196827 - Miller M-25 MIG Gun Replacement Gooseneck Tube Assembly 60 Degree

Restore Precision to Your Miller M-25 MIG Gun

The Miller 196827 Gun Tube Assembly is a critical component for maintaining the performance of your Miller M-25 MIG welding gun. Often referred to as the "gooseneck" or "conductor tube," this part is responsible for transferring the welding current to the contact tip and directing the shielding gas over the weld pool. Designed with a fixed 60-degree angle, it provides the ergonomic versatility needed for a wide range of industrial applications, from automotive repair to heavy structural fabrication. This assembly is rated for the full 250-amp output of the M-25 gun, making it a robust solution for professional welders.

Technical Specifications and Performance

Manufactured to Miller's exacting standards, the 196827 tube assembly ensures optimal electrical conductivity and thermal management. The core is crafted from high-conductivity alloys that minimize resistance and heat buildup, which is essential for maintaining a stable arc during long duty cycles. The exterior is wrapped in durable, heat-resistant insulation that withstands the harsh environment of the welding shop, protecting the neck from spatter adhesion and electrical shorts. A damaged neck is a common cause of "stuttering" wire feed; replacing a bent or worn tube can often solve feeding problems that changing the liner alone cannot fix.

Seamless Integration

This replacement part is engineered for a perfect fit with the Miller M-25 gun, which is standard equipment on legendary machines like the Millermatic 250, Millermatic 252, and Millermatic 250MP. It accepts standard Miller consumables, ensuring you don't need to change your stock of tips, nozzles, or diffusers. The precise machining of the threads ensures a tight gas seal, preventing atmospheric contamination of the weld zone. When your gun neck becomes loose, stripped, or clogged beyond cleaning, the 196827 is the direct replacement you need.

Maintenance and Longevity

To maximize the life of your new gun tube, we recommend regular inspection of the O-rings and mating surfaces during consumable changes. Keeping the interior of the tube clean and free of metal shavings will ensure consistent gas flow. This assembly is sold as a single unit, ready to install. It does not include the gas diffuser or nozzle, so be sure to transfer your existing usable consumables or purchase new ones to complete the refurbishment of your MIG gun.
