Bought this mixer for a special job where we had a big project when we had 10 working benches. Saves a ton on gas by having one source.

We had a special application with multiple welders and this mixer helped us save on the gas bill. It took some work to set up but it worked out great for our setup. Customer service superseded my expectations.
