Abstract
A thermal cutting machine and a cutting method using the same are described, which employ a simple, long-life torch hood for effectively shutting off spatter, the torch hood enabling easy supervision of the cut condition of a workpiece and easy replacement of the consumable parts of the torch. In the thermal cutting machine for cutting a metal by a plasma arc or laser beam generated from the torch, a hood liftable by an actuator is disposed so as to surround the torch and a control unit is provided for giving an instruction to the actuator to lower the hood to a torch-shielding position.
