3-5. Electrical Service Guide For 230 VAC

NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of
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.
.
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.
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for a dedicated branch circuit sized for the rated output and duty cycle of the 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.
