Tweco 1160-1114 Mig Contact Tip 0.062 in 600A Heavy Duty

Product Description

The TWECO 1160-1114 is a 16 Series Standard Heavy Duty MIG contact tip rated for welding applications up to 600 amps. Designed for 0.062 inch wire, it features a 0.082 inch nominal bore ID and a 0.375 inch OD, with an overall length of 1.5 inches and an M8 x 1.25-6g thread size. The tip is machined from extruded or gun-drilled 122 DHP copper alloy tubing, delivering a consistent, smooth inside diameter held to a tolerance of plus or minus 0.003 inches. Licensed welding technicians and MIG gun service professionals install this tip as a direct consumable replacement in high-amperage industrial and fabrication environments.

This contact tip is suited for heavy-duty MIG welding on aluminum wire in industrial and fabrication settings. It is compatible with Tweco Spray Master MIG guns rated 350 to 600 amps and Tweco No. 6 MIG guns. The threaded style ensures proper seating against the gas diffuser, and the tip is available in slip-on or thread-on nozzle configurations. Each tip is marked with its part number and wire diameter for quick field identification, reducing downtime during changeover.
