∆ The recommended time delay fuse or circuit breaker size is 30 amp. An individual branch circuit capable of carrying 30 amperes
and protected by fuses or circuit breaker is recommended for this application. Fuse size is based on not more than 200 percent
of the rated input amperage of the welding power source (Based on Article 630, National Electrical Code)
