1. Utilizes inverter technology with IGBT dual modules to significantly reduce energy consumption.
2. Transformers and reactors are wound with copper wire for superior performance and durability.
3. The actual input current matches the specified value, ensuring consistent performance.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. All products are available for OEM customization.
6. Warranty: One year for the entire unit and PC board. We also provide spare parts worth 4% of the total order value for maintenance purposes.
Key Features:
1. Automatic protection against overcurrent, overheating, over/under voltage.
2. Supports AC/DC square-wave TIG welding, DC TIG welding, and MMA welding.
3. Compact size, light weight, high efficiency, energy-saving, and strong voltage adaptability.
4. In TIG welding, the up/down slope of welding current is adjustable, with pre-gas and delayed gas functions.
5. HF auto arc strike, automatically extinguishes after successful arc ignition.
6. For MMA welding, compatible with most electrodes with a diameter under 5.0mm.
7. With DC TIG welding, it can weld various stainless steel components, pressure vessels, and pipelines.
8. With AC square-wave welding, it can handle nonferrous metals like aluminum and aluminum alloys.
9. Uses inverter technology twice for pure square-wave output, concentrated heat, strong reverse clearance capability; cleaning frequency and ratio can be adjusted for better deoxidation in aluminum welding. Preset mixing ratio and frequency protect the tungsten electrode and extend its life.
10. Can be equipped with a remote control box for easy operation and improved convenience.
