MMA welding machine

The ZX7-400 is a high-performance 400A industrial MMA welding machine. It uses advanced soft switch technology for high efficiency and low power consumption. This machine works with 3-phase 380V power and can handle voltage changes up to ±20%.

It provides a stable arc and precise welds. The machine supports all electrode types up to 5.0mm diameter. It includes key safety features like overcurrent, overheating, and over/under voltage protection.

The digital display shows current and voltage clearly. You can preset the welding current. Special functions allow adjustment of arc-ignition current and thrust current. This prevents the electrode from sticking to the workpiece.

Weighing only 35kg, it is compact and portable with a convenient handle. An optional remote control box is available for easier operation. This machine is built for reliable performance in demanding professional environments.
