Automatic ignition type welding and cutting torch

Abstract

The invention discloses an automatic ignition type welding and cutting torch. The automatic ignition type welding and cutting torch comprises a torch body, a torch nozzle, an ignition device and a direct current discharge device arranged on the torch body. The output end of the torch body is provided with a torch nozzle connection screw thread, and the torch nozzle is arranged on the torch nozzleconnection screw thread. The ignition device comprises an insulating tube arranged on the torch nozzle in a sleeving mode, and first penetrating holes are separately formed in the two opposite side walls of the insulating tube. The axes of the first penetrating holes are parallel to the axis of the insulating tube, and the first penetrating holes are internally provided with spray points. The positive and negative poles of the direct current discharge device are separately and electrically connected to the spray points through wires in a one-to-one correspondence mode, and the spray points candischarge and ignite at one end, away from the torch nozzle connection screw thread, of the torch nozzle. By arranging an insulator, the spray points is insulated from the torch body and the torch nozzle, and the two spray points separately serve as the positive and negative poles of the direct current discharge device, so that electric sparks can be generated between the two spray points for ignition, the ignition can avoid the burn hazard to operators, and the ignition can still be smoothly performed in the case of strong wind outside.

Description

technical field [0001] The invention relates to a welding torch and a cutting torch, in particular to an automatic ignition type welding and cutting torch. Background technique [0002] The traditional welding torch or cutting torch is usually ignited by an external fire source, such as a lighter or a match, which may cause burns to the igniter when ignited, and when operating outdoors, due to strong wind Big and hard to light. When working at high altitude, holding a welding torch or cutting torch in one hand and igniting the fire in the other will also cause the danger of people or objects falling, or when working in special places, it is impossible to bring a fire source such as a lighter into it, causing problems such as inability to work. Contents of the invention [0003] The object of the present invention is to provide an automatic ignition type welding and cutting torch to solve one or more of the above-mentioned problems in the prior art. [0004] According to ...
