## Long description

The Sourcing MIG-280 MMAV2 is a professional-grade semi-automatic welding inverter engineered for high-performance metal fabrication. Utilizing advanced IGBT technology, this unit provides stable arc characteristics and efficient power management. It is equipped with a heavy-duty 4x4 wire feeder system, ensuring consistent wire delivery for demanding welding projects. Operating on a 400V power supply, the machine delivers a robust 300A output at a 60% duty cycle, making it a reliable solution for industrial environments and professional workshops.
Advantages
The primary benefit of this welding inverter is its dual-process capability, allowing users to switch seamlessly between MIG and MMA welding modes. The integrated 4x4 wire feeder mechanism significantly improves wire feed stability, reducing the risk of tangles or inconsistent welds during long production runs. With its high duty cycle and IGBT-based architecture, the device maintains thermal stability and arc precision even under continuous heavy-duty use. The inclusion of essential accessories, such as the MB24/5 torch and dedicated MMA cables, allows for immediate deployment in various metalworking scenarios.
Suitable for
Industrial metal fabrication and structural steel welding
Automotive repair and body shop applications
Maintenance and repair tasks in professional workshops
Heavy-duty construction and assembly projects
This unit may not be suitable for light-duty hobbyist projects or environments where a 400V three-phase power supply is unavailable. Due to its size and weight, it is less portable than smaller, single-phase inverter models, making it less ideal for mobile field repairs that require frequent relocation.
Key specifications

To operate the Sourcing MIG-280 MMAV2, ensure the machine is connected to a compatible 400V power source. Install the appropriate wire spool onto the D300 holder and thread it through the 4x4 feeder system. Select the desired welding mode on the control panel and adjust the voltage and wire speed settings according to the material thickness. Connect the ground clamp securely to the workpiece before initiating the arc.
What to consider before purchase
Verify that your facility has access to a 400V three-phase power connection.
Ensure your workspace is equipped for the physical dimensions of a D300 spool-compatible machine.
Confirm that the included MB24/5 torch meets the specific requirements of your welding tasks.
Always wear appropriate personal protective equipment, including a welding helmet, gloves, and flame-resistant clothing, and ensure the workspace is well-ventilated to manage welding fumes.
