Abstract

Apparatus, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

First claim

What is claimed is:

1. A welding torch, comprising:
a nozzle including a tip-retention device; and
a contact tip retained by the tip-retention device, wherein the tip-retention device comprises a gas channel in a sidewall of the tip-retention device, the tip-retention device configured to direct gas radially towards the contact tip, with respect to an axis of the contact tip, via the gas channel.

2. The welding torch according to claim 1 , wherein the tip-retention device is configured to receive a gas diffuser and the contact tip, and wherein the gas diffuser includes a seat with a stepped profile that is configured to interface with a stepped profile of the contact tip.

3. The welding torch according to claim 1 , wherein the tip-retention device includes a locking taper configured to interface with a taper of the contact tip.

4. The welding torch according to claim 1 , wherein the gas channel of the tip-retention device is configured to direct the gas radially away from the contact tip before directing the gas towards the contact tip.

5. The welding torch according to claim 4 , wherein the tip-retention device comprises a tip-retention wall configured to direct the gas radially away from the contact tip.

6. The welding torch according to claim 5 , wherein the tip-retention device comprises an annular rim forward of the tip-retention wall, the annular rim having a leading edge that is configured to direct the gas towards the contact tip.

7. The welding torch according to claim 6 , wherein the gas channel of the tip-retention device comprises a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall, the second side of the tip-retention wall being closer to the annular rim than the first side, wherein the leading edge of the annular rim is configured to protect the gas channel of the tip-retention device from welding spatter.

8. A nozzle for use with a welding torch, comprising:
a tip-retention device having a sidewall and a gas channel in the sidewall; and
a contact tip retained by the tip-retention device, wherein the tip-retention device is configured to direct gas radially towards the contact tip, with respect to an axis of the contact tip, via the gas channel.

9. The nozzle according to claim 8 , wherein the tip-retention device is configured to receive a gas diffuser and the contact tip, and wherein the gas diffuser includes a seat with a stepped profile that is configured to interface with a stepped profile of the contact tip.

10. The nozzle according to claim 9 , wherein the tip-retention device includes a locking taper is configured to interface with a taper of the contact tip.

11. The nozzle according to claim 8 , wherein the gas channel of the tip-retention device is configured to direct the gas radially away from the contact tip before directing the gas towards the contact tip.

12. The nozzle according to claim 11 , wherein the tip-retention device comprises a tip retention wall configured direct the gas radially away from the contact tip.

13. The nozzle according to claim 12 , wherein the tip-retention device comprises an annular rim forward of the tip-retention wall, the annular rim having a leading edge that is configured to direct the gas towards the contact tip.

14. The nozzle according to claim 13 , wherein the gas channel of the tip-retention device comprises a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall, the second side of the tip-retention wall being closer to the annular rim than the first side, wherein the leading edge is configured to protect the gas channel of the tip-retention device from welding spatter.

15. A contact tip retention device for use with a welding torch, comprising:
a sidewall encircling a hollow interior;
a tip-retention wall attached to the sidewall, wherein the tip-retention wall is configured to retain a contact tip; and
a gas channel defined by at least one slot in the sidewall that extends radially with respect to an axis of the contact tip, the gas channel configured to allow gas to flow radially around the tip-retention wall with respect to the axis of the contact tip.

16. The device according to claim 15 , wherein the gas channel comprises a first slot on a first side of the tip-retention wall and a second slot on a second side of the tip-retention wall.

17. The device according to claim 15 , wherein the tip-retention wall includes a locking taper configured to interface with a taper of the contact tip so as to retain the contact tip within the bore, and wherein the tip-retention wall is configured to direct the gas radially away from the contact tip.

18. The device according to claim 16 , wherein the device further includes an annular rim at the leading edge of the device, wherein the annular rim is configured to direct the gas towards the contact tip, and wherein the annular rim is configured to protect the channel from welding spatter.

19. The device according to claim 15 , wherein the tip-retention wall is configured to protect the channel from welding spatter.

20. The device according to claim 15 , wherein the device is configured to engage a gas diffuser of the welding torch using at least one of a screw thread or a step in the sidewall, wherein the device is configured to direct gas from the gas diffuser towards the contact tip.
