I got some portable air conditioners installed in the garage as a temporary cooling solution. They are LG 14,000 BTU Portable Air Conditioner units. I bought three of them, together they’re supposed to provide 3.5 tons of cooling, 12,000 BTUs is a ton so 42,000 BTUs makes 3.5 tons. I think I will ultimately get mini splits installed, but for now this will do. I also practiced TIG welding 1/16″ mild steel tubing. This stuff is so thin and easy to blow a hole in!
For my TIG Practice I ended up running 85A, straight polarity, and 1/16 filler rod for my best results. Have to modulate the pedal a bit and weave around a little to push the puddle. Trying to just drag/push the puddle straight was causing too many blowouts. Some agitation from a weave makes it go much cleaner and faster.
