Hey how's it going I'm having a problem with my plasma cutter. From the moment it's plugged in the overheating light is on. I would really love to fix this problem and not have to buy a new plasma. I have had this machine for as long as I can remember. Any tips on how to fix this would be greatly appreciated. I've been procrastinating on just trying to just blow it out because I don't know if that will have any affect. Please let me know if I'm wrong about that.
