Tweco 1210-1110 Mig Nozzle 1/2 Inch Bore 180A

Product Description

The TWECO 1210-1110 is a self-insulated copper MIG welding nozzle designed for use with Tweco mini-MIG-gun MIG guns rated up to 180 amps. Built from 122 DHP copper alloy tubing, this nozzle features a 1/2-inch bore and an overall length of 2.224 inches with a 3/4-inch outer diameter. Its three-piece construction integrates the nozzle housing, a solid brass nozzle insert with machined internal threads, and a G7 silicone nozzle insulator that provides the electrical isolation required from the gas diffuser. The part number is rolled-stamped on the outer surface for fast field identification. Sold in a pack of 2, this nozzle is installed by MIG welders and weld shop technicians in light to medium duty applications.

This nozzle threads directly onto a standard gas diffuser and is suited for light to medium duty MIG welding at up to 180 amps. The recessed contact tip relationship of 0.125 to 0.156 inches makes it appropriate for higher-heat applications, tack welding, spot welding, and stitch welding where longer electrical stick-out is needed or where the nozzle may contact the workpiece. The M11-1.5-6H thread size matches the gas diffuser precisely, ensuring a secure fit. The three-piece design eliminates the need for a separate insulator, reducing part count during maintenance.

Key Features

• 122 DHP copper alloy housing cut and formed from tubing for reliable heat dissipation
• Solid brass nozzle insert with machined internal threads to match the gas diffuser
• G7 silicone nozzle insulator provides electrical insulation without a separate insulator component
• Recessed tip design suited for higher-heat, tack, spot, and stitch welding applications
• Part number rolled-stamped on outer surface for quick identification in the field
• M11-1.5-6H thread size for secure, repeatable attachment to the gas diffuser

Compatibility

Designed for use with Tweco mini-MIG-gun MIG guns on standard gas diffusers rated up to 180 amps.

Installation Notes

Installation is performed by a qualified MIG welder or welding technician. Always power down the welding machine and allow front-end components to cool before removing or installing nozzles. Thread the nozzle onto the gas diffuser by hand until snug — do not overtighten, as this can damage the brass insert or the diffuser threads. Inspect the silicone insulator for cracking or burn-through during routine maintenance and replace the nozzle as a unit if insulation integrity is compromised.
