Well I am going to learn to weld. Got to start somewhere... I've had a handful of around the house stuff that has made me think the thought, "If I only had a welder". And now I've got two vehicles that are slowly rusting away in my driveway. They are both 84's and are diesels (GMC 6.2 Diesel Suburban, and Mercedes 300d turbo diesel) that run great but like anything old that's been kept outside and driven in winters, they're slowly fading away because of rust and I'd like to squeak another 10 years out of them.
All that said, I'm excited. I'm 28 and have been interested in welding since I was a kid. I'm pretty mechanical and am an Electric Engineer by degree. I've always been a get it done kid. Make it if you don't have it or rig it if you can't afford to fix it with a new part.
So... a welder is going to a invaluable tool!! Time to get one.
Anyways, here is my first project (rusted wheel wells on the MB and rusted out hole in the door panel on my suburban). Where do I start?
Here are my questions:
1. From reading, I'm guessing MIG is the easiest form of welding for body work. I've also read Oxy Acetylene is what people used in the olden days. That is also something I may be interested in because I can pickup an old rig (estate deal) locally for around $350 (tanks, torch, hoses, regulators). But I've also read it's hard to do. I don't know much about it.
2. If I do go MIG, I'm guessing I need something that'll be low AMPs for that thin of material. I also only have a couple 220V connections so 110V may be easier for me. But what do I need if I go MIG? If I buy used, should I expect problems if I buy a major brand (Hobart, Miller, Lincoln). I'm guessing I'll have to spend another $100-200 in tanks hoses etc. Should I expect to pay around $700 when all is said and done if I get a 130A - 140A model? That's expensive for me, maybe I could get by with O/A??? Can I do heavier steel with O/A than I could do with a 110V MIG
3. Where do I get steel stock? Sheet Metal for the car?
4. What kind of basic tools would I need to shape the metal?
Thanks so much!!!! I'm very much looking forward to learning the trade!
lastly... there are also rust holes in the floor board (almost like a line was cut out along the front edge of the back seat and the line continues along the edge of the floor near the passenger door). It's about a 10" line on both openings. A big L shaped rusted out.
