A friend has a small Lincoln Tig.  The problem is that it does not
regulate below 30 amps no matter what you do with the foot pedal.   30
amps is minimun.   Not practical on .035 4130.  The larger welders
(250amp) will work right down to zero amps.   Jerry

I have six welding/cutting machines, (four of which are Lincoln).
and as far as brands are concerned, I have been most pleased
with Lincoln.

I checked with Lincoln at Copper State and they denied it.
The hotshot welder there was able to weld aluminum foil.
In fact I bought a 175 amp tig so I will let you know.
