How to Wire and Current-Calibrate a Reci W2 90W Tube
Precise high-voltage wiring and milliampere meter calibration are vital for beam longevity:
Solder & Insulate Positive Anode (+)
Strip high-voltage red lead from power supply. Wrap tightly around the tungsten pin at the rear anode. Solder cleanly and slide high-dielectric silicone tubing over the joint with silicone sealant.
Wire Negative Cathode Through Meter
Connect the front negative cathode wire through an analog 0–30mA DC panel meter in series before terminating to the power supply return ground.
Purge Air Bubbles from Cooling Jacket
Run CW-5200 chiller with distilled water. Ensure water enters the lower port and exits the upper port. Gently rotate the tube until zero trapped air bubbles cling to the internal spiral glass jacket.
Calibrate Ruida Controller Max Power %
Set machine to pulse at 100% test power. Observe analog mA meter needle. Adjust the potentiometer on the Reci DY13 power supply until 100% software power corresponds to exactly 24.0 mA.
Technical & Field Service FAQs
What happens if I run a Reci W2 above 24mA?
Running a Reci W2 tube above 24mA causes rapid sputtering of the internal platinum-catalyst cathode coating and thermal stress on the output coupler mirror. Exceeding 25mA can cut tube lifespan from 10,000 hours down to fewer than 500 hours.
What power supply is matched for Reci W2?
The Reci DY13 is factory-engineered specifically for Reci W2 and W4 tubes. It provides the exact 19kV striking voltage and fast current-limiting response needed to avoid resonant optical distortion.
Can I use tap water in my laser chiller?
NO! Tap water contains dissolved minerals and chlorine that conduct high-voltage electricity, cloud the internal glass water jacket, and cause algae growth that absorbs 10.6µm laser radiation. Always use pure distilled or deionized water.
