Description
The iWELD MMA-401 is a powerful 400A, three-phase 380V stick-electrode welding machine engineered using the latest digital inverter technology. Designed for industrial reliability, the MMA-401 delivers exceptional welding performance while maintaining a compact, lightweight structure with a single-PCB design for enhanced durability and mobility.
This machine consistently produces clean, high-quality welds and performs exceptionally well with both basic and rutile electrodes. Its built-in welding assist features—anti-stick, hot-start and arc-force—ensure smooth arc initiation, improved stability, and reduced spatter, making it suitable for both professional welders and advanced DIY users.
For additional safety, the MMA-401 includes an integrated Voltage Reduction Device (VRD), which automatically reduces output voltage when the machine is idle, helping to prevent accidental electric shock in demanding work environments.
