Hi, I am considering buying the pm45 for my cnc table but have a few questions.
1. is this a high frequency unit or have high frequency start?
2. if I get the unit with hand torch can I plug into the cnc port to activate the torch on/off? if not and I run wires in the handle will this void my warranty?
3. I don't see a earth ground lead on the unit is it ok to earth ground my table?
thks scott
