Miller MDX-250 MIG Gun 250A 10 ft

The Miller MDX-250 is an air-cooled MIG welding gun rated at 250 amps with a ten-foot cable. It accepts solid and flux-cored wire up to .035 inch diameter and connects to Miller-compatible rear fittings. A fixed neck angled at fifty degrees and a straight handle with standard trigger complete the assembly. The gun carries the manufacturer part number 1770035.

Suited for light fabrication

Welders running short-to-medium runs at 250 amps on carbon dioxide or mixed shielding gas will find the duty cycle rated at sixty percent and one hundred percent appropriate. The fixed neck and straight handle limit positional flexibility, so operators who need rotatable necks or pistol grips for tight access should consider other configurations.

AccuLock MDX tip series simplifies consumable

The gun uses the AccuLock MDX contact-tip series, which allows tip replacement without removing the nozzle or diffuser. This reduces downtime during tip changes and helps maintain consistent electrical contact. No additional software or accessories are bundled with the gun.

Questions about this item

Does this 1770035 gun require a Miller-compatible rear connection on my welder to operate?

Yes, the gun is built for a Miller-compatible rear connection so the power cable and gas fitting must match that pattern on your machine.

Will the fixed 50-degree neck tube and 10 ft cable reach the same work positions as my old flexible-neck gun?

The neck angle is fixed at 50 degrees and the cable is 10 ft long, so you can only reach positions that suit that bend radius and length.

How do I verify the gun is running at its rated 60 percent duty cycle with CO2 or mixed gas?

Weld continuously at 250 A for six minutes out of every ten without the gun overheating; the duty-cycle rating is based on CO2 or mixed gas.
