Tweco 1110-1301 Mig Contact Tip 0.030 in 0.038 Bore 25 Pack

Product Description

The TWECO 1110-1301 is a standard-duty tapered MIG contact tip designed for 0.030 inch wire diameter and featuring a 0.038 inch nominal bore ID. Built from extruded or gun-drilled 122 DHP copper alloy and machined from copper alloy tubing, it delivers a consistent, smooth inside diameter held to a tolerance of plus or minus 0.003 inches. The 1 inch tip uses an M6 x 1.0-6g thread size with a 1/4 inch OD. Rated for standard welding applications up to 200 amps, it is installed by licensed welders and MIG gun service technicians. Each tip is marked with the part number and wire diameter for quick field identification. Sold in packs of 25.

This contact tip is suited for standard MIG welding applications up to 200 amps in residential, light industrial, and fabrication environments. It is compatible with 160 to 250 amp Tweco Spray Master guns, Tweco Mini MIG guns, and Tweco No. 1 MIG guns. The threaded style ensures proper seating against the gas diffuser. The tip is available in slip-on or thread-on nozzle configurations, giving technicians flexibility across common gun setups.

Key Features

• 122 DHP copper alloy construction provides strong electrical conductivity and consistent bore surface finish
• Inside diameter tolerance held to plus or minus 0.003 inches for reliable wire feed
• Twist-lock design seats the tip securely against the gas diffuser without thread engagement concerns
• Quarter-turn clockwise rotation reveals a new wear point, effectively doubling usable tip life
• Thick-walled design acts as a heat sink, conducting heat away from the arc source
• Each tip stamped with part number and wire diameter for fast identification in the field
• Sold as 25 per pack for job-site and shop stock needs

Compatibility

Compatible with 160 to 250 amp Tweco Spray Master guns, Tweco Mini MIG guns, and Tweco No. 1 MIG guns. Designed for use with slip-on or thread-on nozzle styles and standard gas diffusers on these platforms.

Installation Notes

Installation is performed by a qualified welder or MIG gun technician. Always de-energize the welder and allow the gun neck to cool before replacing contact tips. Use the appropriate tip wrench or pliers to seat the threaded tip fully against the gas diffuser, and confirm the twist-lock engagement before resuming operation. Do not over-tighten, as this can deform the bore and affect wire feed consistency.
