Can anyone tell me the idle amperage (amperage when the machine is running but not welding) on a Miller Dialarc 250 AC/DC with power factor corection (PFC) when connected to a 230 VAC power supply? I've ran this maching for many years on only a 40 amp breaker (for 3/32" amd 1/8" 7018 rods only) but last weekend it blew the breaker for the first time when it was idleing. Maybe the breaker is getting weak? Appreciate your comments. Thanks
