I would go with the 220 units.
I have a Hobart 220. Hobart is Miller parts and consumibles .
Crank it way down to do your little sheet metal work and still have the capability to do serious (fun) welding.
I have used my Hobart 220 from everything from floor pans to building complete car trailers.
This is just me----- but, once you have a 110/120 unit you will wish you had a 220.
Example: welding through rusty/scale to obtain an even penetration is nearly impossible with the 110 units with out having to waste time with grinders/wire wheels and you'll only be able to do short welds (penetrating welds).
With a 220 unit you'll be able to get the heat up (stay up) to blow through rust/scale and still lay down beautiful welds--- without wasting hours with a grinder/wire wheel.

Agreed

^ yes and no.... yeah a bigger one will heat up alot quicker, and hold heat... but in bodywork you DO NOT want this... frame work, yes... or any other type that is more of a solid structure.. but def not on panels.... any panels... it will warp and cause you to have a much bigger body shop bill or headache with labor in fixing the warped panels.....

if you are doing alot of fab work, on various sizes of metal with it averaging 1/4" then yes I HIGHLY recommend a 220v welder... if you are just repairing small things on a car... 110....

[firebird79_00]

Mainly i will be doing a couple spots on the floor, a couple in the wheel wells and i need to fab up a 77 rear end. I may also have a spot on the quarter to do. If i was using a 220 would it be okay to use as long as im taking the time to cool the panel down between welds?

[eroc022]

yeah... you can set the heat and wire speed right and do the same as a 110....just go slower.... a cold wet rag... or cold air will aide in the cooling....

[Greenbird76]

I used compressed air for cooling between welds.  Worked well. 

[firebird79_00]

okay thanks, im going to try and pick up a 220 soon then.

a 115 volt  20 to 25 amp breaker at the box is fine for auto body.    dont use it on a 15 amp breaker , you'll cook the board in the welder.  unless the manual states a 15 amp breaker is fine.   

when weding auto body, you dont hold the trigger .  it 100's of spot welds.  and skip all around the patch or it will warp.   

if you use gas ,  use 75/25 mix.   it'll burn cleaner then argon.

agreed 100%

[Greenbird76]

And I paid about $120 for my tank and $30 a fill up from a local gas supplier.  One tank will last a while.  75/25 mix as Doug stated.
