if my garage is only wired for 110 but i wanna get an arc welder that takes 220
can i get a transformer or do they make step up transformers.
thanks

 

You won't have a 110 curcuit that carries enough amps to support a transformer to power a welder.

If your welder draws 20 amps at 220, it would require 40 amps on a 110 curcuit if you built the perfect 100% eff transformer.

Just run a 220 line for it. Easy enough.

 

220 should already be in your breaker box. double slot 25amp or 30 amp and youre good to go

 

i live in an apartment and the garages are just a shell pretty much.
they were nice enough to give us a 110 outlet and a light bulb.

 

Buy a generator that has 220v and enough amps to get the job done. 220v @ 20 amps will require about 4500watts continuous.

 

not a bad idea.^
generators are kinda pricey arent they. i supposed its good in the case of a disaster though.

 

If you have the time and money install a sub-panel. As c0mpl3x said. US = a pair of 110v inputs = 220v single phase right there. Put a breaker on both of your rails run to the sub-panel & install more breakers.
Now you can route 220 anywhere you want.

 

ALL INCOMING RESIDENTIAL LINES ARE 220v


the breaker box has 2 rails of hot. 110v uses one. 220v uses both.

you could rig up a jumper for 220v if youre ballsy enough

 

if im ballzy enough to get shot across the room?

 

How far away is your breaker box from your garage?

How many amps does your welder draw?
