ABSTRACT:
A gas actuated starting rod feed device for use with hand holdable oxygen cutting and/or scarfing torches. The starting rod feed device includes means for gripping and advancing a starting rod. The gripping means is operated in response to the stroke of a piston-like member which is actuated by a pulse of oxygen diverted from the main oxygen stream. The oxygen gas is vented to atmosphere at the end of the piston stroke so that the starting rod feed device is automatically reset and so that there is no pressurized oxygen present during the cutting or scarfing operation in the vicinity of the flame issuing from the torch.
