Tweco 1220-1310 Mig Welding Nozzle Flush 3/8 Inch Bore

Product Description

The TWECO 1220-1310 is a heavy-duty, flush-style MIG welding nozzle designed for air-cooled MIG guns. Cut and formed from 122 DHP copper alloy tubing, it provides a solid copper conductor path with minimal connections, optimizing electrical surface contact and reducing heat buildup. The 3/8-inch bore accommodates standard wire sizes and the flush tip geometry is suited for shorter electrical stick-out applications. Licensed welders and fabricators install this nozzle as a front-end consumable on compatible TWECO-style MIG torches. The design eliminates the need for a separate diffuser, reducing the number of parts to stock on the job.

This nozzle is intended for air-cooled MIG welding applications across light industrial and heavy fabrication environments. Flush-style nozzles are well suited for shorter arc lengths where the tip sits closer to the work piece. The nozzle is adjustable, allowing the technician to set the precise contact tip-to-nozzle relationship required by the weld procedure. The part number is roll-stamped on the exterior surface for fast identification in the shop or field. The nozzle slides over a standard nozzle insulator without specialty tooling.

Key Features

• 3/8-inch bore flush nozzle for shorter electrical stick-out and tighter arc lengths
• Nozzle housing cut and formed from 122 DHP copper alloy for high conductivity and heat resistance
• Solid copper conductor path with fewer connections to optimize electrical surface contact
• Adjustable nozzle allows precise setting of contact tip and nozzle relationship
• No separate diffuser required, reducing parts inventory
• Part number roll-stamped on outer surface for easy identification

Compatibility

Designed as an OEM-style replacement flush nozzle for TWECO HD22 series air-cooled MIG torches using a standard nozzle insulator.

Installation Notes

Installation is performed by qualified welders or MIG torch technicians. Power down and de-energize the welding machine before servicing front-end consumables. The nozzle slides onto the standard nozzle insulator by hand and is adjustable without additional tooling. Inspect the nozzle insulator and contact tip for wear each time the nozzle is replaced to avoid premature consumable failure.
