| ing. First off, I used two different welders. The first was just a plain MIG welder with flux core wire. I experienced a ton of burn through with this welder and it was turned all the way down. At the seams of the car there are often more than two pieces of metal that come together. These pieces are really thin. I would say 20 - 24ga. I was really surprised. Unlike in some areas like the hatch that was around 16 - 18ga. The two seam in the door jam was the hardest one IMHO. With a straight MIG welder and flux core wire it cooked through it. Didn't matter what I did with that welder it burned through. I put the welder aside and went to a MIG welder with shielding gas. With the GMAW welder and solid wire after fine tuning the heat range it welded pretty good. Good for not back flowing the car frame or any of that. If I were you and with no previous welding experience I wouldn't even think of trying car body panels out. They're super thin most of the time. Thin metal is harder to weld than thick metal. Thick metal all you have to do is make sure you have your bevels right and your gap between the work pieces and weld away. Then you burn through it and then your stuck trying to add metal to the panel with a welder to fix a oopps. Start with a good Gas Metal Arc Welder or a Tungsten Inert Gas Welder if you have the money. Then get some good 1/4 steal and practice welding on that. Work on but joints at first. Then go to overlap joints. Then after you feel good there start stepping your metal thickness down so you can work into having to deal with the quick disappearing act then metals can pull. If you didn't understand most of that then get a welding how to book and read, read, read some more.
