Default Zen and the sticking RG-45 rod

It would seem that my last post drug out every old lurker that's ever
been on RAH (except Chuck... what's he up to these days?) Even BWB
sent me an unearthly vibe the other day.

But now that I have the torch, I've got a serious welding question.
Two actually. Number one is: anyone ever get firebrick from the Borg?
I've looked, but not scored any.

Second question: It seems that every time I dip the filler rod into
the puddle (shuddup and think about welding for a minute), every time
I dip the rod into the puddle, it sticks to the base metal and I end
up melting it off with the torch which I know isn't right based on the
shower of sparks. Any idea what I'm doing wrong? For the record, I'm
using the standard H-F torch, thier size "0" tip, and I've had the
same experience on both 16 ga. flat sheet (just trying to run a bead,
not joining) and on 2" square tubing (butt joint). I've got less than
15 minutes experience so far, but it would be helpful to know what I'm
doing or not doing wrong.

Thanks in advance,
Harry




Are you pre-heating the rod as you bring the puddle up to temp, Harry?

Sticking a cold rod into the puddle is guaranteed to freeze the puddle.
So bring the rod in close enough to the flame that it's is approaching the
melting point too.



Read Budd's "how to" article - Zen and the Weld Puddle.
A humorous but very helpful piece.
