Getting the plumbing and electrical set up in here for the new machine and thought I had better ask before aking a mistke. We are an automotive shop and as most of you probably know, there is a trend right now (maybe forever) of filling your tires with pure nitrogen instead of atmospheric. So we have a nitrogen seperator/generator in house and I was wondering. It would be just as easy to run my plasma cutter on nitrogen as on air. I know nitrogen is generally considered to be better, and since it is coming out of the unit is it totally pure, clean and dry. Can the unit run on nitrogen or are there gas speific components that have to be replaced?
