We had a discussion on T4W about doing big jobs with a little welder. Here's an illustrative series of a full penetration butt weld in 1/4" plate using a welder that gives me 100A at most. It's not as pretty as it could be, but more practice on large sections will help there.

Start by cleaning up the edges and doing a *good* job of beveling both plates back about 45*.
