  1. I only have one complaint about this video... That's NOT an Air-Arc lol An Air Arc is a totally different, and even hotter, tool.. Basically its a hollow, copper coated, carbon electrode that goes into a special electrode holder which blows high pressure air through the hollow core. It basically looks like a large stick welder holder and electrode. It then connects to a LARGE arc welder power supply. You strike an arc just like with an stick welder, and it melts a weld pool just the same (though with hundreds of amps), and then the high pressure air blows the molten metal away. As you can imagine, it creates a BIG cloud of sparks! Quite fun to operate, very noisy, but beautiful curtains of molten steel everywhere. What they were using here was a plasma cutter, which is also an awesome tool, but much more delicate and precise. Like the difference between using a scalpel and a chainsaw to cut the turkey lol
