Aside from my Webers, I would have to say my newest focus in welding. It started with a Lincoln arc welder, which turned out I couldn't use without running a new wire. I wanted 50 amps and I ony had a 30 amp dryer plug available. Then I had a project in mind for our WSM's, so I bought a mig welder with a spool gun to do aluminum, saw a guy using a plasma cutter in a youtube video, did some research and bought a plasma cutter, then saw a video for a tig welder, well those machines can also do stick welding, and all these can run on 30 amps, plasma and tig can also be run on 110 or 220, so yea, I dove in whole hearted like I did with bbq's... have been tinkering around with all my new machines, and by NO means am I proficient... but its fun learning. My saying is "I didn't say I was a welder, I said I have a welder"...lol Also like camping.
