Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for improving the flow control of a shielding gas in a welding unit is described which uses feedback from at least one of a mass flow controller, a pressure sensor and a valve position sensor to regulate shielding gas flow through a controller.
