TIG Torch Gas Diffusers

Smooth the flow of shielding gas coming out of your TIG torch nozzle, so you have more control and less waste. These mesh diffusers reduce turbulence so that the gas stays where you need it, shielding the weld and preventing oxidation and pitting, which cause weak welds.

Diffusers for ceramic nozzles are commonly called gas lenses.

TIG Torch Insulators

For Ceramic Nozzles

For Borosilicate Glass Nozzles

Prevent shielding gas from escaping and protect torch components from excessive heat—these insulators form a seal between nozzle and torch. Choose an insulator that works with your torch’s series number and nozzle’s material.
