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
• Use genuine Tweco® accessories, parts, and consumables to protect the quality of your welds and the life of your gun
• 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 -heat sink and conducts heat away from the arc source
• Increases electrical conductive surface area and thereby increases electrical conductivity
