The Tweco® Heavy Duty Contact Tip is specifically designed to work with 0.045" wire and is compatible with the 200 - 400 A Tweco® No.2, No.3, and No.4 MIG guns, as well as certain MIG gun series. Built for heavy duty welding applications up to 400 A, this contact tip offers exceptional electrical properties. Its part number and wire diameter are clearly marked for easy identification. With a 1.47" size, 1/4"-28 UNF-2A thread, and 0.054" nominal ID, this contact tip is constructed from extruded or gun-drilled 122 DHP copper alloy. Machined from a copper alloy tubing, it provides consistent and smooth inside diameter surface with a +/-0.003" tolerance. The threaded style ensures proper contact with the gas diffuser when installed to the MIG gun. Available in slip-on or thread-on nozzle styles, you can choose a diameter bore size that suits your needs. The contact tip securely locks in place when twisted, offering better electrical conductivity and increased surface contact. Its thick-walled design acts as a heat sink, effectively conducting heat away from the arc source. When the tip wear point is reached, a simple quarter turn clockwise reveals a new wear point, effectively doubling the life of the tip. Each pack contains 25 contact tips. Use genuine Tweco® accessories, parts, and consumables to ensure the quality of your welds and the longevity of your gun.
