Miscellaneous

Used Coherent Innova ion laser and power supply in non-operating condition. We connected water and powered up the system and it was determined that the plasma tube is 40 Vdc over-pressure. We are selling the unit for parts or repair. While the unit was powered up we wrote down most of the readings on the control pendant and they are listed below. THIS ITEM IS BEING SOLD AS-IS!

• Tube model 160-867-00A, mfg 1990
• Power supply:
• Watercooled, 2.2 GPM
• Remote control pad
