Operation 4-4 Manual 0-5203
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 nuisance 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.
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/HF TIG weld modes.
Nuisance tripping should not occur on a 50A 208/230V outlet for both STICK & LIFT TIG/HF TIG Modes.
