I'm at my welding table practicing welding with a new torch, and I've

Can I do the same to correct a "run away hole" on real work? - Mike


There are certainly better welder than me on this group to advise you
but I'll give it a try.

Possibilities:

1. Your gas pressure is too high and you are blowing holes in the
metal. *Try using a smaller flame and working slower.

2. You aren't quick enough in pulling the flame back when you see the
metal starting to boil and spark. *If you see that, the heat needs to
be reduced NOW. *The only way to quickly reduce heat is remove the
flame.

Learning to weld it fun if a little frustrating. It brings out the
inner child - with pyromaniacal tendencies.


Thanks; any idea if I can "fill in my gaps" when off the practice
table? - Mike
