I've read somewhere that if you push your gantry around with power off that it can back feed voltage to the control box and damage it. Any truth to this in the case of DynaTorch machines?
And a dumb question about grounding. I've grounded everything to it's own rod right under the machine per the manual with one exception: It shows grounding the moniter also, how in the heck do you attach a ground wire to a unit with no exterior metal parts?
