I know its a weird question but looking at buying a welder to do some sheetmetal repair on my jeep what is the gauge of the sheetmetal on the body panels and which way does the scale go for instance which is thicker 12 gauge or 24 gauge probably should know this but have never dealt with sheetmetal before thanks chris
Most of the Jeep body replacement panels are 16 or 18 gauge. The lower the number of the gauge, the thicker the metal.
I use a MIG welder with .030 solid MIG wire and CO2 gas to do most of my panel welding. I also use .035 flux core wire for heavier applications.

Lower the gauge the thicker and get the best welder you could afford. Don't just buy a welder to sheetmetal....get one that can weld 1/4".
This is very good advice. The Lincoln 125 will really only be good for sheet metal work. If you want to run anything thicker you'll have to make multiple passes, which means 2 to 3 times the work and wire. For just a few bucks more, you could easily upgrade to a higher capacity mig. If your stuck using a 120V machine look at the 140A models. Most with be set up for use with shielding gas. If you have 240V available, look into a 180A model. These machines are great for just about anything you'll have to tackle around the home or on any Jeep. Both of these mig welders can be dialed down for sheetmetal work and do an impressive job. It may be more than you want to spend, but if you buy a quality 180A mig, once your work is done, you could easily sell it for almost what you paid for it.
Outfits like Northern Tool and Tractor Supply Co. often sell the Hobart 187 for just under $600. The Lincoln's are probably about the same or a little less at any of the home centers.
I'll second the advice to get a good MIG setup. Flux-core will work well for odd jobs and stuff that doesn't need to be pretty, but MIG is much better, especially for body work. You can usually find good used machines for pretty good prices. I bought my flux-core, knowing what it would and wouldn't do, for about 100 bucks. I can't remember the model number, but it's a nice machine. I just wouldn't use it for body work. (Ugly welds, lots of spatter.)
