Tweco 1260-1260 Mig Welding Nozzle HD26 600 Amp

Product Description

The TWECO 1260-1260 is a heavy duty, air-cooled MIG welding nozzle from the HD26 Series, rated for welding applications up to 600 amperes. Built around a 3-piece construction, the nozzle combines a red brass alloy 230 housing, a solid brass machined insert, and a G7 silicone insulator. The insert is crimped in place to slide over the metal spring of the gas diffuser, eliminating the need for a separate insulator. The part number is roll-stamped on the exterior surface for fast identification in the field. Weighing 0.42 pounds, it is sold individually and suits demanding production and fabrication environments.

This nozzle is designed for heavy duty MIG welding operations requiring sustained high-amperage output. Its air-cooled design and 600-amp rating make it appropriate for structural fabrication, heavy equipment repair, and industrial manufacturing settings where duty cycles and heat loads are elevated. Licensed welders and certified welding technicians are the primary installers. The 3-piece assembly is compatible with TWECO HD26 Series torch configurations that use the standard gas diffuser spring-mount system.

Key Features

• Rated for welding applications up to 600 amps
• 3-piece design: brass alloy 230 housing, machined solid brass insert, G7 silicone insulator
• Crimped insert slides over gas diffuser metal spring — no additional insulator required
• G7 silicone insulator provides electrical isolation from the gas diffuser
• Part number roll-stamped on exterior surface for fast field identification
• Air-cooled construction suited to heavy duty production environments

Compatibility

Designed for use with TWECO HD26 Series MIG welding torches rated up to 600 amperes using the standard gas diffuser spring-mount system.

Installation Notes

Installation is performed by certified welders or qualified welding technicians. Disconnect and de-energize the welding machine and allow the torch to cool fully before removing or installing nozzle components. Confirm the gas diffuser spring is properly seated before sliding the nozzle insert into place. Follow the torch manufacturer's assembly sequence and applicable AWS safety standards during service.
