I have an old swedish made plasmacutter,that works whit N2 Gas. I Would be happy to change the Torch to be air driven. Here (http://cid-ac40fb28e15b57b1.skydrive.live.com/self.aspx/.Public/plasma%20m.jpg) is a schematic off the cutter. I have been looking at This Panasonic P-80 (http://stores.shop.ebay.com/plasma-cutter-consumables_P-80_W0QQ_fsubZ242405519QQ_sidZ814396759QQ_trksidZp4634Q2ec0Q2em322) torch both the machine and hand torch because i have the tought´s that i use it whit a CNC table in the near future. I guess that i have to have one whit the pilotarc? one thing that confuses me is that it looks like the polarity on the new plasmas are different to mine that has the negative side attached to the workpiece, the air plasma cutters have the positive polarity attached to the work piece.
