40NL/min 95%-99.999% Nitrogen Gas Generators for Laser Welding with PLC Control
Product Description
Nitrogen Generation System for Laser Welding
High Purity • High Stability • Intelligent Control
Our ZHN Series Nitrogen Generators are specially designed for laser welding applications, providing stable, high-purity nitrogen with precise flow control. Built with advanced PSA (Pressure Swing Adsorption) technology, intelligent PLC control, and robust filtration, they ensure consistent protection of weld seams, oxidation prevention, and improved welding quality.
Key Features
High Purity Output: Adjustable nitrogen purity from 95% to 99.999% to suit various welding needs.
Steady Flow Rate: Multiple models available — 20 NL/min, 40 NL/min, 60 NL/min — to match different production capacities.
Intelligent PLC Control: Integrated 7-inch touch screen with multi-language support for easy operation.
Standard Triple Filtration System: Ensures ultra-clean nitrogen output by removing oil, dust, and moisture.
Automatic Drainage: Reduces manual maintenance and prolongs equipment lifespan.
Compact Design: Space-saving vertical structure, ideal for workshop environments.
Global Power Compatibility: AC 100–250 V, 50/60 Hz.
Applications in Laser Welding
Protective Atmosphere: Nitrogen shields the molten pool, preventing oxidation and discoloration.
Welding Quality Enhancement: Improves seam smoothness and strength.
Versatile Use: Compatible with handheld and automated laser welding machines in industries such as stainless steel fabrication, electronics, and precision instruments.
