eBay K40 CO2 Laser – New Safer Cooling Solution!


In this episode, we will be looking at the mounting brackets we designed to attach a 12 volt (DC) pump to our eBay K40 CO2 Laser as I felt uncomfortable droping a Chinese pump with 120 volts in a bucket of water. So this seems to make more sense as it moves 1.8 liters per/min and planing to use power from the laser from itself to drive the pump. There are a couple versions:

1. diy3dtech.com/co2_laser_water_pump_w-power-supply as this version comes with its own 12volt power supply so you don’ have t open the laser and do any wiring.

2. diy3dtech.com/co2_laser_water_pump_without-power-supply as this version is half the price of the first, yet you will need to come up with your own power solution.
