I am a newbe when it comes to plasma torches. I have used Oxy-fuel for an number of years, but will now be doing a lot of work with sheet metal. I have a Hyper Dynamics Model 38, and am not impressed with it¹s manual. It appears to have been printed on a copier that needs repair. After the obligatory 4 pages of safety tips, you know the ones like, ³don¹t place the torch in your ear², there is some information on power requirements, and a parts list. About operating the system they say to keep the torch tip 1/16² off the work. In another manual from Hyper Dynamics the torch specs say working stand-off is from 0 to 1/16². If this is true why would I not just drag the tip across the work, and forget about stand-off? Another item not mentioned is average consumables life. If Im getting 3 feet of cut on 18 gage steel per tip am I suppose to assume that everything is OK? Should I expect 5000 feet of cut? The only book I have seen on plasma torches is one from our local library. Its from the early sixties, talks about using special gasses, and referrers the reader to check with the manufactures user manual about tip life. Does anyone here have some information on using a plasma torch, or a good book?
