About Us

Corporate Building

Taking innovatively sound steps since 1929, Miller Electric Mfg. Co. has grown from a one-man operation selling products in Northeast Wisconsin, to what is today the world’s largest manufacturer of arc welding and cutting equipment. Without skipping a beat, Miller keeps the tradition alive by delivering ruggedly reliable equipment of the highest quality. Our history is rich in making you, the customer, our top priority.

Recognizing the need for a better solution to power equipment on a mechanic’s truck, Miller Electric Mfg. Co. introduced EnPak™ Mechanic Series. Miller—the most trusted brand in welders and generators—engineered, designed and built EnPak for maximum jobsite performance.

EnPak Mechanic Series is the world’s only diesel engine-driven air compressor, generator and hydraulic pump for mechanic’s trucks. EnPak provides mechanics with all the power needed to run air tools, hydraulic cranes and electrical equipment—all with the truck turned off. EnPak will revolutionize the way that you work—turn off your truck and turn on your EnPak—you’ll be glad you did.
