Abstract
Arrangement in a cutting burner to clean and cool the cutting oxygen channel in the burner nozzle during the heating procedure. The arrangement comprises a connection line with an incorporated throttling member between the heating oxygen gas channel and the cutting oxygen gas channel; and a check valve member in the cutting oxygen gas channel. The valve is situated thus that the portion of the heating oxygen gas flow which passes through the cutting oxygen gas passage is permitted to pass only in the direction towards the nozzle orifices.
