Tweco 1250-1441 Welding Nozzle 3/4 Inch Bore 25 Series

Product Description

The TWECO 1250-1441 is a 25 Series MIG welding nozzle designed for medium and heavy duty welding applications rated up to 550 amps. It uses a 3-piece construction consisting of a nozzle housing cut and formed from 122 DHP copper alloy tubing, a nozzle insert machined from solid brass with internally threaded fitment to the conductor tube, and a G7 silicone nozzle insulator for electrical insulation. The tapered nozzle profile eliminates the need for an additional separate insulator. The part number is roll stamped on the outside surface for quick identification in the field. Weight is 0.19 pounds.

This nozzle is suited for use on TWECO 25 Series MIG gun assemblies in professional welding environments. Typical applications include fabrication shops, structural welding, and heavy manufacturing where sustained high-amperage output is required. The 3/4 inch bore diameter supports shielding gas flow appropriate for medium to heavy duty weld puddles. This nozzle is sold individually and is a direct component of the Weldskill 25 Series nozzle system.

Key Features

• 3-piece nozzle design: 122 DHP copper alloy housing, solid brass insert, G7 silicone insulator
• Rated for welding applications up to 550 amps
• Tapered nozzle design does not require an additional insulator
• Internal threads machined to match the conductor tube for secure fitment

Installation Notes

Installation is performed by a qualified welding technician or MIG gun service professional. Power down and disconnect the welding machine before removing or installing nozzle components. Thread the nozzle insert onto the conductor tube by hand until snug, taking care not to cross-thread the machined brass insert. Inspect the G7 silicone insulator for damage before returning the gun to service.
