3-19. Electrical Service Guide
A. For 250 DX Models
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.
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.

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 3-5 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.
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.
