4-13. Electrical Service Guide
NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of
input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera-
tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.
NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input
voltage is outside this range, output may not be 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 If a circuit breaker is used in place of a fuse, choose a circuit breaker with time-current curves comparable to the recommended fuse.
2 "Time-Delay" fuses are UL class "RK5" . See UL 248.
3 "Normal Operating" (general purpose - no intentional delay) fuses are UL class "K5" (up to and including 60 amps), and UL class "H" ( 65 amps 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
310.15(B)(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.
