ZX7-315G Pulse MMA Welding Machine | 220V/380V Dual Voltage Portable IGBT Welder
The ZX7-315G Pulse MMA Welding Machine is a high-power, high-stability inverter arc welding equipment in our MMA welder series. Built with mature IGBT single-tube main circuit technology, the machine features safe operation, strong stability and long service life. It supports full-range 220V/380V universal dual voltage, which adapts to complex and diverse power supply environments of home, workshop and outdoor construction sites.
Compared with ordinary small welders, the ZX7-315G model achieves small body with huge power. It is equipped with intelligent display system and comprehensive safety protection design, delivering stable current output, excellent welding forming effect and higher working efficiency. Lightweight and portable, it perfectly meets the needs of mobile construction, high-altitude operation and daily industrial maintenance welding.
Core Product Features
1. Advanced IGBT Single-tube Multi-board Design
Adopts professional IGBT inverter main circuit structure, with strong load capacity, stable operation and low failure rate. It ensures continuous and stable output during long-time welding, greatly improving equipment durability.
2. Full Universal Voltage Compatibility
Supports 220V single-phase, 380V single-phase and 380V three-phase power supply. No need to change wiring or add transformers, freely applicable to household electricity and industrial commercial electricity scenarios.
3. Multiple Safety Protection Mechanisms
Built-in over-temperature, over-current, over-voltage and under-voltage four-core protection functions. The machine will automatically power off and protect itself in abnormal working conditions, effectively preventing equipment burnout and ensuring construction safety.
4. Efficient Full-duct Heat Dissipation SystemEquipped with a high-speed full-duct cooling fan, which accelerates internal air convection, quickly dissipates heat generated during high-power operation, guarantees long-term high-load stable work, and extends the welder's service life.
5. Excellent Welding PerformanceFeatures stable welding current, concentrated arc force, and deep welding penetration. With strong arc resistance and bright green, easy-to-clean welding slag, it reduces post-weld polishing work and greatly improves welding quality and efficiency.
6. Intelligent Digital Display FunctionComes with a one-key start preheat prompt and working hour display function. Operators can real-time monitor equipment status and working duration, realizing standardized and intuitive welding operation.
7. Portable & Wide Application: Compact overall structure and reasonable weight design, easy to carry and move. It is specially suitable for field mobile welding, high-altitude operation, factory maintenance, and various complex construction scenarios.
