[AT] TIG welding--a little OT

Fri Mar 17 06:42:57 PST 2006

Bob,

My guess is that it is a combination of the high frequency and the intensity 
of the flame.  Seems to me that the TIG flame is hotter and brighter than 
arc welding.  Have you ever TIG'd aluminum?  A friend of mine does a lot of 
that.  The walls in his shop are unpainted pre-cast concrete .  You can 
stand in his shop while he's TIGing aluminum with your back to him and the 
reflection off the walls is enough to make you feel like your eyes are 
getting burned.
