Abstract

A consumable component for use in a plasma arc torch is provided that includes a body having a distal end face and at least one extension disposed within the distal end face. The extension is configured to maintain a predetermined torch height above a workpiece during drag cutting operations, for either manual or automated plasma cutting operations.

Claims

1. A drag cap for use in a plasma arc torch comprising:

a body having a distal end face; and

a plurality of balls disposed within the distal end face of the drag cap body.

2. The drag cap according to claim 1 comprising three balls.

3. The drag cap according to claim 1, wherein the balls are rotatable.

4. The drag cap according to claim 1, wherein the balls are a ceramic material.

5. The drag cap according to claim 1, wherein the balls are a steel material.

6. The drag cap according to claim 1, wherein the body defines a hollow cone shape.

7. A consumable component for use in a plasma arc torch comprising:

a body having a distal end face; and

at least one extension disposed within the distal end face of the body, the extension configured to maintain a predetermined torch height above a workpiece during drag cutting operations.

8. The consumable component according to claim 7, wherein the consumable component is a tip.

9. The consumable component according to claim 7, wherein the consumable component is a drag cap.

10. The consumable component according to claim 7 comprising a plurality of extensions.

11. The consumable component according to claim 10, wherein the plurality of extensions are balls.

12. The consumable component according to claim 11 comprising three balls.

13. The consumable component according to claim 11, wherein the balls are rotatable.

14. The consumable component according to claim 7, wherein the extension is a ceramic material.

15. The consumable component according to claim 7, wherein the extension is a steel material.

16. A tip for use in a plasma arc torch comprising:

a body having a distal end face; and

a plurality of balls disposed within the distal end face of the body.

17. The tip according to claim 16 comprising three balls.

18. The tip according to claim 16, wherein the balls are rotatable.

19. The tip according to claim 16, wherein the balls are a ceramic material.

20. The tip according to claim 16, wherein the balls are a steel material.
