Well I had time to work on this battery spot welder exterior controller

The test results went well and the concept will work now I have mount everything in the controller case and fix the transformer and welder fixture and hook up amp meter and volt meter

Update

Well things did not go very well not everything would fit in this case so I had to go with plan “B” which is to cut down the the heat sink and put the triac back on the controller board again —>

this actually went better than I thought it would in that I cut the heat sink the width as the triac and a piece of non conducive paper that is used for making battery packs and put it on the circuit board so it would not short out

Now I have figure out how I am going to mount the small controller transformer and where

I also have to figure out how to mount the amp and volt meters on the face plate of the welder which will be a challenge because of how the welder arms are

There is also another challenge with welder arms because I change the configuration of the transformer secondary winding wires and where they go so I have to buy some welding wire that fit the welding arms

I will post some pictures when I get done with this project
