Tweco 1160-1428 Mig Contact Tip 0.062 in Wire

Product Description

The TWECO 1160-1428 is a threaded MIG contact tip designed for 0.062 inch (1/16 inch) wire diameter and used in heavy-duty MIG welding applications up to 600 amps. Manufactured from 122 DHP copper alloy tubing, it delivers excellent electrical conductivity and a consistent inside diameter surface. The 1.5 inch tip features an M8 x 1.25-6g thread and a nominal bore of 0.073 inches with a tolerance of +/- 0.003 inches. HVAC, industrial, and general welding technicians install this tip as a consumable component of MIG gun assemblies where reliable arc transfer and long service life are required.

This contact tip is suited for heavy-duty MIG welding in residential, commercial, and industrial settings. It is designed for high-amperage applications reaching up to 600 amps, making it appropriate for structural, fabrication, and maintenance welding tasks. Each tip is marked with the part number and wire diameter for fast identification during changeovers, reducing downtime in production environments. The threaded style ensures secure, consistent contact with the gas diffuser when installed in a compatible MIG gun.

Key Features

• Rated for heavy-duty welding applications up to 600 amps
• Machined from 122 DHP copper alloy for excellent electrical conductivity and consistent bore surface
• Inside diameter tolerance held to +/- 0.003 inches for reliable wire feed
• M8 x 1.25-6g threaded style ensures proper seating against the gas diffuser
• Part number and wire diameter marked directly on tip for easy field identification
• 0.375 inch OD with 1.5 inch length for standard MIG gun fitment

Compatibility

Designed as an OEM-style replacement contact tip for MIG guns compatible with M8 x 1.25-6g threaded tips accepting 0.062 inch wire diameter.

Installation Notes

Contact tips are installed and serviced by welders and welding technicians as routine consumable replacements. Always power down the welding machine and allow the gun to cool before removing a spent tip. Use the appropriate tip wrench to avoid cross-threading the M8 thread; overtightening can deform the bore and affect wire feed quality. Follow the gun manufacturer guidelines and applicable AWS safety standards when servicing MIG gun consumables.
