Tweco Tapered Contact Tip, 0.052" Wire Diameter, 1.50" Overall Length, 0.375" Outside Diameter, 122 DHP Copper Alloy Material

Tapered contact tip Use with aluminum welding wire Easy identification - Each contact tip is marked showing Part No. and wire diameter Excellent electrical properties Inside diameter tolerance is held to +/-.003" Machined from a copper alloy tubing providing a consistent and smooth inside diameter surface Contact tips manufactured from extruded or gun-drilled copper alloy Contact tips in either threaded and/or twist lock Eliminator style contact tips for Eliminator style gas diffuser Threaded style contact tip to ensure proper contact with a gas diffuser when installed to the MIG gun Used in standard welding application up to 600 amperes Slip-On or Thread-On nozzle styles with a choice of diameter bore sizes Gas diffusers designed for specific MIG gun series Contact tips in either threaded and/or twist lock Eliminator style contact tips for Eliminator style gas diffuser Twist-it and forget ito Twist it and it locks in placeo No threads to worry abouto Increased surface contact between contact tip/diffuser for better electrical conductivity Double tip lifeo Twist it quarter turn clockwiseo When tip wear point is reached after use, twist it half turn counter-clockwise to expose a new wear pointo This doubles the life of the tip Thick-walled diffuser design acts as "heat sink" and conducts heat away from the arc source Increases electrical conductive surface area and thereby increases electrical conductivity
