Abstract
Approaches herein provide a torch handle including a pneumatically controlled jaw operable to engage an electrode. In one approach, a system is provided for distributing gas within the torch handle, the system including a pneumatic cylinder within a main housing of the torch handle. The pneumatic cylinder is coupled to a shaft for actuating a first member of a jaw relative to a second member of the jaw. The system further includes a gas passageway through the main housing, the gas passageway extending to an exit orifice disposed within the second member. A flow controller is operable to direct a flow of a gas to either the pneumatic cylinder or the gas passageway. In one approach, the first member is actuated towards the second member when the gas is directed through the gas passageway, and actuated away from the second member when the gas is directed to the pneumatic cylinder.
