HGM Model 20 Argon Laser

For sale is an HGM model 20 Argon laser.  This system is working well but with its age the total power output has diminished but is still a little over 12 watts.  The system would need recharged if the buyer wants more than the 12 watt output.  Other than that it has been tested to work properly.  It also comes with the foot pedal, power cord and cooling hoses.
