Tweco, 11501202, Contact Tip, 15H Series, 0.035 in, 1.97 in; 0.044 in Bore, For Tweco No. 5 MIG Guns

Tweco® 15 Series Heavy Duty Contact Tip accommodates 0.035" wire and is perfect for use with 200 - 500 A Tweco® No.5 MIG guns as well as specific MIG gun series. Contact tip with excellent electrical properties is ideal for use in heavy duty welding application up to 500 A. It features part number and wire diameter for easy identification. 1.97" Contact tip with 5/16"-18 UNC- 2A thread size has 0.044" nominal ID and 0.345" OD. Contact tip is made from extruded or gun-drilled 122 DHP copper alloy and machined from a copper alloy tubing to offer a consistent as well as smooth surface of inside diameter with +/-0.003" tolerance. It has threaded style that ensures proper contact with a gas diffuser when installed to the MIG gun. It comes in slip-on or thread-on nozzle styles with a choice of diameter bore sizes. Contact tip locks in place when twisted and offers better electrical conductivity with increased surface contact. Contact tip features thick-walled design that acts like a heat sink conducting heat away from the arc source. It can be twisted quarter turn clockwise when tip wear point is reached that reveals a new wear point for doubling the life of the tip. Contact tip is sold as 25 per pack.

Applications

• Used in heavy duty welding application up to 500 Amp

Features

• No threads to worry about
• When tip wear point is reached after use, twist it half turn counter-clockwise to expose a new wear point
• Inside diameter tolerance is held to +/-.003 in
• Twist it quarter turn clockwise
• Increases electrical conductive surface area and thereby increases electrical conductivity
