TIG Cup basics

A TIG cup is sometimes called a "tig nozzle".

Welding Sales people or engineers might call it a nozzle but experienced welders call it a "TIG cup".

Standard pink ceramic tig cups are usually what come with a tig torch or tig welding machine...and the torch is usually a 17 style air cooled torch.

Standard tig cups thread onto something called a standard collet body.

There are also gas lens style tig cups that use a gas lens collet body with fine mesh diffuser screens that provide a smoother less turbulent flow of shielding gas.

What are glass TIG cups used for?

Glass tig cups are used for better visibility.

Not necessarily because of being able to see the arc and puddle right thru the cup, but more because a clear cup is like a light bulb that lights the path of the weld making it easier to see.

I personally started using clear glass tig cups for filming the arc.

we can all see what is going on better than with pink ceramic cups.

But I soon learned that clear cups help me see where I am going better.

With larger cups and longer stick outs, this becomes less of a a factor and I typically use ceramic cups.

 

What are Pyrex cups used for in TIG welding?

Pyrex is a trademarked brand of Corning and the terms "Pyrex" and

"Borosilicate glass" are often used interchangably.

Pyrex cups can be used for tig welding applications where seeing better is important. (personally, I can usually see much better with a clear cup)

Pyrex cups are not suited well for walking the cup but work very well for certain situations like welding into corners.

Why are TIG welding cups pink?

TIG welding cups are pink because factories add a pink color.

Alumina cups are naturally white but have been colored pink for a long time now.

Some newer specialty cups like furick ceramic jazzy 10, fupa 12, and moose knuckle 14 are white ceramic.
