The Tweco® Heavy Duty Contact Tip is designed for use with 1/16" wire and is compatible with 200 - 400 A Tweco® No.2, No.3, and No.4 MIG guns. It is specifically engineered for aluminum wire and certain MIG gun series. This contact tip offers exceptional electrical properties, making it ideal for heavy duty welding applications up to 400 A. With its part number and wire diameter clearly marked, it is easy to identify. The contact tip has a 1.47" length, a 1/4"-28 UNF-2A thread size, a 0.082" nominal ID, and a 0.283" OD. It is crafted from extruded or gun-drilled 122 DHP copper alloy and machined from a copper alloy tubing to ensure a consistent and smooth inside diameter with a tolerance of +/-0.003". The threaded style of the contact tip guarantees proper contact with a gas diffuser when installed to the MIG gun. It is available in slip-on or thread-on nozzle styles with various bore sizes to choose from. The contact tip locks securely in place when twisted and offers improved electrical conductivity with increased surface contact. Its thick-walled design acts as a heat sink, effectively dissipating heat away from the arc source. When the tip wear point is reached, simply twist it a quarter turn clockwise to expose a new wear point, effectively doubling the life of the tip. The contact tip is sold in packs of 25. To ensure the quality of your welds and the longevity of your gun, it is recommended to use genuine Tweco® accessories, parts, and consumables.
