Description
General Specifications:
-
Technology: IGBT Inverter with "Smart" Features
-
Welding Process: MMA/ARC (Stick)
-
Input Voltage: Typically AC 3-Phase 380V ± 15%
- Frequency: 50/60 Hz
- Output Current Range: 20-380A for MMA.
- Duty Cycle: Often around 30% at maximum amperage (at 40°C). This means it can weld for 3 minutes out of every 10 minutes at 400A before needing to cool down. At lower amperages, the duty cycle will be significantly higher.

- Rated Output Voltage: 36V (for MMA) at maximum current.
- Rated Input Current: Around 21.3A or higher depending on the load.
- Input Power Capacity: Around 13.2 KVA or 17 KVA
- Suitable Electrode Diameter (MMA): Typically 1.6mm - 5.0mm.
- Efficiency: Around 85%.
- Power Factor: Approximately 0.93-0.99.
- Protection Grade: IP21 or IP21S.
- Insulation Class: Class F or H.
- Weight: 4.5 kg.
- Dimensions: 425mm x 175mm x 315mm
Key Features:
"Smart" Inverter Technology:
-
- Adaptive Arc Force: Automatically adjusts the arc to prevent sticking and maintain a stable weld.
- Hot Start: Ensures easy arc ignition.
- Anti-Stick: Prevents the electrode from sticking to the workpiece.
- Voltage Reduction Device (VRD): Enhances safety by lowering the open-circuit voltage.
- Digital Display: For precise setting and monitoring of welding parameters.
- Overheat Protection: Prevents damage to the machine from excessive temperature.
- Overcurrent Protection: Protects the machine from overload.
- Wide Input Voltage Tolerance; can handle fluctuations in the input power.
- Generator Compatibility: They are designed to work with generators.
- Robust Design: Often built with durable materials for industrial use.
- Up-Slope Time : Controls the gradual increase of the welding current.
