Looking at some online TIG consumable sellers web sites it seems I can buy
TIG tungstens alloyed to make a universal electrode? I am new to TIG,
having just bought a used Migatronic MTE220. I have received red and white
banded electrodes, but I now wonder if the "grey" banded ones would allow
me to weld aluminium ally, stainless steel and mild steel without buying
several types of tungstens? I will be mainly doing light work on race car
chassis and plumbing / exhausts. Gas will be pure argon, not a mix. Thanks.

Oh, yeah, web sellers. I have bought a bunch of stuff from aglevtech,
and he has been very good about everything. Prices on eBay vary
depending on who is bidding against you, but he is good about delivering
the stuff even if it closes cheap.
