ZX7 Series Arc/MMA Welding Machine Production:Our company produces the ZX7 series inverter welding machine, a high-efficiency and energy-saving DC power source. It uses IGBT technology with advanced PWM 20KHz pulse-width modulation to convert 50Hz power frequency into 20KHz high-frequency, then rectifies it through a voltage-dropping resistor for efficient DC output.
Key Features:
1. Simple circuit design with strong anti-interference capability.
2. Adjustable arc force based on cable length, suitable for long-distance welding.
3. Adjustable striking current, ideal for different thicknesses of workpieces.
4. Digital ammeter display, allowing precise pre-setting of welding current.
5. Compatible with various electrodes including Φ2–Φ6 acidic and refractory steel.
6. Suitable for welding Stainless Steel, carbon steel, and alloy steel.
7. Carbon arc air gouging function available for machines above 500A.
8. High-frequency inverter, compact size, lightweight, and energy-efficient.
