Thread: SA TIG Tungstens Free

Handful of Red and White tipped TIG electrodes to rehome.

Asstd 2.4 and 3.2mm, some used, some never ground.
Surplus to requirements, I’ve standardised on Lanthanated for everything.
Free to a good home, will post but can’t do so for a week or so because of work commitments.

Offered as a lot only, not separating.

I would like these. I'll PM you with details. Thanks, Max.

Dear Mr High Speed Juvenile Frog.

Not that I want them, but could you explain how (the technology) and where these are used please. I always thought that tungsten tips were inserts fitted into the handpiece. I am a bit out of date as I have not engaged in TIG welding for at least 35 years. Perhaps a post in the "Welding" area of the forum would help us "old kodgers!"

Thanks,
Alan.

The link below has a diagram that shows the assembly and where the tungsten fits into the torch about halfway down the page.

Essentially the tungsten is one side of the electrical connection of the welding process. Tungsten is the weapon of choice for this component because it is both conductive to electricity, and has a melting point higher than anything you can use it to weld. Different coloured bands are used to discriminate the different treatments applied to the raw tungsten to make it perform better under a certain application. In this case the white banded ones are Zirconiated (the tungsten has been treated with zirconia), and the Red banded ones are Thoriated (treated with very small doses of radioactive Thorium). The Zirconiated tungstens are used for AC welding of aluminium, and the Thoriated are used for DC welding of steel. I use Lanthanated now which is suitable for both. Using an AC/DC capable tungsten means I don't have to remember off the top of my head, which one is for which application (they perform poorly if you guess and get it wrong).

Hope that helps

The way that I remember which is for what, is that white is close to Aluminium color, plus the A for Ally is your polarity, and the red is close to rusty steel.

You can use the Red thoriated tungstens for welding aluminium too.
