Abstract
A semi-automatic brazing apparatus having a brazing wire feeding apparatus containing a brazing wire feed mechanism a controller, and a user input device. The brazing wire from a brazing wire source is continuously drawn from the source through the apparatus via the feeding mechanism and is directed towards a brazing gun for a semi-automatic brazing operation.
Claims13
A brazing apparatus comprising:
- a brazing wire feeding apparatus,
- a supply of brazing wire wherein the brazing wire is fed through the brazing wire feeding apparatus,
- a brazing wire gun through which the brazing wire passes, said brazing gun having a trigger portion and a memory switch, said trigger portion includes a displacement sensitive potentiometer;
- and
- a control device which controls the feeding of the brazing wire through the feeding apparatus based upon input from a user input device positioned on at least one of the brazing wire feeding apparatus and the brazing wire gun,
- wherein said control device has at least one memory space, said memory switch being configured with said at least one memory space for recording at least one brazing parameter to said memory space, the at least one brazing parameter including a trigger pressure sensitivity.

A semi-automatic, pre-programmable brazing apparatus comprising:
- a brazing wire feeding apparatus,
- a supply of brazing wire wherein the brazing wire is fed through the brazing wire feeding apparatus,
- a brazing wire gun through which the brazing wire passes, and
- a control device for preprogramming a plurality of brazing operations, said control device controls the feeding of the brazing wire through the feeding apparatus based upon input from a user input device positioned on at least one of the brazing wire feeding apparatus and the brazing wire gun,
- wherein said brazing wire gun comprises a trigger portion to activate said wire feeding operation, said trigger portion includes a displacement sensitive potentiometer,
- wherein said trigger portion controls said wire feeding operation based on the movement of said trigger portion in a non-linear relationship,
- wherein each brazing operation is defined by at a plurality of brazing parameters including trigger pressure sensitivity and at least one of a diameter of said brazing wire, a material of said brazing wire, a wire feed speed for said brazing wire and a duration of a wire feeding operation can be input by said user input device, and
- wherein said control device comprises at least one memory space configured with said user input device to store said plurality of brazing parameters to preprogram said brazing apparatus for semi-automatic operation.
