The Tweco® 11 Series Heavy Duty Contact Tip is designed to accommodate 0.045" wire and is compatible with the 160 - 250 A Tweco® No.1 MIG gun, as well as certain MIG gun series. This contact tip has exceptional electrical properties, making it ideal for heavy-duty welding applications up to 200 A. It is easily identifiable with its part number and wire diameter. The contact tip has a 1" length and features an M6 X 1.0-6g thread size, with a nominal inside diameter of 0.054" and an outside diameter of 0.283".
Made from high-quality 122 DHP copper alloy, the contact tip is constructed through extrusion or gun-drilling methods, ensuring a consistent and smooth inside diameter surface with a tolerance of +/-0.003". Its threaded style guarantees proper contact with a gas diffuser when installed into the MIG gun. It is available in slip-on or thread-on nozzle styles, with various diameter bore size options.
The contact tip securely locks in place when twisted, providing better electrical conductivity and increased surface contact. Additionally, its thick-walled design acts as a heat sink, effectively conducting heat away from the arc source. When the tip wear point is reached, the contact tip can be twisted a quarter turn clockwise to reveal a new wear point, effectively doubling its lifespan.
Sold in packs of 25, each contact tip is clearly marked with its part number and wire diameter for easy identification. It is recommended to use genuine Tweco® accessories, parts, and consumables to ensure the quality of your welds and prolong the lifespan of your MIG gun.
