A device for protection from the electron beam in manual electron beam welding in space is described. The device operation is based on short-term (0.002 s) probing with the electron beam of the surfaces being welded. When the distance from the gun to the surfaces being welded is increased above the working distance, the device lowers the beam power density to a safe level and (or) completely switches the beam off
