A gas powered tool (70) comprising a housing (73) and a soldering tool element (72) releasably coupled to the housing (73). A latching element (105) pivotally mounted on a pivot pin (106) in the housing (73) is retained in a non-latching state (FIG. 26) by an abutment element (102) which is urgeable into the housing (73) by the soldering tool element (72) when the soldering tool element (72) is coupled to the housing (73). The latching element (105) is spring biased in the direction of the arrow E from the non-latching state to a latching state (FIG. 27) for latching a switching element (89) in a first state to in turn retain an isolating valve (86), which supplies fuel gas from a reservoir (78) in the housing (73) to the soldering tool element (72), in the isolating state. On decoupling of the soldering tool element (72) from the housing (73), the abutment element (102) is spring urged outwardly and disengages the latching element (105). The latching element (105) pivots about the pivot pin from the non-latching state to the latching state engaging the switching element (89) in the first state, thereby retaining the isolating valve (86) in the isolating state isolating the soldering tool element (72) from the fuel gas in the fuel gas reservoir (78) in the housing (73).

A brazing system includes a touch screen display and a controller circuit board having a processor and a memory. The controller circuit board is configured to be manually set by an operator to support a single torch configuration or a multiple torch configuration. The single torch configuration includes a first integrated software having first computer-executable instructions stored in the memory and configured to execute on the processor, and the multiple torch configuration includes a second integrated software having second computer-executable instructions stored in the memory and configured to execute on the processor. The multiple torch configuration supports the independent setting up of multiple brazing torches and the simultaneous use of the multiple brazing torches by multiple users during multiple independent brazing processes. The controller circuit board is operatively connected to the touch screen display and configured to allow user interaction with the controller circuit board via the touch screen display.

A brazing system has a first gas source, a second gas source, an enclosure, a brazing torch, and a control system configured to control a ratio of the first gas source and the second gas source.

A torch includes a body that defines an interior cavity, and a fuel inlet connector secured to the body and disposed within the interior cavity. A regulator is disposed within the interior cavity and includes a regulator housing, a regulator valve and a regulator valve actuating device. An intake stem is secured to one of the fuel inlet connector and the regulator housing, and defines an intake flow passage. A burn tube is coupled with the body and defines a burn tube flow passage. A trigger is pivotally coupled with the body. The regulator valve opens as the trigger pivots between an off position and a full flow position, permitting a user to initiate and vary a flow of hydrocarbon fuel to the burn tube flow passage when the intake flow passage is in fluid communication with a source of hydrocarbon fuel, by varying the position of the trigger.

Embodiments of brazing systems are disclosed. In one embodiment, a brazing system includes a controller circuit board (controller) having a processor and a memory. The system also includes a fuel gas input, a fuel gas output, an oxygen/air gas input, and an oxygen/air gas output. The system further includes a touch screen display and a foot pedal, each operatively connected to the controller. The controller is configured to store multiple jobs of flame presets in the memory. Any job can be called up from the controller and the flame presets can be cycled through in response to tapping the foot pedal. Each job corresponds to a sequence of joint brazings to be performed on a braze assembly and includes a plurality of selectable flame presets. Each flame preset defines a flame setting based on a flow rate of a fuel gas and a flow rate of an oxygen/air gas.
