Spot welds

[do8erman]

For the home restorer front fenders/ wings can be spot welded to inner fenders to represent original spots with tips available to achieve this ( info on here ) with a hand held machine . The A pillar seems a different story and there seems little info here on that . Not wishing to plug weld and clean which I assume is done on many do some people use a single sided machine for this ?  Would any one know a restoration company  in UK that would be prepared to spot weld panels that have been lightly plug welded to hold in place with there machine . Trying to find how mercedes done this but cannot find the assembly process on this model unlike some others . Overreaching yes but you never know   if you do not ask

I am sure Mercedes used custom, job specific, spot welding equipment and fixtures on the assembly line. In addition the exact sequence of spot welding panels in place was also critical.

The guy who rebuilt my chassis used a single sided machine in a few areas like along the fender tops.  He was obsessed with getting everything just so.  The single sided Lenco machine worked a treat.

Thank you for your replies  . It's a hire job from United welding or similar company or purchase and sell as new hardly used  when finished  second-hand kit like this seems to lose very little money now days with prices rising almost daily .

I just looked up the Lenco spotweld mark2 L-4000. I wish I had run across this about 10 years ago when I was welding the panels on the Roadrunner!!! Not cheap but when you are doing close to a 1000 spot welds, it pays for itself. The time savings alone would justify this machine over using plug welds. Looks like there are two electrodes. One does the actual spot weld and the other is a ground of sorts on the back side and doesn't have to be on the same spot as the spot weld.
