Excel Power - MillerWelds

Trailblazer® welder/generators

Excel™ power

Power at idle — a Miller exclusive


Unlike competitive machines that provide auxiliary power only at 3,600 rpm (max), Excel power delivers a full 2,400 watts (20 A) of 120 V inverter-based, pure sine wave power at idle. With Excel power, you can operate jobsite tools like grinders and lights at quiet, fuel-saving engine speeds.  

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

Longer runtimes. More profitability.


Based on typical usage — 150 amps welding 40% of the time, 20 amps of generator power 30% of the time, and idling without load 30% of the time. 

Longer runtimes mean more productivity — and less refueling time and expense. You want the most productive and profitable jobsite. Which is why you need a Trailblazer welder/generator.


Only Trailblazer welder/generators break the 20-hour runtime barrier, using Electronic Fuel Injection (EFI) and the Miller-exclusive combination of Auto-Speed technology and Excel power to give you the longest runtimes in the category — for the most productivity and profitability.

More fuel-efficient generator operation.

Based on generator-only use for total runtime.

You depend on a welder/generator to reliably power multiple jobsite tools — and that jobsite’s profitability is directly impacted by that welder/generator’s fuel efficiency. Which is why you need a Trailblazer welder/generator with EFI and Excel power.

When tested against a competitive EFI-equipped welder/generator, the Trailblazer 325 EFI with Excel power is 52 percent more fuel efficient in generator-only use, with its engine operating at 2,400 rpm — compared to the competing machine’s engine operating at 3,600 rpm at ANY load. Excel power and Auto-Speed technology, which matches engine speed to load, not only deliver greater fuel efficiency, but less noise. Excel power: available only from Miller.
