Just sharing a point of general interest.
I was curious about the energy usage of my 700 x 500 China Blue/Grey Laser.
I have a SPT TR75 tube on the the original 60W LPS and run a dedicated Hyundai Super Silent air compressor for the Ultimate Air Assist. Cooling is with water tank and Pond pump. My system is 230V
For the purpose of the test I ran a cut cycle at 70% power (22mA).
The Total W column are cumulative totals and as shown full total is with everything running is 1,245W
Once the compressor is up to pressure and switches off the total drops to 596.4W.
