US 2019/0160573 A1 · APPARATUS AND METHOD FOR BRAZING

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.
