Sheet metal, like the body panel, can be welded with a 115 v mig welder like Hobart handler 140 if you are willing to do these 5 things. . . (
In fact, the 115 V mig welding machine is usually the best choice for welding sheet metal, and the Hobart Handler 140 has all the features needed to weld thin sheet metal or even up to \"thick steel. )
Don\'t even consider trying to weld in a car body patch with a flux core.
You need a MIG welder with a gas conversion kit so you can use 75/25 of the gas and use it.
Bare wire like E70s6 or E70s3.
Pure carbon dioxide is not what you want.
It is good to weld thicker steel, but for thinner sheet metal, 75/25 ar/Co2 is the ticket.
It is also more versatile.
Before you pull the trigger, you can change a good weld and a large piece of garbage that must be grounded even if it deviates slightly from the mark.
Buy yourself a decent auto darken welding helmet unless you like grinding.
When you pull the trigger on the MiG gun, it makes a big difference to be able to see exactly where your wire tip is.
Sheet metal is twisted when you weld. . . period.
You can\'t stop it, all you can do is try to control it and fix it.
The hammer and trolley used intermittently between small stitching welds is a pro way to prevent too much metal distortion.
Welding sheet metal requires a little patience and skill.
But if you\'re willing to follow the rulesYou can do it.
