“What's Something You Want to Learn or Wish You Were Better At?” ( Archived) (22)

I would stay away from welding cast iron, that something only for very advanced welders to tackle. My advise is to start off with gas (Oxy Acetylene) You can weld sheet metal on up to 1/8" with no problem. anything thicker than that I would go with Arc welding, AC or DC depending on your budget. I used to build trailers for race cars so I've done a lot of welding over the years. My ex room mate used to work for a boiler repair co and there was a guy there named Mario who could weld by feel. He could weld without even being able to see the weld like between the top of a boiler and the ceiling. I knew another welder who could weld anything. He welded 2 cracked pistons in my race engine and I ran a whole season with them. He welded cracked cylinder heads all the time.
