Fantastic generator works great in the field with welders,drills,saws and portable air comp.Hard to move around on ruff ground have to use tractor with boom but no problem because it works everything.Great instruction book.I have only used on propane because have to install transfer switch to bring house up to national electric code and surge protectors.

A beast of a generator!
I first bought a 9500df for a welding trailer rig that I was setting up. However, I discovered that the 9500df puts out 23%THD and the welder would go in safe mode when on high settings. I contacted Westinghouse and found out that I needed the 12000df model that puts out <5% THD and costed twice as much. But it works awesome with my multi processor welder. Also, it has a "low idle" switch that isn't in the manual or shows up in the web site photos. This is a cool feature that is more for job site application so your generator idles down when it's not pulling any power.

I will review it Once I use it. Well built. Heavy.
by Fred97
Great Features
Bought this generator after experiencing TX Winter Storm without power and heat for 30+ hours. Have an electrician installed the line in and interlock switch on my panel and test drive the generator with success. Start on the 1st crank. Now we are ready if we have to go without power in the future.

It's a Beast
Here is the Wgen 9500 next to my Wgen 12000. Started right up. I bought the 9500 from Amazon and it was not on a pallet and was beat up where the shipper rammed a forklift through the box. The 12000 bought from Lowes was on a pallet and in pristine condition. No more dark nights for me.

Generator meets advertised quality and performance
Perfect for my needs. I love it, next time I'll buy one for my daughter.
by Mike Z
Great Features
Product requires some minor assembly but very simple. Have not operated the unit yet but I like the layout of the control panel. The battery charging port is a really nice feature. The terminals on the battery need to be located on top simplify battery connections. Also a place to store the spark plug tool and oil funnel would be nice. Changing the oil looks to be a messy encounter. Maybe extending the drain beyond the frame or enlarge the hole near the drain plug.
by nortonld
Large and powerful
Set up was very easy, nothing was damaged and all parts were included. You have to fill oil, which was provided. the first time starting was with gas and it started with no issues. I used propane and the engine sounded a little strange, there may be some setting that need to be adjusted or the regulator may need to be broken in. The unit is large but is easy to move with 5 gal of gas in the tank. I gave it 4 stars because of the sound it made with propane.
My wife and I decided to invest in a generator after the most recent storm and sustained power outage. We’ve grown tired of emptying fridges and freezers and other inconveniences that go along with extended power outages. We haven’t had the chance to use it in that situation yet, but after extensive research and discussions with some electrician friends, I’m hope for the best with this. We decided to go bigger on the size to eliminate taxing the generator and the electric motors/pumps of the various things we intend to run. It’s a nice generator with real nice features. The build quality looks and feels solid and despite it’s weight, its easy to maneuver around and believe me when I say that I’m not in the best of shape. I am hopeful my family will get years of service from this thing.
