Tweco 1220-1204 Velocity Adjustable Mig Welding Nozzle

Product Description

The TWECO 1220-1204 is an adjustable Velocity series MIG welding nozzle cut and formed from 122 DHP copper alloy tubing. It slides over the standard nozzle insulator and allows the technician to set the exact contact tip-to-nozzle relationship required for the application. The part number is roll-stamped on the outside surface for fast identification in the shop or field. Weighing 0.14 pounds and measuring 1.83 inches in length with a 0.93-inch diameter, this nozzle is built for professional MIG welding setups where tip positioning precision directly affects arc quality and weld consistency.

This nozzle suits a range of MIG welding applications in fabrication, structural, and pipe welding environments. Its adjustable design supports three primary tip configurations: recessed for higher heat and longer electrical stick-out or nozzle-to-workpiece contact situations such as tack, spot, and stitch welding; flush for shorter stick-out and tighter arc lengths; and protruding for open root pipe or tight joint access. Licensed welding professionals and certified fabricators working in both shop and field conditions will find this nozzle appropriate for daily production use.

Key Features

• Adjustable nozzle allows precise contact tip-to-nozzle positioning for recessed, flush, or protruding tip configurations
• Formed from 122 DHP copper alloy tubing for reliable thermal and electrical conductivity
• Part number roll-stamped on the exterior surface for quick identification
• Slides over the standard nozzle insulator — no special adapter required
• Recessed setting suited for high-heat applications, tack, spot, and stitch welding
• Protruding setting suited for open root pipe and tight joint access

Compatibility

Designed as an OEM-style replacement nozzle for TWECO Velocity series MIG welding guns that accept the standard nozzle insulator configuration.

Installation Notes

Installation should be performed by a qualified welding technician with the welder powered down and the wire feeder disabled before handling front-end consumables. Slide the nozzle over the insulator and adjust the tip-to-nozzle position before energizing the gun. When using a protruding tip configuration, take care to avoid contact between the tip and the workpiece, as arcing can damage front-end components. Follow the equipment manufacturer guidelines and applicable AWS or facility safety standards for consumable replacement.
