Gas Lenses


Gas lenses are used to provide a laminar flow of shielding gas. All These attachments have a porous barrier diffuser and are fitted around the electrode or collet and remain inside the nozzles. By the gas lenses it is possible to keep longer gap between the nozzle and the work piece and to weld joints with limited accessibility providing adequate shielding.
