TECH: Make a cheap tig tungsten grinder

[bwagner]

I thought you could lick the new orange banded shit? thats what I use on everything.

-A.

I've actually started using the 2% Lanthanated on recommendation from the "Welding tips and tricks" website.....best choice I've made since buying my Dynasty. Not the readily available 1.5% ones, they actually deteriorate rather quickly. I really recommend them to anyone who does both Aluminum and steel welding.....they keep a nice point for a long time, even when welding with AC........

Why the speed-control box? It's in the pic, but not mentioned in the write-up. Can you not just run the angle-grinder at normal speed?

You can run the angle grinder at full speed, I just find it nice to be able to dial it down a bit for tip grinding control.

Another tip from a welder, always rotate the tungsten in the same direction when sharpening. Sounds minimal, but a swirling pattern of grinding on the tip will affect the characteristics of your arc

What besides aluminum are you using AC for?

We had to weld coupons for high pressure steam black iron tests, TIG the root and cover for 4 or 5 passes .We always brought our Tungsten to a sharp point,the welder dude that was overseeing the testing told us that we should be blunting our tips.
