Industrial-grade Hydrogen-oxygen Welding Machine

Our Industrial-grade hydrogen-oxygen welding machine, model LQJN-H2000, is a flagship unit in our lineup. It handles jewelry making, drug ampoule sealing, quartz glass tube closing, motor lead welding, enameled wire welding, transformer copper bar joining, wax repair, and steel cutting. This machine also excels at welding copper pipes for large coolers and freezers. Its high power makes it a top choice in the field. The core power is 7 kW, operating on 380V industrial voltage, with stable output. Gas output is adjustable from 0 to 2200 liters per hour, making it suitable for both batch production and fine, detailed work.

This Industrial-grade hydrogen-oxygen welding machine generates hydrogen-oxygen gas via water electrolysis, requiring only pure or distilled water. The gas mixture is produced on demand, so no high-pressure gas cylinders are stored, reducing explosion risks associated with acetylene welding. The body is made of strong, wear-resistant materials, and the internal structure is precisely engineered. Built-in flashback arrestors prevent flame backflow even in the case of incorrect operation, providing double safety. Welding produces no carbon monoxide or other harmful gases, protecting worker health while eliminating the cost and risk of storing hazardous materials. This is an environmentally friendly production method.

This welding machine delivers a flame temperature of 2800°C with highly focused heat. The affected area remains small, solving problems common with thin-wall copper pipes, such as deformation and blackened welds. The inside of the pipes comes out smooth after welding, with no grinding required, improving pass rates and production speed. Water consumption is low at 1.1 liters per hour, saving resources and supporting eco-friendly operation. Long runs do not require frequent refills. Whether welding thin pipes or large cooler parts, the machine delivers precise, steady, and efficient welds, helping workshops complete tasks effectively.
