Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically to a welding torch with switchable nozzle type. Background Technology

[0002] Currently, welding torches on the market are mainly divided into two types: those requiring pure oxygen for combustion (i.e., oxygen-based welding torches) and those requiring only air for combustion (i.e., oxygen-free welding torches). Each has its advantages and disadvantages. The advantage of oxygen-based welding torches is their high flame temperature, making them suitable for both welding and cutting. The disadvantage is that the oxygen is quickly depleted, resulting in a short working time; once the oxygen is exhausted, the torch becomes unusable. The advantages of oxygen-free welding torches are their portability, light weight, and long operating time per fuel cylinder, making them suitable for low-volume tasks such as air conditioner installation and maintenance. The disadvantage is that the temperature is not high enough to weld large workpieces. Utility Model Content

[0005] Preferably, the oxygenated or oxygen-free nozzle is detachably installed at the front end of the fixed connector via a threaded connection.

[0006] Preferably, the oxygen-free nozzle includes a metal oxygen-free nozzle pipe and an ignition switch installed on the oxygen-free nozzle pipe, while the oxygen-enriched nozzle is a metal bent nozzle pipe.

[0007] Preferably, the oxygen regulating valve and the gas regulating valve are arranged perpendicularly to each other on the periphery of the fixed joint.

[0008] Preferably, the oxygen regulating valve is a blue regulating valve, and the gas regulating valve is a red regulating valve.
