The Tweco® 15 Series Heavy Duty Contact Tip is designed to accommodate 0.035" wire and is a perfect match for 200 - 500 A Tweco® No.5 MIG guns and certain MIG gun series. With exceptional electrical properties, this contact tip is ideal for heavy duty welding applications up to 500 A. It is easy to identify, thanks to its part number and wire diameter markings.
This 1.97" contact tip has a 5/16"-18 UNC-2A thread size, a 0.044" nominal ID, and a 0.345" OD. It is constructed 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.
Featuring a slip-on or thread-on nozzle style with varying bore sizes, this contact tip securely locks in place when twisted. This design provides 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, simply twist it a quarter turn clockwise to reveal a new wear point, effectively doubling the life of the tip. Each pack includes 25 contact tips.
Remember to use genuine Tweco® accessories, parts, and consumables to ensure the quality of your welds and prolong the life of your gun.
