Tungsten types ?

[TD2593]

Ive played around with different tungstens with my 250EX, 2% thorated, 1.5% Lanthinated, and 2% Lanthinated. Im seeing issues with the thorated hard starting arc on aluminum is this common with a inverter machine ? With the 1.5 lanthinated I do not have problems unless I stop welding for a few minutes then the arc is somewhat hard starting, the 2% lanthinated is much much better than the other two and holds its tip really well. What are you guys using ?

2% lanthinated for everything. I order from this guy http://myworld.ebay.com/tungsten-dir...id=p4340.l2559

If you are having problems with thoriated, I'd say you are using to much EP or its low quality. Otherwise its a great choice. Most people consider 1.5% Lanthanated to be better at holding up.

I use Pure Tungsten on Aluminum...just seems to be smoother for me.
I've tried the 2% Lanthinate but it contaminates the weld on me!?!?

Have you seen the review on "welding tips and tricks" about all the Tungstens? I'll post it if I can find a link

DONT use PURE on an Inverter. It isn't smoother. Its more erratic.

I have only tried the 2% Lanthinate and the pure. The pure welds like butter and is a pleasure.
The 2% Lanthinated I could watch it spit crap in the weld. So do I go by the old saying "If it ain't broke don't fix it" or should I change to a different Tungsten?

This was my last Aluminum weld with the 250EX and Pure ...
