Energy saving and environmental protection:No-load energy consumption is less than 100W, compared with the traditional welding machine, energy saving 50%, suitable for stainless steel products, decoration, hardware and other industries for the use of sheet welding Security protection:Over voltage and over current automatic protection function to ensure safety during use. Continuous operation, stable performance, with automatic voltage fluctuation compensation function, improve the welding quality and safety. Portability:Small size, light weight, easy to carry and operate. High performance welding performance: The main transformer core uses high-tech nanomaterials to improve the reliability and load duration of the electronic components in the welding machine. The three-proof (waterproof, dustproof, wind erosion) air duct design enhances the durability of the welder and the adaptability of the working environment. Fan intelligent sleep function, no-load voltage is 66V-70V, suitable for welding acid electrode and alkaline electrode, cable can be extended 100-150 meters (cross-sectional area of 500 square mm, to meet various welding needs.
