A while back I was visiting Big Cat Habitat with a friend who is involved with them. My friend said there was some sort of welding machine that nobody knew how to use and might I check it out. Turned out to be a $5k Miller Mig welder! Well, I went out and worked with some wonderful guys (including Jurgen the tiger trainer) and taught them how to use the mig.
They had been using stick welders to build enclosures, that need lots of clean up and makes lots of nasty fumes. Knowing how to use the mig means they can do way more faster and cleaner. Very happy to be of service!
