So I am welding in the Tangerine Racing inner consol reinforcement. If I have the welder set on three it doesn't bite into the ear. If I have it set on four it bites but it blows holes in the new piece. I was able to get two holes filled and they are definitely welded on. However, I am wanting to know before I do more if going on the four setting will be right and not damage anything. Three just doesn't seem to cut it.

I learned to weld body metal with a ac stick welder. There is a stitch welder attachment for the stick welder, I bought one but decided to just go to the mig instead and now tig.
Take two pieces of the new metal or some of the same thickness and practice lap welding on them with the settings. With one good piece and one thinner piece you can start the arc on the thicker piece and mostly stay on it and go off the edge to the thinner piece to melt it but not blow through. The max amp will be what you can use to get good penetration but not blow through the thinner metal. Welding rusted metal will never be pretty and usually requires a lot of griding, just hopefully you will get good and strong welds and they won't crack in about 3 yrs. Usually if it's going to crack it will happen right as it's cooling off from uneven cooling. When it blows through you can stop and start with small spot welds and build the edges up till they are heavy enough to hold the full heat of a continuous weld. As you weld the surrounding metal will get to where the red glow doesn't dissipate as quickly as it needs to so you need to go to another spot and work there till it gets too hot and so on. The longer cord doesn't sound too good to me but it's your equipment. That will mean the cord is dropping some of the amperage and that means the plugs and extension wire will run hotter and also the electrical parts in the welder maybe and so on. Copper or any heat sink that the mild steel won't stick to, backup works great if you can get to the backside. Also I don't have or know about 110v welders but hopefully you are using .023 wire. |
