169599 - Miller MIGmatic M-25 Replacement MIG Gun 15ft 250A

Miller M-25 MIG Gun (169599) - Professional Grade Welding Torch

The Miller M-25 MIG Gun (Stock No. 169599) is a premium 250-amp air-cooled torch designed to deliver consistent performance and exceptional durability in industrial environments. Engineered as part of the renowned MIGmatic™ series, this gun is the standard replacement for a wide range of Millermatic® power sources, including the Millermatic 200, 210, 212, 250, 251, 252, and Vintage models. It is also fully compatible with all current Miller wire feeders, making it a versatile choice for fabrication shops and maintenance departments.

Constructed with a single-piece, high-impact handle, the M-25 is built to withstand the rigors of daily shop use. The handle design is ergonomic yet rugged, often described as nearly indestructible, ensuring a long service life even in harsh conditions. A key feature of this model is the 360-degree rotatable gooseneck. This design allows welders to adjust the angle of the torch neck to access hard-to-reach joints without straining their wrists or compromising the wire feed path. The trigger mechanism is designed for reliability, capable of enduring thousands of cycles without failure.

The cable assembly is 15 feet (4.6 meters) long, providing ample reach for working around large assemblies or vehicles. To ensure smooth wire delivery, the gun features a steel spring strain relief at the connection point. This reinforcement protects the power cable from abrasion and prevents the liner from kinking at sharp angles, which is critical for maintaining a stable arc and preventing wire bird-nesting. The gun comes ready to feed wire diameters ranging from .030 to .045 inches (0.8-1.2 mm), covering the most common MIG welding applications.

Maintenance is simplified with the M-25's three-piece nozzle construction. This design helps prevent the nozzle from rocking on the contact tip adapter and reduces wear, extending the life of your consumables. Whether you are welding mild steel, stainless, or aluminum (with the appropriate liner), the Miller M-25 delivers the reliability professionals expect from the Miller brand.
