Actually more "power" from the engine would be a good thing.
The 7kw generator is rated to put out 29 amps at 240 volts. Problem is the plasma cutter uses 30 to 31 amps. The electrical portion can take that kind of power out put, but the engine rpms drop off, cant keep up.
I need to check apparent power on my plasma.
Yeah I can run it fine by turning it down a little, but who wants to do that.

Running a smaller engine harder does save gas.
My air compressor uses a real old 5 horsepower flat head briggs, if I bump compression it would make more power, with more power I could stick a larger pully on the engine and get more air out of the compressor. Maybe run 1 compressor instead of 2.

The 7kw generator has a new style Briggs and Stratton with an OHV engine. Bumping compresion isnt as easy.
The 1900w generator has a slightly newer version of the engine on my air compressors engine, the generator is rated for 18 or 19 amps but will hold a 22amp load no problem. So its good.

I am running into a basic fundamental problem where the rate of work I can do is limited by the horsepower output of my machines.
