Sep 7, 2008. #10. Hi all, The plasma torch i had was air arc type actually made in lebanon,nh. Thermal dynamics made the torch itself. Temerature of the plasma arc. is sposed to be above 30,000'F and below 50,000'F... It would cut anything. that was conductive....or at least i could find....a plasma would be good and fast at cutting cats …

Plasma is the fourth state of matter whereby a gas is electrically excited via a DC arc producing a high energy plume that can be used to melt metals and alloys. That arc can be transferred to a work piece to aid in melting or the arc can be non-transferred, or contained within the torch, thereby causing the plasmated gas plume to accomplish ...
