The Tweco® Heavy Duty Contact Tip is designed to accommodate 0.035" wire and is compatible with 200 - 400 A Tweco® No.2, No.3, and No.4 MIG guns, as well as specific MIG gun series. This contact tip is perfect for heavy duty welding applications up to 400 A, offering excellent electrical properties. Its part number and wire diameter are easily identifiable.
With a 1.47" length and 1/4"-28 UNF-2A thread size, this contact tip has a nominal ID of 0.044" and an OD of 0.283". It is made from extruded or gun-drilled 122 DHP copper alloy and machined from a copper alloy tubing, ensuring a consistent and smooth inside diameter surface with a tolerance of +/-0.003". The threaded style ensures proper contact with a gas diffuser when installed to the MIG gun.
The contact tip is available in slip-on or thread-on nozzle styles, with various diameter bore sizes to choose from. When twisted, it locks in place, providing better electrical conductivity through increased surface contact. Its thick-walled design acts as a heat sink, effectively conducting heat away from the arc source.
For extended tip life, simply twist the contact tip quarter turn clockwise when the wear point is reached, revealing a new wear point and doubling the tip's lifespan. Each pack contains 25 contact tips, and easy identification is facilitated by markings indicating the part number and wire diameter.
By using genuine Tweco® accessories, parts, and consumables, you can protect the quality of your welds and prolong the life of your gun.
