Tregaskiss 401-6 Series Nozzles are heavy-duty (HD), air-cooled nozzles designed to be durable and long-lasting for MIG welding applications. Made from hard-drawn copper, these nozzles have a tapered shape and are engineered with a smooth surface finish and rounded edges to help minimize weld spatter buildup. They are a slip-on style nozzle and are intended for use with the TOUGH LOCK® Diffuser 404-32 (for robotic applications) or 404-26 (for semi-automatic applications).
