Plug welding (AKA mig spot welding)

Post by parahandy 15 »

I have been doing a lot of this recently, vital to have clean shiny metal when migging.
not always happens though, does it? despite your best efforts.
When fixing a new panel on to an existing panel,drill through the punched holes with a drill the same size, just enough to expose bright steel in the lower panel,and the weld will stick like the proverbial. It also makes a dimple for the wire to locate in the middle of the hole.
Apologies if this has been posted already.
