I have a 12 year old cold water pressure washer that was rated about 2 gal a minute at 3,000 psi. I bought from sears.

I'm at the stage where we are welding on more construction equipment, Gravel trains and trailers.

We also do a fair amount of structural fabricating where we have to paint our steel that has oil on it from the mill.

I never thought that electric would be strong enouph until I tried a electric unit a local farmer friend bought and wow was I impressed.
Its electric 4 gallons per minute at 3000 psi with hot water.
They also make a sand blaster that hooks up to it with the water.

The gas unit they sell is a 13 HP with 3.5 gallons at 3500psi with hot water

I really like the idea of not starting an engine every time I want to clean something and the unit can sit just inside the door verses having to drag the gas powered one outside everytime I use it.

Will the additional 500 psi be worth the hastle.
