IF your welder does advanced squarewave (AC balance) then if you make

That having been said I own a DC Machine so confirmation would be good
Anything DC i've done fine with 2% thoriated (Red)

I have lanthanated electrodes (anyone needs 3/16" electrodes?) and
they are billed as pretty much universal, they can do steel and
aluminum, AC or DC.

Correct. Gray or Gold banding. Lanthanated tungstens are rated for
AC/DC and are just about as close to universal as can be. Stainless
steel, Alum etc etc etc.

I understand that 2% is marginally better than 1.5% for alum..but most
serious welders will use the slightly cheaper 1.5%.

I have 2% blue ones.

Ive been collecting and using tungstens for a while..and while I
started out using pure (green) tunstens for alum, Ive pretty much
switched to the Lanthanated for just about everything. If its rough
work..Ill use the reds, cause I scored "several" boxes of various
sizes..from .040- 3/16"

That's great!

I love tungsten, it is so heavy and hard.

Thats what my girl friend says about me...

off in job lots is hardly empire building, particularly when you give
them self determination under "play nice" rules.
