Tweco 1110-1302 Mig Contact Tip 0.035 in 25 Pack

Product Description

The TWECO 1110-1302 is a standard-duty tapered MIG contact tip designed for 0.035-inch wire diameter. Machined from extruded or gun-drilled 122 DHP copper alloy tubing, it delivers a consistent, smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The nominal bore ID is 0.044 inches, the OD is 0.25 inches, and the overall length is 1 inch. Thread size is M6 x 1.0-6g. Rated for standard welding applications up to 200 amps, this tip features a thick-walled design that acts as a heat sink, drawing heat away from the arc source. Each tip is marked with the part number and wire diameter for fast identification on the job. Sold in a pack of 25.

This contact tip is designed for use in standard MIG welding applications up to 200 amps. It is compatible with Tweco Spray Master guns rated 160 to 250 amps, the Tweco Mini MIG Gun, and Tweco No. 1 MIG Guns. The tip installs into a gas diffuser using a threaded style connection that ensures solid electrical contact. It is also available in slip-on or thread-on nozzle configurations. A licensed welder or experienced MIG gun technician typically handles installation during routine consumable replacement on the shop floor or in the field.

Key Features

• 0.035-inch wire diameter, 0.044-inch nominal bore ID, 0.25-inch OD, 1-inch length
• Machined from 122 DHP copper alloy for consistent bore surface and excellent electrical conductivity
• ID tolerance held to plus or minus 0.003 inches for reliable wire feed
• Thick-walled construction acts as a heat sink to conduct heat away from the arc
• Twist-lock design exposes a new wear point when the original wear point is reached, effectively doubling tip service life
• Each tip is marked with part number and wire diameter for quick identification
• M6 x 1.0-6g thread ensures secure, consistent gas diffuser contact

Compatibility

Compatible with Tweco Spray Master MIG Guns rated 160 to 250 amps, Tweco Mini MIG Gun, and Tweco No. 1 MIG Guns. Suitable for slip-on or thread-on nozzle configurations with an M6 x 1.0-6g threaded gas diffuser.

Installation Notes

Installation is performed by a welder or MIG gun technician as part of routine consumable replacement. Always disconnect or power down the welding machine and allow the gun to cool before removing a worn contact tip. Use the correct tip wrench to avoid damaging the M6 threads on the diffuser. Do not overtighten — hand-snug plus a fraction of a turn is standard practice for threaded MIG consumables.
