The R-100127 is a practical welding machine specially designed for the professionals in
the in the dental field. It allows welding two metal pieces by means of the passage of an
electrical current of high intensity during a very short time. The machine operation is
CPU controlled and therefore almost no spark is produced between the electrodes. You
can work with a wide range of stainless steel and iron wires, by simply adjusting the
working power.
