The Weldmark® by Tweco® 14 Series Standard Duty Contact Tip accommodates 1/16" (1.6mm) wire and is perfect for use with 200 - 400 A Tweco® No.2, No.3, No.4 MIG gun as well as specific MIG gun series. This contact tip with excellent electrical properties is ideal for use in standard duty welding applications up to 400 A. It features a part number and wire diameter for easy identification. 1 1/2" Contact tip with 1/4"-28 UNF-2A thread size has 0.073" nominal ID and 1/4" OD. The contact tip is made from extruded or gun-drilled 122 DHP copper alloy and machined from a copper alloy tubing to offer a consistent as well as smooth surface of inside diameter with +/-0.003" tolerance. It has a threaded style that ensures proper contact with a gas diffuser when installed to the MIG gun. It also comes in slip-on or thread-on nozzle styles with a choice of diameter bore sizes. The contact tip locks in place when twisted and offers better electrical conductivity with increased surface contact. It features a thick-walled design that acts like a heat sink, conducting heat away from the arc source. It can be twisted a quarter turn clockwise when the tip wear point is reached, revealing a new wear point for doubling the life of the tip. (25 / pack)
