Abstract

An apparatus and method for extending a plasma arc torch is disclosed. The apparatus includes a plasma torch adapter for relocating a mounting location of plasma torch consumables with respect to a plasma arc torch. The adapter is configured to be mounted between a plasma arc torch and the plasma torch consumables. The adapter is connectable to a consumable interface of the torch and includes a generally longitudinal body having a first end and a second end. The adapter includes a first connector at the first end of the body that is adapted to mate with the consumable interface. The adapter further includes a second connector at the second end of the body for mating with a set of plasma torch consumables, such that a second mounting location for consumables is established in a spaced relationship relative to the first connector, the mounting location adjacent the second connector.

Claims

1. A plasma torch adapter for relocating a mounting location of plasma torch consumables with respect to a plasma arc torch, configured to be mounted between a plasma arc torch and the plasma torch consumables and connectable to a consumable interface of the plasma arc torch, the plasma torch adapter comprising:

a generally longitudinal cylindrical body including a first end and a second end;

a first connector at the first end of the body, the first connector adapted to mate with the consumable interface of the plasma arc torch; and

a second connector at the second end of the body for mating with a set of plasma torch consumables, such that a mounting location for consumables is extended in a spaced relationship relative to the first connector along a longitudinal axis of the cylindrical body of the adapter, the mounting location adjacent the second connector.

2. The plasma torch adapter of claim 1 wherein the consumable interface accommodates consumables having a first mounting topology and the second connector accommodates consumables having a second mounting topology.

3. The plasma torch adapter of claim 1 further comprising a sensor that detects the presence of consumables mounted at the second mounting location.

4. The plasma torch adapter of claim 1 further comprising an adapter sensor mechanism that relocates a functionality of a torch sensor to the mounting location of the adapter.

5. The plasma torch adapter of claim 1 wherein the first connector receives a first set of functionalities from the plasma arc torch and the second connector transmits a second set of functionalities to the set of plasma torch consumables, the second set of functionalities including at least the first set of functionalities.

6. The plasma torch adapter of claim 1 wherein the first connector receives a first set of functionalities from the plasma arc torch and the second connector transmits a second set of functionalities to the set of plasma torch consumables, the second set of functionalities does not include all functionalities of the first set of functionalities.

7. The plasma torch adapter of claim 1 wherein the body contains at least two electrical paths from the second end of the body to the first end of the body.

8. The plasma torch adapter of claim 1 wherein a gas flow of the plasma arc torch is modified by the plasma torch adapter.

9. The plasma torch adapter of claim 1 wherein the body has a starting mechanism for contact starting a plasma arc.

10. The plasma torch adapter of claim 1 wherein the body is at least one of flexible or positionable.

11. The plasma torch adapter of claim 1 wherein the second connector is configured to connect to a second plasma torch adapter.

12. The plasma torch adapter of claim 1 wherein the plasma arc torch is a handheld plasma arc torch.

13. The plasma torch adapter of claim 1 wherein the consumable interface and the second connector are complementary.

14. The plasma torch adapter of claim 1 wherein the adapter is securable to the consumable interface to prevent rotation of the adapter relative to the torch.

15. The plasma torch adapter of claim 1 wherein the adapter has a gas input separate from a gas input from the plasma arc torch.

16. The plasma torch adapter of claim 1 wherein the plasma torch consumables and the set of plasma torch consumables are the same.

17. A plasma torch adapter for extending a plasma arc torch, configured to be mounted between the plasma arc torch and plasma torch consumables, the plasma torch adapter connectable to a consumable interface of the plasma arc torch and comprising:

a generally longitudinal cylindrical body including a first end and a second end;

a first connector at the first end of the body, the first connector adapted to receive a gas input and cutting current from the plasma arc torch; and

a second connector at the second end of the body for passing a gas output and a cutting current to plasma torch consumables, such that a mounting location for the consumables is extended in a spaced relationship relative to the first connector along a longitudinal axis of the cylindrical body of the adapter, the mounting location adjacent the second connector.

18. The plasma torch adapter of claim 17 wherein the body comprises a starting mechanism for contact starting a plasma arc.

19. The plasma torch adapter of claim 18 wherein the starting mechanism includes a spring.
