These recommendations are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source. NOTICE . INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of input power at rated frequency10%) and voltage 10%). 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. 60 Hz Single Phase Input Voltage (V) 208 230 Input Amperes (A) At Rated Output 33 30 Max Recommended Standard Fuse Rating In Amperes 1 Time-Delay Fuses 2 Normal Operating Fuses 3 40 50 35 45 Min Input Conductor Size In AWG 4 3 10 Max Recommended Input Conductor Length In Feet (Meters) 80 (24) 98 (30) Min Grounding Conductor Size In AWG 4 10 10 Reference: 2008 National Electrical Code (NEC) (including article 630) 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 310.16. 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. 4-9. Extension Cord Data .
