Features:

1. Oxidation-Free Welding Ensures System Cleanliness: The hydrogen-oxygen flame has reducing properties, producing no oxide residues during welding, preventing impurities from clogging capillary tubes and compressors, and ensuring long-term stable operation of the refrigeration system.
2. Small Heat-Affected Zone Protects Surrounding Components: Highly concentrated and precise flame delivers heat only to the welding area, without damaging rubber seals, plastic coatings, and insulation materials near the piping.
3. No Flux Required, Eliminating Corrosion Risk: No flux is needed during welding, leaving no corrosive residues, reducing the risk of pipe corrosion and system leakage, and improving product reliability.
4. On-Demand Production Eliminates Safety Hazards: On-demand gas production with no storage of high-pressure flammable gases such as acetylene or oxygen, eliminating safety risks associated with cylinder storage and transportation in factories.
5. Energy-Efficient & Cost-Reducing: Only water and electricity are consumed; compared to traditional acetylene-oxygen welding, overall operating costs are significantly reduced, with no need for frequent cylinder changes, improving production line efficiency.
