Tig tungsten
Fortis64:
Advice needed on which tig tungsten in general terms to use on mild steel from light gauge sheet metal to half inch thick plate. Been advised to use 2% lanthanated tungsten . Could you share what grinds you put on them for different styles of welding ,ie...light to heavy beads .

Sounds fine. Pretty steep angle in general. Steeper tends toward narrower hot area. DC reverse is much more penetrating. DC straight is diffuse. The heat goes with the electrons. Flat spot is related to current.
Just internet up a chart to get your electrode size right.
Btw, if you have access to harbor fright saw grinders, buy one!!!! Put on the diamond wheel and revel in moderate speed grinding awesomeness. It does great on tungsten and carbide, and is slow enough for steel (really).

This one?

3800 rpm / 140W?
thank you,

Yep, that's it! I'm 99% sure mine isnt 3800 rpm. I put one in at work too, so I've run two of them. It's a brush motor, so you could drop the speed further by going to half wave rectification of phase control.
If there's interest I could publish my sliding table for it.

There is enough interest for the sliding table. Please, publish something.
