After a few difficult sessions on the Morris truck attempting to "spot" weld a
new driver's floor brace, I switched over to "plug" welding and suddenly I was
flying along. Better welds, no duds, and finished in no time.
For the beginner welders out there like me, to spot weld with a mig rig, you
drill a hole through one piece and then fill the hole with weld and hope it
penetrates to the undrilled piece beneath. With plug welding, drill (~3/16")
through BOTH pieces, back the hole with a small piece of brass or copper, THEN
fill the hole with weld. What a difference in success. All the good welders
on the list are saying "DUH!", but at least I'm learning. (And I got a
rock-solid floor brace!)
