Tweco 1160-1182 Mig Contact Tip 0.045 in 0.051 Bore 25 Pack

Product Description

The TWECO 1160-1182 is a robotic MIG contact tip designed for heavy-duty welding applications up to 600 amps. It accommodates 0.045-inch wire with a 0.051-inch nominal inside diameter bore and measures 1.5 inches in length. Machined from chrome zirconium 1815 alloy copper tubing, the tip delivers a consistent, smooth inside diameter surface held to a tolerance of plus or minus 0.003 inches. The M8 x 1.25-6g threaded style ensures reliable contact with a gas diffuser when installed on a MIG gun. Licensed welding technicians and robotic welding cell operators install this tip as part of routine gun maintenance. Each tip is marked with part number and wire diameter for quick identification. Sold in packs of 25.

This contact tip is intended for high-amperage MIG welding environments, including robotic and automated welding cells as well as heavy industrial manual MIG applications. At 600 amp capacity, it is suited for demanding production welding where tip wear and electrical consistency are critical. The chrome zirconium alloy construction is harder than standard copper alloy tips, increasing wear resistance and extending service intervals between tip changes. Welding professionals working in fabrication shops, structural steel, and heavy equipment manufacturing will find this tip appropriate for their applications.

Key Features

• Chrome zirconium 1815 alloy construction provides greater hardness and wear resistance than standard copper alloy contact tips
• Inside diameter held to plus or minus 0.003-inch tolerance for consistent wire feeding and electrical contact
• M8 x 1.25-6g threaded style ensures secure seating against gas diffuser
• 0.051-inch nominal bore accommodates 0.045-inch MIG wire
• Each tip marked with part number and wire diameter for fast field identification
• Rated for welding applications up to 600 amps
• Sold in a 25-piece pack for production and robotic welding environments

Compatibility

Designed for use with MIG gun assemblies requiring an M8 x 1.25-6g threaded contact tip accommodating 0.045-inch wire, including robotic and standard MIG welding guns rated for heavy-duty operation up to 600 amps.

Installation Notes

Contact tip replacement is performed by welding technicians during scheduled gun maintenance or when tip wear causes arc instability or wire feeding issues. Shut down and de-energize the welding power source and allow the gun to cool before handling consumables. Thread the tip into the gas diffuser by hand first, then snug with an appropriate wrench to avoid cross-threading the M8 threads. Do not overtighten, as this can damage the diffuser threads or distort the tip bore.
