I'm not able explain all its subtle differences.  My analysis is that it

works fine, but I will still choose to go with TIG about

95% of the time.

Thanks for the description Mark. I have done a lot of
torch braizing on race car chassis. (safer than welding
usually) I like both my torches and the syncrowave!
What should be mentioned about TIG is that using the
inert gas can prevent inclusions in, and oxidation of,
the weld. Important on some alloys of both steel and
aluminum. Bill Jepson

Good point Bill.  One other thing in TIG's favor is more concentrated heat
transfer resulting in less warpage.  With a foot pedal you have full
control of amps (heat), allowing maximum control of puddle size.   Mark S.
