Abstract: A torch having a replaceable trigger module is disclosed. The trigger module includes a housing defining a cavity; a trigger operatively coupled to the housing; and a printed circuit board (PCB) configured to be electrically coupled to one or more accessories. The PCB and the one or more accessories are disposed at least partially in the cavity and are coupled to the housing so that coupling the housing to a torch handle mechanically couples the PCB and trigger to the torch handle.

Abstract: A torch for an arc process operation includes a handle and a trigger coupled to the handle. The trigger includes a base segment configured to rotate relative to the handle via a pivot, as well as an extended segment coupled to the base segment. The extended segment is configured to move relative to the base segment to transition the trigger between an extended configuration and a compact configuration, the extended segment extends away from the base segment in the extended configuration, and the extended segment extends along the base segment in the compact configuration.

Abstract: An electrical connector is disclosed. The electrical connector includes a multi-diameter power pin having a proximal portion having a first diameter; an engagement portion having a second diameter smaller than the first diameter; a bearing portion having a third diameter smaller than the second diameter; and a threaded distal portion having a fourth diameter smaller than the third diameter. A receiving block having a multi-diameter through hole is configured to receive the multi-diameter power pin. The receiving block includes a plurality of gaps extending radially from the multi-diameter through hole to an outer surface of the receiving block, a receiving portion disposed between a lateral surface of the receiving block and a first gap of the plurality of gaps; and a clamping portion disposed between the plurality of gaps.

Abstract: Provided for herein is an apparatus that includes a machine-side connection housing. The machine-side connection housing includes a machine-side connection configured to provide a welding consumable or an electrical connection to a welding/cutting torch head. The apparatus also includes a fume extraction connection housing that includes a fume extraction connection to a fume extraction device. A flexible connection is arranged between the machine-side connection housing and the fume extraction connection housing. A seal that includes a first orifice is arranged between the fume extraction connection and the machine-side connection. Finally, a conduit, configured to connect the machine-side connection to the welding/cutting torch head, is arranged to pass through the first orifice, through the flexible connection and through the fume extraction connection housing to the welding/cutting torch head.
