I purchased this laser machine directly from the manufacturer in the UK in June 2024; it is an excellent machine that has barely been used and is in pristine, like-new condition. I still have the original shipping box. It does not require water refilling, features a digital display with 100 memory slots, and operates on 110 volts. Specifications include a Leica 10X stereo microscope, high-brightness LCD shutter, internal joystick within the welding chamber, powerful LED lights, 100W average power, 6.5 kW peak power, and 165 J energy..              Shipping within the USA.         No returns accepted.
