Description

The SHIYO MA 4400 is a powerhouse MMA (SMAW) process welder engineered for rigorous industrial applications. Built with advanced inverter technology, it combines a powerful IGBT tube to deliver a stable arc with minimal spatter. Designed for reliability in harsh environments, it features automatic under-voltage fluctuation compensation and a high 60% duty cycle at 40°C, making it the go-to solution for heavy-duty fabrication and construction.

Key Features Industrial Power: Operates on a Three-Phase 415V input, delivering a massive 20–400A output range for heavy-gauge welding.
Superior Arc Stability: Advanced IGBT technology ensures excellent stick welding performance with very little spatter.
Enhanced Welder Safety: Equipped with a VRD (Voltage Reduction Device) feature, which reduces open-circuit voltage to ensure safety in damp or humid working conditions.
Smart Protection: Built-in under-voltage and overheating protection, plus automatic compensation for voltage fluctuations.
Heavy-Duty Capacity: Supports a wide range of electrodes, from 2.6 mm to 5.0 mm in diameter.
High Efficiency: Boasts a 93% efficiency rating and a power factor of 0.85, optimizing energy consumption for industrial plants.
