A torch device with a torch body having separate ducts for oxygen and combustion gas supply is disclosed, wherein regulating and shut-off valves are provided in the torch body in substantially opposite relationship. A common actuating device for the shut-off valves is adapted for completely closing the shut-off valve for the combustion gas before starting the closing of the shut-off valve for oxygen. All gas ducts inside the torch body are formed by bores extending parallely to each other, while connecting passages are formed by bores extending orthogonally thereto.
