A ton. Which is just fine by me. Been playing around with it and like it a lot. Getting comfortable with it. Lots of challenges ahead with this project for me using it too. Vertical welds. Upside down welding! Plus since I plan to install tubs out back I'll be doing some thin metal stuff too. Also should be some stainless and aluminum work along the way. Plus a mini-project at some point I believe will happen. I can see me wanting/needing a rotary welding fixture. Sure would make some of the exhaust fab work easier (and much better looking!).You’ll finally get to use the TIG.
