Tweco® 14 Series Standard Duty Tapered Contact Tip accommodates 0.04" wire and is perfect for use with 200 - 400 A Tweco® No.2, No.3, No.4 MIG guns. Contact tip with excellent electrical properties is ideal for use in standard welding application up to 400 A. It features part number and wire diameter for easy identification. 1 1/2" Contact tip with 1/4"-28 UNF-2A thread size has 0.048" nominal ID and 1/4" OD. Contact tip is made from 122 DHP copper alloys 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. Contact tip is sold as 25 per pack.
Features
Easy identification - each contact tip is marked showing part no and wire diameter
Excellent electrical properties
Inside diameter tolerance is held to +/-.003 in
Threaded style contact tip to ensure proper contact with a gas diffuser when installed to the MIG gun
Machined from a copper alloy tubing providing a consistent and smooth inside diameter surface
Twist it and it locks in place
No threads to worry about
Increased surface contact between contact tip/diffuser for better electrical conductivity twist it quarter turn clockwise
When tip wear point is reached after use, twist it half turn counter-clockwise to expose a new wear point
This doubles the life of the tip
Thick-walled diffuser design acts as a heat sink and conducts heat away from the arc source
Increases electrical conductive surface area and thereby increases electrical conductivity
Applications
Used in standard welding application up to 400 Amp
