All about Cutting-welding torch

[cicididi]

The conventional welding torch which has provision for a cutting attachment is characterized by a handle assembly which includes an oxygen valve and a fuel valve for adjustment of the flow of the gases into the welding tip. For cutting, the welding tip is removed and a cutting attachment installed in its place. The conventional cutting attachment includes an additional oxygen valve and a high pressure oxygen lever.

In the present invention, a metal cut welding torch is provided wherein the torch handle assembly includes the usual fuel and oxygen needle valves and in addition includes a high pressure oxygen valve for use during cutting. The cutting tip accordingly does not require either an oxygen needle valve or a high pressure oxygen lever. To prevent inadvertant actuation of the high pressure oxygen valve on the handle during welding use of the torch, a novel arrangement is provided whereby the insertion of a welding tip blocks the passage from the high pressure oxygen valve, thus effectively deactivating the valve.
