Arc Air Gouging

[powerstroke444e]

I use a plasma alot for scrapping, its fast and cheap to run. Just get the ground clamp to make contact and away I go. On real rust stuff I use a gas powered concrete saw with abrasive blade

Its not advertised as able to cut rock but I suppose its possible. You can cut glass with a plasma cutter by laying sheetmetal over it and cutting through the sheetmetal.

I remember reading about the Airarc being used for burning deadbolts and hinges when doing forced entries on drug houses.

Another cool one to check out is Arc Air Exothermic Slice process. We used one of these to pierce holes in a boulder so we could break it up with a sledge hammer. It will cut anything or any combination of things like steel in concrete or rock or even glass. Nearly as messy as Carbon Arc but cuts anything. Fire departments are now using these because they can spray water on the arc and it cuts without sparks. They can remove the roof on a car 10x faster than the jaws of life. All it is is a special alloy rolled semi hollow rod that you hook up to 80 psi oxygen and it has a striker to start the arc. As long as you hold the trigger it will never go out until the rod is gone. U tube it. its cool. :thumbsup:

Yep Slice Torch cuts or actually bores into rock. Most Bridge constuction / demolition crews use Slice to cut I beams in Concrete. Works well but it does add to the crap flying around in a molten state. At a shows we used to put aluminum tape on both sides of a piece of glass and it cut it ok with Plasma. Then one day a piece popped off and a kid got a minor burn and that was it for showing glass with plasma.
