CO2 Gas Flow Regulator GH-355 YQT-731 YQT-341 for MIG MAG Welding Machine
This industrial CO2 gas flow regulator is professionally developed and manufactured for MIG and MAG welding equipment. Adopting a high-quality forged brass body and precision pressure control structure, it delivers stable gas pressure and flow output throughout the entire welding process. Effectively solving issues of unstable air supply, excessive spatter, and poor weld formation, it is a standard essential accessory for industrial gas-shielded welding. The product fully complies with ISO 5171, ISO 2503, and EN 562 international standards, featuring strong environmental adaptability and a long service life.
Core Features & Advantages
- Precise Gas Control: Stepless adjustable outlet pressure and flow rate ensures uniform and stable shielding gas supply, avoiding welding defects caused by unstable gas flow.
- Premium Brass Forged Body: Integral forged brass structure without welding seams, featuring high strength, anti-pressure, corrosion resistance and durable performance.
- Effective Welding Quality Improvement: Stable gas isolation greatly reduces welding spatter, prevents air hole and oxidation problems, and makes weld seam smoother and more beautiful.
- High-precision Filtration System: Equipped with sintered metal inlet filter to effectively filter gas impurities, ensure clean gas output and protect welding torch and machine core parts.
- Clear Dual-scale Gauge: Bar/psi dual-scale design with unbreakable lens, intuitive reading, compliant with EN 562 safety standard.
- Wide Environmental Adaptability: Normal working at -10℃ to +60℃, suitable for factory workshops, outdoor construction and other harsh working conditions.
- Strong Compatibility: Supports pure CO2 gas and Ar-CO2 mixed gas, perfectly matching all kinds of mainstream MIG/MAG welding machines.
Wide Application Scenarios
Ideal for all MIG/MAG gas shielded welding work, widely used in metal processing, automotive manufacturing, hardware production, steel structure welding, pressure vessel processing, engineering machinery and other industrial fields.
