Tweco 1140-1341 Tapered Contact Tip 0.030 Inch Mig

Product Description

The TWECO 1140-1341 is a tapered contact tip designed for MIG welding guns, machined from copper alloy tubing to deliver a consistent and smooth inside diameter surface. The inside diameter tolerance is held to plus or minus 0.003 inches, ensuring reliable wire feed and stable arc performance. Sized for 0.030-inch wire diameter, this tip is threaded for secure engagement with a compatible gas diffuser. Each tip is clearly marked with the part number and wire diameter for fast identification on the job. Licensed welding technicians and professional fabricators install this tip as a routine consumable replacement during MIG gun maintenance.

This contact tip is suited for use with Eliminator-style gas diffusers on TWECO MIG welding guns. It fits applications in light fabrication, maintenance and repair, and production welding environments where 0.030-inch solid or flux-core wire is in use. The threaded installation style ensures proper contact between the tip and the gas diffuser, maintaining consistent shielding gas flow and electrical conductivity at the arc zone.

Key Features

• Machined from copper alloy tubing for excellent electrical conductivity and consistent bore surface
• Inside diameter tolerance held to plus or minus 0.003 inches for precise wire guidance
• Tapered profile sized for 0.030-inch welding wire diameter
• Threaded style design ensures secure, proper contact with Eliminator-style gas diffuser
• Each tip is marked with part number and wire diameter for easy field identification

Compatibility

Designed for use with Eliminator-style gas diffusers on TWECO MIG welding guns accepting threaded contact tips for 0.030-inch wire diameter.

Installation Notes

Contact tip replacement is performed by qualified welding technicians as part of routine MIG gun consumable maintenance. Always disconnect or power down the welding machine before removing or installing contact tips. Thread the tip in by hand first to avoid cross-threading, then snug with a proper contact tip wrench — do not overtighten. Inspect the gas diffuser seating surface for wear or spatter buildup before installing a new tip.
