You can add an extra muffler to the welder and it will quiet down quite a bit
It will still be pretty damn loud, welders like Ed's run at 3600 RPM. The quiet gens are 1750 RPM. At the higher RPM there is just a lot of valve noise and even noise coming through the intake.
What do you want to power Ed?
