Description
The Dayuri DA-MMA300 Welding Machine is an industrial-grade powerhouse designed for the most demanding welding environments. Boasting a massive 30-300A output current range, this machine is built to handle thick metal sections and high-penetration structural welds with ease. Utilizing advanced 1-2PH dual-phase technology, it offers the flexibility to operate on either 220V or 380V power supplies, making it a versatile asset for both factory floors and construction sites. Safety is paramount in the DA-MMA300, which features an integrated VRD (Voltage Reduction Device) to maintain a safe 15VDC idle voltage, preventing accidental electric shocks. The unit is engineered with Class F insulation and an IP21S protection rating, ensuring reliable operation in harsh, dusty conditions. With a high 60% duty cycle, professional welders can maintain productivity during long shifts without the machine overheating. The clear digital interface and precise control knob ensure that every weld is performed with clinical accuracy.
Features
:- Industrial 300A Power: High output capacity for heavy-gauge metal welding and structural repair.
- Dual Phase Compatibility: Seamlessly switches between 220V (Single Phase) and 380V (Two Phase) inputs.
- Enhanced VRD Safety: Reduces no-load voltage to 15VDC to ensure operator safety in damp or metallic areas.
- Digital Precision: Real-time LED current display for accurate heat management.
- Robust Duty Cycle: 60% duty cycle at 30°C allows for continuous, high-intensity welding.
- Heavy-Duty Build: IP21S rated housing protects internal inverter components from splashes and dust.
Applications
:- Industrial Construction: Welding heavy structural steel beams and columns.
- Heavy Machinery Repair: Ideal for repairing excavators, agricultural equipment, and trailers.
- Shipbuilding & Pipes: High-current arc welding for thick plates and piping systems.
- Metal Fabrication Shops: Professional production of gates, heavy grills, and industrial containers.
Usage
:- Power Input: Verify your workshop voltage (220V or 380V) and connect to a matching heavy-duty power source.
- Cable Connection: Plug the electrode holder into the positive terminal (+) and the earth clamp into the negative terminal (-) for standard MMA welding.
- Safety First: Ensure you are wearing a high-quality welding shield, heat-resistant gloves, and an apron.
- Setting the Amperage: Adjust the current (30-300A) according to the electrode thickness (e.g., 4.0mm or 5.0mm rods) using the digital display.
- Shutdown Procedure: Once the job is done, allow the fan to run for 2 minutes to cool the internal circuitry before turning off the main switch.
