What you are saying about reducing the load on a generator may be correct ?
But , I would like to point out to you , the reactive amperage is not read by the traditinal power company mechanical watt meter . Which is one reason PF is kind of a touchy subject with the power company . Not so much for residental , but for commercial or industrial companies .
I do not know if electronic watt meters can read reactive amps ?
I worked at an iron foundry , years ago . Two electrical induction furnaces . ( Big inductive reactance ! )
They each had a capacitor bank . The controls would switch in / switch out more or less capacitors . It would maintain a PF of from .95 to 1.05 .
Lastly , as long as you are hooked up to commercial power , it is probably a non issue , as long as you are not doing much welding . If you are doing a lot of welding , maybe so ?
God bless
