Tweco 1110-1100 Mig Contact Tip 0.023 in 25 Pack

Product Description

The TWECO 1110-1100 is an 11 Series standard-duty MIG contact tip designed for 0.023-inch wire with a 0.031-inch nominal bore ID and a 1-inch length. Machined from 122 DHP copper alloy tubing, it delivers consistent inside diameter tolerances held to plus or minus 0.003 inches, ensuring reliable arc performance in standard MIG welding applications up to 200 amps. The M6 x 1.0-6g thread size provides solid engagement with compatible gas diffusers. Each tip is marked with the part number and wire diameter for fast identification on the job. Sold in packs of 25.

This contact tip fits the Tweco No. 1 MIG gun rated at 200 amps and is compatible with specific Tweco MIG gun series using the 11 Series consumable platform. It suits standard-duty welding environments in fabrication, maintenance, and repair settings where 0.023-inch solid or flux-core wire is the primary consumable. The slip-on or thread-on nozzle compatibility adds flexibility across compatible gun configurations. The thick-walled copper design manages heat effectively, making this tip a practical choice for sustained production welding cycles.

Key Features

• Machined from extruded or gun-drilled 122 DHP copper alloy for consistent, smooth bore surface
• Inside diameter tolerance held to plus or minus 0.003 inches for reliable wire feed and arc stability
• M6 x 1.0-6g thread style ensures secure engagement with gas diffuser
• Twist-lock design locks tip in place without loose thread concerns
• Quarter-turn clockwise rotation reveals a new wear point, effectively doubling tip service life
• Thick-walled construction acts as a heat sink, conducting heat away from the arc source
• Each tip marked with part number and wire diameter for easy field identification

Compatibility

Designed for use with the 200-amp Tweco No. 1 MIG gun and compatible Tweco MIG gun series that accept 11 Series standard-duty contact tips with M6 x 1.0-6g thread size.

Installation Notes

Contact tip installation and replacement is performed by welding professionals or qualified maintenance technicians. Always power down the MIG welder and allow the gun to cool before replacing contact tips. Thread the tip firmly by hand into the gas diffuser until fully seated, then confirm engagement by the twist-lock mechanism. Inspect the diffuser threads for wear or spatter buildup before installing a new tip.
