Frequently Asked Questions

What makes the Shorty Series different?
The Shorty Series uses a compact overall profile for improved access and torch maneuverability.

What does the EDGE Diffuser do?
It smooths and distributes shielding gas more evenly for improved weld protection.

Why use a glass cup?
Glass cups provide improved visibility of the weld puddle and surrounding joint area.

Can this support extended tungsten stick-out?
Yes. The large shielding area helps maintain proper gas coverage with longer tungsten extension.

What sizes are available?
This cup is available for 3/32", 1/8", and 5/32" tungsten setups.
