Miller builds the most durable and reliable industrial engine driven welders available.

When you’re in the middle of nowhere, there’s not always a repair shop next door, meaning you can lose thousands on a job if your engine driven welding machines let you down. So when conditions get tough and other brands bite the dust, look to Miller engine driven welders to keep performing. Miller engine driven welders are designed to run 24 hours a day, seven days a week if required, so you can’t overwork them.

The Air Pak™ engine driven welder is a complete mobile welding, air and power workshop for on-site maintenance and fabrication. With independent generator power, the Air Pak engine driven welder delivers 4000 watts of continuous output for lighting and power tools, even while welding at 500 Amps.

The Miller engine driven welder range includes: Big Blue Air Pak, Big Blue 600X, Big Blue 400X, Trailblazer 302/325 and the Bobcat 250.

Regardless of the application, Miller has an engine driven welding machine to suit any application.
