5-8. Installing Wire Spool and Adjusting Hub Tension
5-9. 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.
Input Voltage (V)
Input Amperes (A) At Rated Output
Max Recommended Standard Fuse Rating In Amperes
Normal Operating Fuses
Min Input Conductor Size In AWG
Max Recommended Input Conductor Length In Feet (Meters)
Min Grounding Conductor Size In AWG
Reference: 2011 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
310.15(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.
NOTICE − This unit is either a 200/230/460 ac input voltage model or 460/575 ac input voltage model. See rating label on unit and check voltage
available at site to be sure it matches the voltage specified on the rating label.
