I have a welding plug in my garage that I would like to use for a machine (that isn't bought yet) but wondering if it's possible? My sp30 is runing off of two 15 amp circuits but I know they can run off of 220v and be more efficient.
You could get a 30 amp breaker, assuming you have the electricty compacity for it. Make sure to use proper electric cabling for it and nice plug. I would not go though the welding plug unless you are for sure the wire can handle the 220.
So it kinda varies on anwser depending on setup. But then you would go from receptical to PDU which allows both SP30's to run on it.
