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 a Lincoln Square Wave TIG 175 and the min. amp setting is 12 amps AC
or DC.  If the setting is adjusted to any setting above 12 amps the amperage
is variable by pedal from 12 amps to that setting. Great machine but still
practicing.
