Bobcat 250-scratch start tig

What size tungsten, and what amp ranges do I use for scratch start tig using a Bobcat 250? I have never tig welded with an engine driven machine before-looking for some info to get started.


----------------------------------------------------

generally, if you are under 200 amps, a 3/32 tungsten will be fine.

there is a lot of overlap where either a 3/32 or 1//8 will work equally good.
