That's similar in size to a Miller or Lincoln mid-size engine-drive
arc welder. For that size engine (16-20 hp) compare the pricing to a
Miller Bobcat or Lincoln Ranger and you have an arc welder along with
power generation.

I have heard that arc welders put out really dirty power because they
use brushes instead of the brushless rotating field design that home
generators use.

Brush generators usually put out much better power than brushless units do -
at least the low cost quadniture excited brushless units. Some of the
welder generators put out dirty power becuase they are inverter units that
use cheap square wave (AKA modified sine wave) inverters.
