Contact Tip, 0.073" Tip Size, 122 DHP Copper Alloy, 1/16" Wire, 500 amp, 5/16-18 UNC- 2A Connection, 0.345" Outer Dia x 1.59" Length, Threaded Style

Used in standard welding application up to 500 amp Excellent electrical properties Inside diameter tolerance is held to +/-.003 Inch 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 Easy identification - each contact tip is marked showing part no and wire diameter Slip-on or thread-on nozzle styles with a choice of diameter bore sizes Twist-it and forget it-twist it and it locks in place, no threads to worry about Increased surface contact between contact tip/diffuser for better electrical conductivity Double tip life-twist it quarter turn clockwise When tip wear point is reached after use, twist it half turn counter-clockwise to expose a new wear point 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
