Bernard Welding, an Illinois Tool Works brand, is a leading manufacturer of high-end welding tools. Its extensive catalogue includes MIG welding guns, fume extraction welding guns, MIG welding consumables, Dura-Flux guns and related accessories. Bernard air-cooled MIG welding guns feature an internal gas hose which resists chances of kinking from the consistent gas flow and a rotatable (45 - 60 degrees) aluminium neck tube to withstand abuse and heat dissipation. These semi-automatic welding guns have cone nut threaded cable connections for increased electrical conductivity and are ideal for automotive, manufacturing and metalworking industries. Bernard gas diffusers can be installed easily into cooling / load-lock / transfer / process chambers and are compatible for use with most of the systems. These brass gas diffusers enable expeditious venting to the atmosphere while restricting any other particles from entering into the chamber. Choose from a wide range of these gas diffusers and other company products, such as welding contact tips, adapter heads, insulator caps & liners, on Raptor Supplies.
