[TR] MIG welders

[Allen Hess]

I know this thread is getting a little stale but I'd add a couple  
points:

If you forget to turn on the gas you will get some pretty bad and  
ugly welds. It may be obvious but I've done it.

My experience with drilled out spot welds is this: If the old spot  
weld hole is too small, the weld tended to fill the hole and not  
penetrate the piece behind. Enlarging the hole about one drill size  
and it worked just fine.
