Steve, I've dealt with plasma generators before, in my case atmospheric plasma for cleaning. Unless the plasma wand is under some form of robotic control I would not think this is not machinery. And in my view it is not an arc welder. What I used in the past was use EN 61000-6-2 and EN 61000-6-4 for Industrial and for Group 2 Class A invoking the clause "for treatment of material". If you use IEC 61010-1 for the safety portion, you are then required to use IEC 61326-1, which once again refers back to the same family of test standards with various tweaks to the test levels.
