CAUTION:
INCORRECT INPUT POWER can damage this welding power source. This welding power
Y
source requires a CONTINUOUS supply of 50/60 Hz (+10%) power at +10% of rated input voltage. Phase
to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with automatic
idle device (that idles engine when no load is sensed) to supply input power to this welding power
source.

1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
2 "Time-Delay" fuses are UL class "RK5" .
3 "Normal Operating" (general purpose - no intentional delay) fuses are UL class "K5" (up to and including 60 amp), and UL class "H" ( 65 amp and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
Y Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard. These
recommendations are for a dedicated branch circuit that applies to the rated output and duty cycle of the welding power source.
Actual input voltage should not exceed ± 10% of indicated required input voltage. If
actual input voltage is outside of this range, output may not be available.
