The precision gas lens nozzle for LightWELD enhances flow through the head while minimizing system backpressure, which results in homogenous gas flow across the nozzle with no increase in supply gas pressure. The gas lens purge nozzle is ideal for welders seeking to improve gas shielding performance when welding materials sensitive to oxygen, moisture, or other vapors or gases that may be present in the atmosphere. Such gases can combine with stainless and duplex steels as well as titanium, nickel and zirconium alloys forming undesirable compounds that may lead to excessive oxidation or structural defects in the weld joint.
