Description
The Dayuri DA-MMA400 Welding Machine is an industrial-grade powerhouse engineered for the most rigorous metalworking environments. Boasting a massive 30-400A output range, this machine is specifically designed for high-penetration structural welding and heavy-gauge metal fabrication. Its unique multi-phase (1-2-3PH) capability allows it to operate seamlessly on both 220V and 415V power supplies, providing unmatched flexibility for factory floors, shipyards, and large-scale construction sites. Equipped with advanced IGBT inverter technology, the DA-MMA400 ensures a stable arc even under fluctuating loads. Safety is a core feature, with an integrated VRD (Voltage Reduction Device) that drops the idle voltage to a safe 15VDC to protect the operator. With a robust 60% duty cycle, IP21S protection, and Class F insulation, this machine is built to deliver consistent performance during high-intensity industrial shifts. The digital interface provides real-time current monitoring, allowing for clinical precision in every weld.
Features
:- Industrial 400A Output: Massive power capacity for welding thick structural steel and heavy machinery.
- Multi-Phase Versatility: Compatible with 220V and 415V (Single, Double, or Triple Phase) inputs.
- Integrated VRD Safety: Advanced voltage reduction technology keeps the operator safe from electric shocks during idle periods.
- High Duty Cycle: 60% rated duty cycle at 30°C enables continuous operation for professional industrial use.
- Smart Digital Display: High-visibility LED screen for precise amperage control and setting.
- Rugged Construction: IP21S rated housing with forced air cooling for durability in harsh workshop conditions.
Applications
:- Heavy Structural Engineering: Welding beams, girders, and large steel frameworks.
- Shipbuilding & Maritime: Ideal for thick plate welding and heavy-duty marine repairs.
- Mining & Earthmoving: Repairing excavators, buckets, and industrial mining equipment.
- Large Fabrication Shops: Production of industrial containers, heavy gates, and factory infrastructure.
Usage
:- Power Setup: Confirm your site voltage (220V or 415V) and ensure the machine is connected to a properly grounded industrial power outlet.
- Cable Attachment: Connect the electrode holder to the positive (+) terminal and the earth clamp to the negative (-) terminal for standard DCEP welding.
- Safety Gear: Ensure the use of an auto-darkening welding helmet, leather gloves, and protective clothing before striking an arc.
- Amperage Setting: Use the digital control knob to set the amperage (up to 400A) based on the thickness of the electrode and material.
- Cool Down: After finishing a heavy weld, allow the internal fan to run for several minutes to cool the inverter components before switching off.
