Tweco 1110-1213 Mig Contact Tip 3/64 Inch 25 Pack

Product Description

The TWECO 1110-1213 is a heavy-duty MIG contact tip designed for demanding welding environments. Built from extruded or gun-drilled 122 DHP copper alloy and machined from copper alloy tubing, it delivers a consistent, smooth inside diameter surface held to a tolerance of +/- 0.003 inches. The thick-walled design acts as a heat sink, drawing heat away from the arc source to extend service life. Rated for welding applications up to 300 amps, this tip accommodates 3/64-inch wire and is sold in packs of 25. Licensed welding professionals and fabricators rely on this tip for consistent electrical conductivity and reduced downtime.

This contact tip is suited for heavy-duty MIG welding in both shop and production environments. It is compatible with 160 to 250 amp Tweco No. 1 MIG guns as well as specific MIG gun series that accept this tip style. The threaded-style design ensures proper contact with the gas diffuser when installed. Each tip is individually marked with the part number and wire diameter for quick identification during changeovers. Available with slip-on or thread-on nozzle styles and a choice of bore diameter sizes to match the application.

Key Features

• Machined from 122 DHP copper alloy for excellent electrical conductivity and heat dissipation
• Inside diameter tolerance held to +/- 0.003 inches for consistent wire feed
• Twist-lock design — quarter turn clockwise locks tip in place; no threads required at the nozzle interface
• Extended tip life: rotate a quarter turn clockwise at first wear point to expose a second wear surface, effectively doubling usable life
• Thick-walled construction acts as a heat sink, conducting heat away from the arc source
• Each tip is marked with part number and wire diameter for fast field identification
• Compatible with slip-on and thread-on nozzle styles

Compatibility

Designed for use with 160 to 250 amp Tweco No. 1 MIG guns and compatible MIG gun series that accept a 3/64-inch bore threaded contact tip.

Installation Notes

Contact tip installation and replacement should be performed by a qualified welding technician with the power source switched off and the MIG gun fully cooled. Use appropriate insulated gloves and tip removal tools to avoid burns from residual heat. Ensure the gas diffuser threads are clean and undamaged before installing the new tip to maintain proper electrical contact. Follow the gun manufacturer's service guidelines and applicable AWS safety standards during consumable replacement.
