MMA 500

Engineered for demanding environments, the Mechweld MMA-500 combines converter efficiency with durable construction. It features advanced inverter technology with VRD for enhanced safety, and adjustable arc force and hot-start controls for smoother arc initiation and stability. Remote current-control adds flexibility on large work sites. Well suited to workshops, construction zones, and fabrication yards, the MMA-500 provides consistent, precise welding performance—shift after shift.

Key Features & Benefits

• IGBT Full-Bridge Inverter Circuit
  Delivers efficient power and energy savings over traditional transformer welders.

• Adjustable Arc Force & Hot Start
  Helps strike and maintain a strong arc even in tough conditions—improves welding quality.

• Voltage Reduction Device (VRD)
  Lowers no-load output voltage for added safety, especially in damp or enclosed spaces.
  

• Remote Current Control (Optional)
  Lets you adjust amperage from a distance—great for large setups or difficult-to-access works.

• Multi-Protection System
  Built-in safeguards against overload, overcurrent, overheat, and voltage fluctuations.

• Broad Welding Range
  Supports electrodes from roughly 1.6 mm to 6.0 mm with strong, continuous output up to 500 A.

• Portable Yet Heavy-Duty
  Compact inverter build—roughly 17–33 kg depending on model—makes it site-friendly while industrially capable.

Ideal For

• Heavy-duty industrial stick welding in fabrication, shipbuilding, construction, and repairs

• Long welds and thick materials where high current and stable arcs are essential

• Jobs requiring safety in enclosed or wet environments

• Setups needing precise amperage control from afar or over extended workflows
