Bought a welder, a Lincoln Century 80. Just a little flux core 115 VAC, 80A unit good for up to 1/8".

Works good, this is my first weld.

Nice. I have to see about doing some lighter weld with a MIG for both flux and inert sheld gas weld.

I have a 130 that runs on 115 volts.

I want to fold and bend some steel to a shape for covers over delacate carb linkages and also moving pulleys and belts for safety. I think it would be OK if I can get it right so I don't burn through all and never attach what I make lap joints for in the folds.

lap joints are a good trick , heres another 1 you can try if butt welding to light gauge metal an I can get behind it I will clamp a peice of 1/4 inch thick copper plate behind the weld you can weld all day on that copper an it will never stick or burn through.

So you get enough heat to the work and welds OK, but its sort of the same as laying the metal on a thick metal table as the table is ground an weld the two pieces of metal.

Moderates the heat some I guess.

MT if its a steel tabe you can weld your peice to it steel dont stick to copper . but yes the copper will wick away any excess heat .

If I need to fill small holes I've used a penny clamped to the metal behind the hole then rosetta weld. When you're done the penny will come off and leave a welded shut hole in its place. Good when doing auto body stuff and filling screw holes where chrome or parts were attached to the body.
Magnets are also useful for holding small, hard to clamp parts in place until you get them tacked together.

I got a few magnets meant for welding, those triangle laminate with steel of various sizes.

When I got the minimal training to use time at a shop welding we had a thick metal table, but stuff stuck to it as it was steel. They used a wire brush occasionally to clean off weld splash beads.

It was said that with the magnets holding the pieces to weld on the table and the table had the ground clamp connected that enough current flows for what otherwise small pieces the clamp connection would be impractical.

You’ve explained about the copper and that it does not stick but is a very good heat sink, thanks.

What would be a good guage metal to make a seat pan from. It will have no springs and will be pretty close to the rear fender.
