Abstract

In certain embodiments, a system includes a master node device. The master node device includes communication circuitry configured to facilitate communication with a welding power supply unit via a long-range communication link, and to facilitate wireless communication with one or more welding-related devices via a short-range wireless communication network. The master node device also includes control circuitry configured to associate the one or more welding-related devices with the short-range wireless communication network. The master node device further includes means for manually initiating association of the one or more welding-related devices with the short-range wireless communication network.

Claims (33)

1. A system, comprising:

a master node device comprising:

communication circuitry configured to facilitate communication with a welding power supply unit via a long-range communication link, and to facilitate wireless communication with one or more welding-related devices via a short-range wireless communication network;

control circuitry configured to associate the one or more welding-related devices with the short-range wireless communication network; and

means for manually initiating association of the one or more welding-related devices with the short-range wireless communication network, wherein the means for manually initiating association of the one or more welding-related devices with the short-range wireless communication network comprises a synchronization mechanism that initiates association of a welding-related device with the short-range wireless communication network when activated simultaneously with a synchronization mechanism of the welding-related device.

2. The system of claim 1 , wherein the control circuitry is configured to allow association of the one or more welding-related devices with the short-range wireless communication network only if the welding-related devices include authorization credentials that indicate the welding-related devices may be used with the master node device.

3. The system of claim 2 , wherein the authorization credentials include at least a media access control (MAC) address and a function code of the welding-related devices.

4. The system of claim 1 , wherein the long-range communication link comprises a wireless communication link having a transmission range of approximately 300 feet or more from the master node device to the welding power supply unit.

5. The system of claim 1 , wherein the short-range wireless communication network comprises a wireless communication network having a transmission range of approximately 20-25 feet from the master node device.

6. The system of claim 1 , wherein the one or more welding-related devices comprise a welding wire feeder.

7. The system of claim 1 , wherein the one or more welding-related devices comprise a welding torch.

8. The system of claim 1 , wherein the one or more welding-related devices comprise a welding helmet.

9. The system of claim 1 , wherein the one or more welding-related devices comprise a welding pendant.

10. The system of claim 1 , wherein the one or more welding-related devices comprise a welding foot pedal.

11. The system of claim 1 , wherein a welding-related device of the one or more welding-related devices comprises the master node device.

12. The system of claim 1 , wherein the communication circuitry includes radio frequency (RF) transmitters and sensors.

13. The system of claim 1 , wherein the synchronization mechanisms of the master node device and the welding-related device each comprise buttons.

14. A method, comprising:

manually initiating association of one or more welding-related devices with a short-range wireless communication network having a master node device functioning as a router and prioritization controller for the short-range wireless communication network, wherein manually initiating association of a welding-related device with the short-range wireless communication network comprises activating a synchronization mechanism on the welding-related device and simultaneously activating a synchronization mechanism on the master node device;

associating the one or more welding-related devices with the short-range wireless communication network;

wirelessly communicating between the one or more welding-related devices and the master node device via the short-range wireless communication network; and

communicating between the master node device and a welding power supply unit via a long-range communication link.

15. The method of claim 14 , comprising associating the one or more welding-related devices with the short-range wireless communication network only if the welding-related devices include authorization credentials that indicate the welding-related devices may be used with the master node device.

16. The method of claim 15 , wherein the authorization credentials include at least a media access control (MAC) address and a function code of the welding-related devices.

17. The method of claim 14 , wherein the short-range wireless communication network comprises a wireless communication network having a transmission range of approximately 20-25 feet from the master node device, and wherein the long-range communication link comprises a wireless communication link having a transmission range of approximately 300 feet or more from the master node device to the welding power supply unit.

18. The method of claim 14 , wherein the one or more welding-related devices comprise a welding wire feeder, a welding torch, a welding helmet, a welding pendant, or a welding foot pedal.

19. The method of claim 14 , wherein a welding-related device of the one or more welding-related devices comprises the master node device.

20. The method of claim 14 , wherein the synchronization mechanisms of the master node device and the welding-related device each comprise buttons.

21. A wireless communication network, comprising:

one or more welding-related devices, wherein the one or more welding-related devices comprise a welding wire feeder, a welding torch, a welding helmet, a welding pendant, or a welding foot pedal;

a welding power supply unit configured to convert power from a power grid to power for a welding operation performed using the one or more welding-related devices; and

a master node device configured to facilitate wireless communication between the one or more welding-related devices and the master node device via a short-range wireless communication network, to facilitate communication between the master node device and the welding power supply unit via a long-range communication link, and to associate a welding-related device with the short-range wireless communication network upon simultaneous manual activation of a synchronization mechanism on the welding-related device and a synchronization mechanism on the master node device.

22. The wireless communication network of claim 21 , wherein the synchronization mechanisms of the master node device and the welding-related device each comprise buttons.
