This is a brand new 12 ft MASTERWELD replacement M25 welding mig gun. This Best MIG gun is a direct replacement for a Miller MIGmatic™ M-25 welding gun, Part #169596. The front end parts of this gun are completely interchangeable with the Miller gun - that's right, it uses the same 169726 gas nozzle, the same 169728 tip adapter, the same 169729 nozzle adapter, and the same contact tips as the OEM Miller gun. This 12 ft long gun will handle .030” and .035” diameter welding wires. It will feed all types of wire, steel wire using gas, flux cored wire requiring no gas, stainless steel wire, and with a teflon liner, you can feed aluminum wire. It comes standard with a .035” diameter tip in the welding gun. If you need extra tips, nozzles and tip adapters, now is a great time to stock up, as they ship for no additional shipping charge.
