Tweco 1160-1110 Mig Contact Tip 0.093in Wire 600A Heavy Duty

Product Description

The TWECO 1160-1110 is a 16 Series Standard Heavy Duty MIG contact tip designed for high-amperage welding up to 600 amps. Built from extruded or gun-drilled 122 DHP copper alloy and machined from copper alloy tubing, it delivers a consistent, smooth bore with an inside diameter tolerance of plus or minus 0.003 inches. The tip measures 1.5 inches in length with a 0.106-inch nominal bore, accepts 3/32-inch (0.093-inch) wire, and uses an M8 x 1.25-6g thread size. It is sold in packs of 25 and is installed by professional welders and MIG gun technicians in heavy industrial environments.

This contact tip is designed for use with Tweco Spray Master and Tweco No. 6 MIG guns rated at 350 to 600 amps, as well as compatible Tweco MIG gun series. Its thick-walled construction acts as a heat sink, drawing heat away from the arc source during sustained high-amperage spray transfer and heavy fabrication work. The twist-lock design seats the tip securely against the gas diffuser, increasing electrical contact surface area and improving conductivity. Each tip is marked with the part number and wire diameter for fast identification during changeouts in production welding settings.

Key Features

• Accepts 3/32-inch (0.093-inch) wire with a 0.106-inch nominal bore and plus or minus 0.003-inch ID tolerance
• Rated for heavy-duty welding applications up to 600 amps
• Machined from 122 DHP copper alloy for consistent bore surface and excellent electrical conductivity
• Twist-lock design locks tip against gas diffuser without loose threads; quarter-turn clockwise reveals a new wear point to double tip service life
• Thick-walled design functions as a heat sink to conduct heat away from the arc
• Part number and wire diameter marked on each tip for quick field identification
• Compatible with both slip-on and thread-on nozzle styles

Compatibility

Compatible with Tweco Spray Master and Tweco No. 6 MIG guns rated 350 to 600 amps, as well as specific Tweco MIG gun series requiring an M8 x 1.25-6g threaded contact tip with a 0.375-inch OD.

Installation Notes

Contact tip replacement is performed by qualified welding technicians or MIG gun operators. Always power down the welder and allow the gun to cool before servicing consumables. Thread the tip fully onto the gas diffuser by hand, then use the twist-lock feature to seat it securely. Inspect the bore diameter and tip condition at regular intervals; rotate a quarter-turn clockwise to expose a fresh wear point before replacing the tip entirely.
