The Tweco® 14 Series Standard Duty Contact Tip is designed for use with 0.045" wire and is compatible with 200 - 400 A Tweco® No.2, No.3, No.4 MIG guns, as well as certain MIG gun series. This contact tip is ideal for standard welding applications up to 400 A and offers excellent electrical properties. It is easy to identify with its part number and wire diameter markings. The contact tip has a 1 1/2" length and a 1/4"-28 UNF-2A thread size, with a 0.054" nominal ID and 1/4" OD. Made from extruded or gun-drilled 122 DHP copper alloy, it is carefully machined from a copper alloy tubing to ensure a consistent and smooth inside diameter surface with a tolerance of +/-0.003". This threaded-style contact tip guarantees proper contact with a gas diffuser when installed on the MIG gun and is available in slip-on or thread-on nozzle styles with various bore sizes. It securely locks in place when twisted and offers enhanced electrical conductivity with increased surface contact. The contact tip has a thick-walled design that acts as a heat sink, effectively dissipating heat away from the arc source. When the tip wear point is reached, it can be easily twisted a quarter turn clockwise to reveal a fresh wear point, effectively doubling the life of the tip. Sold in packs of 25, this contact tip ensures easy identification with its marked part number and wire diameter. It is important to use genuine Tweco® accessories, parts, and consumables to maintain the quality of your welds and the lifespan of your MIG gun.
