Min Grounding Conductor Size In AWG
* Input amperes at rated output is the amperage draw for that particular input voltage if the machine is run at its rated welding
output (see Section 3-3 for rated welding output).
Reference: 2005 National Electrical Code (NEC)
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" .
3 "Normal Operating" (fast) fuses are UL class "K5" (up to and including 60 amp), and UL class "H" ( 65 amp 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.

All values in both tables were calculated at 60% duty cycle.
Actual input voltage cannot exceed ± 10% of indicated required input voltage
shown in both tables. If actual input voltage is outside of this range, damage to unit
may occur.
