Tweco 1110-1102 Mig Contact Tip 0.035 in 200A 25-pack

Product Description

The TWECO 1110-1102 is a standard-duty MIG contact tip designed for 0.035-inch welding wire with a 0.044-inch nominal bore ID. Machined from 122 DHP copper alloy tubing, the tip delivers consistent electrical conductivity and a smooth inside-diameter surface held to a +/- 0.003-inch tolerance. The 1-inch length and M6 x 1.0-6g thread size make it a direct fit for the Tweco No. 1 MIG gun platform. Rated for welding applications up to 200 amps, it features a thick-walled construction that acts as a heat sink, drawing heat away from the arc source. Sold in packs of 25.

This contact tip is suited for standard MIG welding applications in fabrication, maintenance, and repair environments up to 200 amps. The threaded style ensures positive contact with the gas diffuser when installed. It is compatible with slip-on and thread-on nozzle configurations. Each tip is marked with the part number and wire diameter for fast identification during tip changes, minimizing downtime in production welding settings. The quarter-turn twist mechanism locks the tip in place and allows the operator to expose a fresh wear point by rotating the tip, effectively doubling service life before replacement is needed.

Key Features

• 0.035-inch wire size with 0.044-inch nominal bore ID, tolerance held to +/- 0.003 inches
• Machined from 122 DHP extruded or gun-drilled copper alloy tubing for a consistent, smooth ID surface
• Thick-walled design acts as a heat sink to conduct heat away from the arc source
• Twist-lock mechanism: quarter-turn clockwise locks tip in place; half-turn counter-clockwise exposes a new wear point to double tip life
• M6 x 1.0-6g thread ensures secure, proper contact with gas diffuser
• Each tip marked with part number and wire diameter for easy field identification
• Compatible with slip-on and thread-on nozzle styles

Compatibility

Designed for use with the Tweco No. 1 MIG gun rated at 200 amps and compatible MIG gun series that accept M6 x 1.0-6g threaded contact tips with a 1/4-inch OD.

Installation Notes

Contact tip installation and replacement is performed by a qualified welding technician or MIG gun operator. Always power down the welder and disconnect the gun from the power source before replacing the contact tip. Use the appropriate tip wrench to avoid overtightening, which can distort the bore and degrade electrical contact. Inspect the gas diffuser seating surface for spatter buildup before installing a new tip to ensure proper conductivity.
