---
1. Utilizes inverter technology with IGBT dual modules for energy efficiency.
2. Reactors and transformers are made with copper windings for better performance.
3. The actual input current matches the specified value for accurate operation.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. Fully customizable for OEM orders.
6. Warranty: One year on the entire unit and PC board, with spare parts worth 4% of the total value for maintenance.
Key Features:
1. Strong arc self-adjustment for stable welding
2. Supports frequent welding with minimal spatter and high metal melting efficiency
3. Low distortion and fine weld seams
4. Protection against phase loss, overtemperature, overcurrent, and voltage fluctuations
5. Capable of welding thin low-carbon steel and low-alloy frameworks using solid-core wires (Φ0.8mm and Φ1.0mm)
6. Ideal for use in automobile manufacturing, small part processing, upholstery, and maintenance
7. Operates efficiently under ±20% voltage fluctuation
8. Supports MMA/MAG welding
