input power for all LIFT TIG
output weld current values.
Nuisance tripping should not occur on a 15 Amp outlet.
Output Scale for 208/230V
The outside number scale identifies the available output
weld current for STICK or LIFT TIG weld modes.
Nuisance tripping should not occur on a 50A 208/230V
outlet for both STICK & LIFT TIG Modes.
