Tweco 1160-1441 Mig Contact Tip 0.045 in 25 Pack

Product Description

The TWECO 1160-1441 is a tapered MIG contact tip designed for 0.045 inch wire diameter and rated for heavy-duty welding applications up to 600 amps. Machined from 122 DHP copper alloy tubing, the tip features a 0.054 inch nominal bore ID with a tight plus or minus 0.003 inch tolerance, delivering consistent current transfer and a smooth wire feed surface. At 1.5 inches in length with a 0.375 inch OD and M8 x 1.25-6g thread, this tip threads directly onto compatible gas diffusers in standard MIG gun configurations. Sold in packs of 25, making it practical for shop stock or field kits.

This contact tip is suited for industrial and fabrication environments where high-amperage MIG welding is routine. The threaded style ensures solid contact with the gas diffuser, reducing arc instability caused by poor tip seating. Each tip is marked with the part number and wire diameter for fast identification during tip changes on the gun. It fits standard MIG setups running 0.045 inch solid or flux-core wire in both production and maintenance welding scenarios.

Compatibility

Designed as an OEM-style replacement contact tip for standard MIG guns accepting M8 x 1.25-6g threaded tips with a 0.375 inch OD and 1.5 inch length, suitable for 0.045 inch wire diameter applications.

Installation Notes

Contact tips are installed and serviced by welding technicians as routine consumable maintenance on MIG guns. Power down the welder and allow the gun neck to cool before removing a spent tip. Use the appropriate tip wrench or pliers to thread the new tip snugly into the gas diffuser — do not overtighten, as this can distort the bore or damage diffuser threads. Inspect the diffuser for spatter buildup before installing a new tip.
