Tweco 1150-1210 Mig Contact Tip 0.093 in 500A 25 Pack

Product Description

The TWECO 1150-1210 is a 15 Series Heavy Duty MIG contact tip designed for high-amperage wire feed welding applications. It accommodates 3/32 inch (0.093 inch) wire with a 0.106 inch nominal bore ID and measures 1.97 inches in length. 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. Rated for use up to 500 amps, it is installed by licensed welders and maintenance technicians in demanding industrial and fabrication environments. Sold as a pack of 25.

This contact tip is suited for heavy duty MIG welding operations in both industrial and fabrication settings. It is compatible with 200 to 500 amp Tweco No. 5 MIG guns and specific Tweco MIG gun series. The threaded style with 5/16 inch-18 UNC-2A thread size ensures secure, consistent contact with a gas diffuser. The tip accepts slip-on or thread-on nozzle styles and is designed for high-cycle production welding where tip longevity and consistent arc performance are critical.

Key Features

• 122 DHP copper alloy construction provides excellent electrical conductivity and heat dissipation
• Bore ID tolerance held to plus or minus 0.003 inches for consistent wire feed
• Thick-walled design acts as a heat sink, conducting heat away from the arc source
• Twist-lock mechanism locks tip in place when installed; quarter-turn clockwise reveals a new wear point, doubling tip life
• Each tip is stamped with part number and wire diameter for easy field identification
• 5/16 inch-18 UNC-2A thread for secure gas diffuser contact

Compatibility

Compatible with 200 to 500 amp Tweco No. 5 MIG guns and specific Tweco MIG gun series requiring a 15 Series Heavy Duty contact tip with 5/16 inch-18 UNC-2A thread and 0.093 inch wire diameter.

Installation Notes

Contact tips are installed and replaced by qualified welders or MIG gun service technicians. Always power down the welding machine and allow the gun to cool before replacing the contact tip. Use the appropriate tip wrench to avoid over-tightening, which can damage the gas diffuser threads. Ensure the replacement tip thread size and bore diameter match the gun specifications before installation.
