MILLER ELECTRIC TIG Gas Lens & Collet Body

Large-diameter gas lenses are used in TIG torch setups that include a large-diameter gas lens nozzle. They provide more shielding gas coverage to the weld pool than standard gas lenses. Also called gas diffusers, the lenses have mesh screens that reduce turbulence in the shielding gas stream as it is released into a nozzle, which helps ensure the gas is evenly distributed across the weld pool. They are commonly used in TIG welding applications on stainless steel, titanium, and aluminum. Gas lenses also allow the tungsten electrode to stick out of the nozzle further than collet bodies without sacrificing gas coverage, which helps improve the operator's view of the arc and weld pool when welding in tight areas.
