MMA 400HD
ARC MMA Welding Machine / Inverter Stick Welder
- Robust industrial housing with a clean, protective design. The IP23S protection rating helps protect the machine against water spray and solid objects larger than 12.5 mm
- Equipped with RILAND self-developed RICHIP chip technology for high functional integration and low processing latency, helping improve operating efficiency
- Intelligent synergic control system for easier setup and operation
- Supports MMA stick welding and Lift-TIG welding, allowing users to select the appropriate welding mode for different applications
- Adjustable Anti-Stick, Arc Force, and Hot Start functions for improved arc starting and welding control
- A patented hexagonal air duct design helps reduce dust intake and lower the risk of machine failure
- VRD (Voltage Reduction Device) helps enhance operator safety by reducing open-circuit voltage when the machine is not welding
- Built-in overcurrent, over-temperature, and overvoltage protection helps reduce downtime and maintenance costs
