Gas lens?

Yeah his post gave me the impression he was saying that you could stick it out farther with a regular collet body. I have stuck the electrode out over an inch to get into tight places before.

Even though they are bigger sometimes depending on the place you trying weld you can extend the tungsten out about and inch with a oversized cup. You can see it done here. http://www.weldingtipsandtricks.com/...eel-parts.html

Good to see someone else who uses that sight. I subscribe to their videos to get my "fix" of welding every week.

You can stick the electrode out farther with a gas lens since it directs argon out of the torch in a smooth straight column... gas lens on right><picture from CK Worldwide.

A picture is worth a thousand words!

With the #12 you need to use some kind of diffuser. A stainless screen, chore boy, or a scotch brite pad. I like to screen the best but all of them suck when you are putting in the tungsten you have to be careful it doesn't move.
