Miller AccuLock MDX 250 EZ-Select MIG Gun with S Lock (1770046)
The Miller MDX 250 EZ-Select MIG gun allows the user to select from up to four weld programs by tapping the gun trigger. The new ergonomic handle features and overmolding for improved grip and a rear swivel strain relief. The gun’s AccuLock consumables with dual-locked, front-loading liner ensures smooth, consistent wire feeding for reliable operation. This particular MIG gun utilizes Bernard's Acculock S consumables, not Miller MDX Lock consumables. Miller MDX consumables may be used, however you would need to swap out the diffuser, contact tip, and nozzle.
