The best welding gun is the one you never have to think about because it’s comfortable, it’s durable and it gets the job done. MDX Series MIG guns have been designed to be exactly that. The new ergonomic handle features over molding for improved grip and a rear swivel strain relief for reduced welder fatigue. The gun’s AccuLock™ consumables with dual-locked, front-loading liner ensures smooth, consistent wire feeding for reliable operation.
