Tweco 1160-1440 Mig Contact Tip 0.035 in 25 Pack

Product Description

The TWECO 1160-1440 is a tapered MIG contact tip engineered for standard and heavy-duty welding applications up to 600 amps. Designed to accommodate 0.035-inch wire, this tip features a 0.044-inch nominal inside diameter and a 0.375-inch outside diameter. It measures 1.5 inches in length and threads into the MIG gun gas diffuser using an M8 x 1.25-6g thread. Machined from 122 DHP copper alloy tubing, the inside bore is held to a tolerance of plus or minus 0.003 inches, delivering consistent arc stability and smooth wire feed. The part number and wire diameter are rolled-stamped on the outer surface for fast field identification. Sold in packs of 25.

The 1160-1440 contact tip is suited for professional MIG welding operations in fabrication shops, manufacturing environments, and field welding scenarios where high-amperage output is required. The threaded design ensures a secure, positive connection with the gas diffuser, making it appropriate for continuous-duty cycles and demanding production welding. The 122 DHP copper alloy construction supports excellent electrical conductivity across the full rated capacity. This tip is a practical consumable choice for welders running solid wire in both semi-automatic and automated MIG setups.

Installation Notes

Contact tip installation and replacement should be performed by a qualified welder or welding technician with the MIG gun powered down and the wire feeder disabled. Allow the gun to cool before handling consumables. Thread the tip into the gas diffuser by hand first to avoid cross-threading, then snug with pliers or a contact tip tool — do not overtighten. Inspect the bore for wear or deformation at regular intervals and replace when wire feed becomes erratic or arc quality degrades.
