I bought a Thermal-Dynamics Cutmaster 75 and a 300 cu ft bottle of nitrogen........ going first class so far right?
I have a 220v/ 30a circuit for my Miller 210 welder and used up one bottle of nitrogen tweaking the psi, using different tips, etc. The results were not good. Alright, I ran a new 220v/ 60a circuit and re-filled the bottle of nitrogen. The results still were awful. I called the store and eventually spoke with the factory rep. "That machine is set up for compressed air." NOW HE TELLS ME. Fortunately I have a compressor that can keep up with the plasma cutter. NOW I'M HAPPY. It really is a nice machine, once you get it set up right. The POWER I now have!!!!!!!!!!!!!!
I read about using nitrogen here and thought it would work. The boys at Air-Gas were surprised also, that it didn't. I wonder why some of you can use nitrogen & I can't ??? ........ air is fine, the problem is to find more stuff to cut.
