Hi everyone, Im looking for help. I recently bought a 60watt Laser cutting machine. Got it all set up and went to fire it and NOTHING!! Looked in at the back to see what was happening with the tube and when i pulsed the power there was arcing at the connection where the live wire connects to the laser tube. there was nothing happening inside the tube, no light, no beam leaving the tube. it looks as though the power is not able to enter the tube. The machine has never been used and im just wondering do i have to get a new tube already. Any help would be great.
