Zir W- is the way to go for AC aluminum tig

[rb455ho]

HAWK, I did several 1/2" 6061-T6 with the 1/8" Zir-W electrode and it works great. I can set the balance control high for a narrow more penetrating bead and low for a wider one. Why would anyone ever use pure Z when this is available?

Thanks for the great info.

Rob,

A lot of professional guys running the Sync 350's at the aircraft plants do use Zirtung. That is where I learned about it. I don't think the general welding public is aware of it. I know first hand it will make a new machine out of your Syncrowave on AC!

I use a Dynasty with 2% lanthanated for my Al work. However, if I still owned a squarewave machine the Zirc would be king of the tungsten hill. Get some 2% lanthanated sharpened to a point for your DC work. You are welcome and enjoy.

Merry Christmas!!!

2% lanthanated

HAWK, your friends at diamond ground are sending me some samples as I requested. I will email them and see if they will include some 2% lan. This weekend I am going to try my syn180 at home with the Zir-W. I will let you know how the rebirth goes.

Rob,

Too cool. Don't expect miracles as you are now seriously spoiled by the Sync 350!

We teach all our students at the Hobart institute on zirtung on aluminum. It is great stuff for the transformer type power sources. I wish everyone could try it I don't think they would go back to the pure tungsten. Take care.

I know I will never purchase pure W again. I really enjoy this forum guys. All of you are very knowledgable and friendly. I wish all of you Happy Holidays!!
