Tweco 1210-1100 Mig Nozzle 180A 3/8 Inch Bore Air Cooled

Product Description

The TWECO 1210-1100 is a slip-on MIG welding nozzle from the Weldskill 21 Series, rated for light to medium duty applications up to 180 amperes. This is a 3-piece nozzle assembly: the housing is cut and formed from 122 DHP copper alloy tubing, the insert is machined from solid brass with internal threads matched to the gas diffuser, and the insulator is molded from G7 silicone material. The 3/8 inch bore and tapered nozzle geometry are suited for standard GMAW torch setups. The part number is rolled-stamped on the exterior for quick identification in the field. Licensed welding professionals and fabrication shops install this nozzle as a consumable replacement on compatible 21 Series torches.

The TWECO 1210-1100 is designed for light to medium duty GMAW applications in both shop and field environments. The self-insulated, tapered 3-piece construction eliminates the need for a separate external insulator, simplifying consumable inventory. The nozzle threads directly onto the gas diffuser, making changeovers fast during production or repair welding. Tip recess range is 1/8 inch to 5/32 inch. This nozzle suits fabricators and welding technicians working with wire-feed processes where consistent shielding gas coverage at the weld pool is required.

Key Features

• Rated up to 180 amperes for light to medium duty GMAW service
• 3/8 inch bore diameter with tapered nozzle profile
• Housing formed from 122 DHP copper alloy tubing for thermal conductivity and durability
• Brass insert with machined internal threads for precise gas diffuser fit
• G7 silicone insulator provides electrical isolation without a separate insulator component
• Part number rolled-stamped on outer surface for easy field identification

Compatibility

Designed as a slip-on replacement nozzle for TWECO Weldskill 21 Series air-cooled MIG torches. Thread-on variants are also available within the 21 Series line.

Installation Notes

Installation is performed by qualified welding technicians as part of routine consumable maintenance on GMAW torches. Disconnect the welder from power and allow the torch to cool before removing a worn nozzle. Thread the nozzle clockwise onto the gas diffuser until fully seated — do not overtighten, as this can damage the brass insert threads. Inspect the gas diffuser and contact tip for wear or spatter buildup before installing the new nozzle.
