Hi all,

I recently purchased a new chinese 60W 28x20 Laser. I would like to preface this question with the fact that I am new to laser engraving and this is my first machine. It seems that the laser beam is in constant contact with the electrode end. It is not arcing but when viewed from above, the laser is bending toward the electrode end. I have a clean closed water system filled with five gallons of distilled water. There are no bubbles in the tubes and there is adequate flow of water. The temperature is currently at 23 degrees Celsius. Aside from moving to testing the power supply unit and electrode connections themselves can anyone shed any light on this situation? I am honestly not sure if it is an issue but I would assume to see the laser pass through the center of the electrode end. Any help would be greatly appreciated.
