That is pretty impressive for that size of generator. Would you mind
sharing what brand and model it is.

Wacker GS 8.5
It has a B&S 16 HP vanguard

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.
