0.035" 16ST Series Heavy Duty Tapered Contact Tip For 350 - 600A No. 6 And Spray Master Series MIG Guns, 25 Per Pack

Easy identification - each contact tip is marked showing part no and wire diameter Excellent electrical properties Inside diameter tolerance is held to +/-.003 in Threaded style contact tip to ensure proper contact with a gas diffuser when installed to the MIG gun Machined from a copper alloy tubing providing a consistent and smooth inside diameter surface Twist it and it locks in place No threads to worry about Increased surface contact between contact tip/diffuser for better electrical conductivity Twist it quarter turn clockwise Use genuine Tweco accessories, parts, and consumables to protect the quality of your welds and the life of your gun 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 conductivityApplications: Used in standard welding application up to 600 Amp
