Tweco 1140-1247 Contact Tip Heavy Duty 5/64 Inch Mig

Product Description

The TWECO 1140-1247 is a heavy-duty MIG welding contact tip machined from copper alloy tubing. It delivers a consistent and smooth inside diameter surface, holding inside diameter tolerance to plus or minus 0.003 inches for reliable wire feed and arc stability. The threaded style design ensures proper contact with a gas diffuser when installed to the MIG gun. Sized for 5/64 inch wire diameter, this tip is a standard consumable installed by welding technicians and fabricators during routine MIG gun maintenance.

This contact tip is suited for MIG welding applications in fabrication shops, manufacturing environments, and field welding operations. It fits Eliminator style gas diffusers and is compatible with both threaded and twist lock Eliminator style contact tip configurations. Each tip is individually marked with the part number and wire diameter for fast identification during consumable changes, reducing downtime at the gun.

Installation Notes

Contact tips are installed and replaced by welding technicians as part of routine MIG gun consumable maintenance. Power down and de-energize the welding system before removing or installing contact tips. Use the appropriate tip wrench to seat the threaded tip firmly against the gas diffuser without overtightening, which can distort the bore. Inspect the diffuser for wear or spatter buildup before installing a new tip.
