5-7. Electrical Service Guide
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommendations are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.

1If a circuit breaker is used in place of a fuse, choose a circuit breaker with
2
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).
4Conductor 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.
5-8. Extension Cord Data (Use Shortest Cord Possible)
.When calculating max. cord length, remember to include conductor length from line disconnect device to input power receptacle.
