Auto-Speed Technology - MillerWelds

Trailblazer® welder/generators

Auto-Speed™ technology

Matches engine speed to load — a Miller exclusive


Get the welding power you need — plus reduced fuel consumption and lower noise levels for a more-profitable, safer jobsite. 

Unlike competitive machines that operate at 3,600 rpm (max) under any load, Miller-exclusive Auto-Speed technology responds to weld requirements by automatically adjusting engine speed to one of four rpm levels so the engine never works harder than necessary. 

Refueling time and operating costs are reduced, which means more productivity and profitability. Plus everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered. Auto-Speed technology: available only from Miller.
