Xtrweld 11-40 Contact Tip 0.040 Inch Tweco Style 11

Product Description

The XTRWELD 11-40 is a standard contact tip designed for MIG welding guns that use 0.040 inch diameter wire. Built to Tweco Style 11 Series dimensions, this tip fits a range of 100A to 160A MIG guns commonly used in fabrication, maintenance, and production welding. The tip transfers welding current to the wire at the point of contact and directly affects arc stability and weld quality. It is marked with its part number and size for fast identification during consumable changes. Welding technicians and fabricators install and replace contact tips as routine maintenance to maintain consistent weld performance.

This contact tip is suited for light-duty to medium-duty MIG welding applications including structural tacking, sheet metal work, and general fabrication. It fits Tweco-style MIG guns in the 100A to 160A range, including the Classic Weldskill and Mini-MIG platforms. The 0.040 inch bore size matches standard 0.040 inch MIG wire, maintaining proper electrical contact and minimizing wire burnback. It is sold as a pack and is intended for jobsite use where consumables need to be swapped quickly without special tooling.

Installation Notes

Contact tip replacement is performed by welding technicians as part of routine gun maintenance. Always power down the welder and allow the gun to cool before removing the worn tip. Use a contact tip wrench or slip-joint pliers to remove and seat the tip — do not overtighten, as this can distort the bore and cause wire feed issues. Inspect the gas diffuser and nozzle for spatter buildup during each tip change.
