Google doesn't seem to reveal much more than what I remembered which the advice
to "just don't do it". I did find some vauge references to carbon embrittlement.
4130 shows up mostly in tubing no? I'm wondering if the "high strength" is
really "high carbon" and something about acetylene mixes with the carbon to do
something funky.

I wonder just what that "high strength steel" really is. I thought that chrome
moly 4130 was high strength steel, and I weld it all the time (with gas).

Honestly Karl its all about Clay starting with a junk welder and not listening
to any of the advice he's been given, he's making this as hard for himself as
possible. I've got a Lincoln Handy Mig and it can stick good clean 18ga metal
together all day without blowing through.
Try sticking it to the dubious crap that makes up an old car and things get
interesting. The trick there is to cut back far enough to find really solid
metal. Sometimes thats hard...
