What Makes Miller Industrial Engine Drives So ?

Every component in a Miller industrial engine drive is engineered and built to assure ultimate reliability in the most punishing conditions. And they are rigorously tested to the toughest real-world conditions to keep working in a tough world.

No matter how well it’s built, any machine can fail if its critical circuit boards are compromised. Miller makes two types of industrial engine drives, both of which ensure that no critical circuit boards are left vulnerable.

“CC” Stick and TIG Models — Miller’s robust, efficient constant current (CC) industrial engine drives for Stick and TIG welding are designed with no circuit boards that are critical to the machine’s operation. That means no boards can shut down the machine if they fail.

“CC/CV” Multiprocess Models — Miller’s Multiprocess PRO 300 and Big Blue® models of industrial engine drives include circuit boards for superior arc control and welding versatility. These boards are protected by the Vault, a hermetically-sealed aluminum case that is impenetrable to dust, salt, and moisture.

“Other machines would cut out when we gouged too long with them. With the Miller, I gouged hard all day in 98 degree heat and never had a shutdown when we were running 3/8-in carbons.” When welding, “The Big Blue starts out hot, where I want it, and stays steady on its heat all day.”

— Welder Tommy Langley, Fluor Daniel/Chevron Oil Refinery
