440 volt is three phase. 220 volt is single phase, they are not interchangable or adaptable.

I have a generator designed 440V but the problem is I can use only 220V and the 440V cannot


440 volts is normally 3 phase so unless you have a suitable 3 phase plug it will only be 220 volts
read your user manual carefully

I have a 440v 50 amp and a 220v 30amp main breaker box outside my house. the 440 goez to the inside of the house and i have to unplug the 440 and plug in myown 440 plug i connected to another breaker box...


Some of these numbers don't make sense?
I have Never heard of 440v and 220v in a residential application, they are two different systems, 480 volt is typically 3 phase power, and 240v is typically single phase, more in likely you have a 200- 400 amp main service, and a 100- 200 amp secondary service for the welder, that can't be 110 @ 200 amps?
I would need more info, and pictures of actual nameplates of the equipment,
and then I could advise a safe NEC electrical code answer...

Wire schematic


If the welder is single phase 110v use a dedicated 20A standard household circuit. If 220v single phase use a 50A RV or weld receptacle connected to a 50A dual breaker with common trip. Make sure the breaker is the same brand as your panel. If the welder is 3-phase connect the wires B-O-Y (Brown Orange Yellow) at the breaker (3 phase 50A) and see if a color code match can be applied at the welder, although the only issue is whether the wire feed will run forward or reversed. If the wire feed is reversed then move any two wires of the B-O-Y set to change the rotation.

Make extension 220 volt cord for 220 volt welder


most 220v welders have a NEMA 10-50 plug or the NEMA 6-50 plug--the input /output ratings thru recepticle and thru plug are same-configuration of plug prongs are different( Grainger Catalogue shows simularities and differences) main difference is AC Horsepower Ratings are different, and that applies Only on equipment that uses 3 phase, not your welder.Use an Ohmmeter to touch unpowered wire connection under shroud at ground and plug prong, then red power connection to corresponding plug prong, and again to black connection and plug prong,mark them w/ felt pen w/ corresponding colors (Green, Black Red). Change out wire plug to fit into dryer or stove recepticle, or make an extention adapter plug witch fits stove recepticle and extends out thru floor to carport and goes to 10-50 recepticle-whereas ground green goes to W position (Center) Y is Black and goes to Y Black, X is Red and goes to X red and cap off the white neutral coming from plug -welders and hot water tanks do not return unused electrcity via the white neutral (return) wire--they use up what is available on demand in heating elements or in welders - the electromagnetic field.GET HELP DOING THIS, by someone who has knowledge, SKILLS and EXPERIECE. I have 1 welder fitted to go into dryer plug which has 14-30 recepticle, and i have 1 where i kill stove circuit at panel, unplug stove, plug in 14-50 plug which has a 10-50 recepticle on other end, plug in welder 10-50 -p, flip cicuit breaker switch to on-welder has full power range capacity. No oven in use while welder going--but probably wouldnt run it anyway if on different circuit.Any doubts whatsoever--anything not 100% clear--DO NOT DO THIS or any other Electrical Manipulations--have a licensed electrician stub in a secondary circuit breaker off your main if load is acceptible and have him wire in the recepticle which your plug will fit into---.

I have a capacitor marked 330v-140mfd which is best to use 440v-40mfd:550v:100mfd 220v-80mfd:330v:60mfd 440v-180mfd:220v-80mfd or can any be ok to use


If the mfd labeled is only 140 instead of a range i.e. 88-140 then it is a run capacitor and should only be replaced with a capacitor of the same mfd rating. Not using a run capacitor of the same mfd rating will cause the compressor motor windings to overheat and shorten the life of the compressor. The voltage is not as important. Generally, the higher the voltage rating the better the capacitor.
