Never tried one, but spot welding relies on the two sheets being clamped tightly together - usually by the spot welder itself. That gizmo works from one side only so there is nothing making sure the panels are clamped tight exactly at the point of welding. I suppose if you push hard enough it could work, but I think I'd prefer to drill a hole and mig through it to achieve the same result. (if you have a mig welder).

Drill a hole and plug weld it.

I guess in theory, with two perfect sheets of metal, on the bench, it will make a reasonable spot weld but in the real world forget it. I've got one in a draw from about 1979. I suspect it will still be there when the vultures raid my workshop on the afternoon of my funeral.

i bougt that exact model a little while ago, used it a few times and dont know were it is now

it did stick the metal together but the actual weld was a bit pants, it severely thined the top layer to the extent that the top sheet of steel just peeled off like tin foil. did leave the weld intact though so could be called a success?!

makes very weak welds imho

Like jaykay and Andy I had one around the mid seventies and the carbon torch for brazing, waste of time and money to be honest.
