Abstract

Recognizing interchangeable torch components, such as consumables, for welding and cutting torches includes determining that one or more interchangeable torch components installed in an operative end of a torch are genuine. Operational parameters for the one or more interchangeable torch components can also be determined. When the one or more interchangeable torch components are determined to be genuine, an indicator assembly can be activated to provide a first indication. When the operational parameters are implemented at a power supply connected to the torch, the indicator assembly can be activated to provide a second indication.

First claim

We claim:

1. A torch assembly for welding or cutting operations, comprising:
a torch body with an operative end configured to removably receive one or more interchangeable torch components;
a memory;
a processor that executes instructions stored in the memory so that the processor:
determines that the one or more interchangeable torch components are genuine; and
determines operational parameters for the one or more interchangeable torch components; and

an indicator assembly that provides a first indication when the one or more interchangeable torch components are determined to be genuine and provides a second indication when the operational parameters are to be implemented.

2. The torch assembly of claim 1 , wherein the processor further:
determines if the one or more interchangeable torch components are properly installed in the torch body.

3. The torch assembly of claim 2 , wherein the indicator assembly provides a third indication when the one or more interchangeable torch components are determined to be properly installed in the torch body.

4. The torch assembly of claim 2 , wherein the processor determines that the one or more interchangeable torch components are genuine and determines the operational parameters after the one or more interchangeable torch components being determined to be properly installed in the torch body.

5. The torch assembly of claim 1 , wherein the torch assembly further comprises:
a trigger, wherein the processor executes the instructions stored in the memory in response to an actuation of the trigger.

6. The torch assembly of claim 5 , wherein the processor executes the instructions in response to the actuation of the trigger after the one or more interchangeable torch components are properly installed in the torch body.

7. The torch assembly of claim 1 , wherein the processor executes the instructions in response to the torch assembly receiving power.

8. The torch assembly of claim 1 , wherein the processor further:
instructs a power supply controlling delivery of power and gas to the torch assembly to use the operational parameters determined by the processor.

9. The torch assembly of claim 1 , wherein the one or more interchangeable torch components comprise a unitary cartridge.

10. The torch assembly of claim 1 , wherein the indicator assembly:
deactivates the first indication prior to providing the second indication.

11. A system, comprising:
a torch assembly including:
a torch body with an operative end;
an indicator assembly;
a memory; and
a processor that executes instructions stored in the memory; and

a unitary cartridge that is removably coupleable to the operative end of the torch body,
wherein the processor:
determines that the unitary cartridge is genuine;
causes the indicator assembly to provide a first indication based on a determination that the unitary cartridge is genuine; and
sends a start signal to a power supply based on the determination that the unitary cartridge is genuine, the start signal causing the power supply to deliver power and gas to the torch assembly.

12. The system of claim 11 , wherein the start signal causes the power supply to automatically set parameters of the power and the gas sent to the torch assembly.

13. The system of claim 12 , wherein the processor further:
causes the indicator assembly to provide a second indication when the start signal causes the power supply to automatically set the parameters of the power and the gas.

14. The system of claim 13 , wherein the processor further:
deactivates the first indication prior to causing the indicator assembly to provide the second indication.

15. The system of claim 11 , wherein the processor further:
assesses parts-in-place for the unitary cartridge; and
causes the indicator assembly to provide a third indication based on an assessment of parts-in-place.

16. The system of claim 15 , wherein the processor further:
sends a parts-in-place signal to the power supply when the assessment of parts-in-place for the unitary cartridge determines the unitary cartridge is properly installed in the torch body.

17. The system of claim 15 , wherein the unitary cartridge includes one or more cartridge contacts, the torch body includes one or more torch contacts and the assessment of parts-in-place comprises determining whether the one or more cartridge contacts are in contact with the one or more torch contacts.

18. A method comprising:
determining that one or more interchangeable torch components installed in an operative end of a torch are genuine;
determining operational parameters for the one or more interchangeable torch components;
activating an indicator assembly to provide a first indication when the one or more interchangeable torch components are determined to be genuine; and
activating the indicator assembly to provide a second indication when the operational parameters are implemented at a power supply connected to the torch.

19. The method of claim 18 , wherein the first indication is deactivated when the second indication is activated.

20. The method of claim 18 , further comprising:
assessing parts-in-place for the one or more interchangeable torch components; and
causing the indicator assembly to provide a third indication based on an assessment of parts-in-place.
