Gas Lens Large for WP17,18,26 Type TIG Torches
Large gas lenses replaces the collet body and standard gas lenses that is standard in most TIG torches, and in conjunction with a collet, it helps to hold the tungsten in place and creates the electrical contact necessary for proper current transfer. It also serves a much more important function, it provides a much larger shielding gas coverage and joint accessibility. TIG torch large gas lenses are available in a range of sizes to suit various tungsten diameters.
When welding material that tends to react to atmospheric contaminants, larger gas lenses provide improved gas coverage.
Large gas lenses reduce shielding gas turbulence and provide longer, undisturbed laminar flow of the gas to the weld pool.
The large gas lens also allows the welder to move the nozzle further away from the joint and extend the tungsten electrode past the nozzle by one inch or more.
The additional electrode extension provides better visibility of the joint and arc, this can improve a welder’s ability to lay a proper weld in critical applications and harder to reach areas such as "T", "K" and "Y" joints.
In some applications, a large gas lens can also help to reduce shielding gas consumption.
Compatible with WP17,18 and 26 type TIG torches with insulators 18CG & 54N63.
