3. The actual input current ensures that the output matches the specified values.
4. Compact design, lightweight, high reliability, and excellent welding results.
5. All products support OEM customization to meet specific customer needs.
6. Warranty: One year for the entire unit and PCB board. We also provide spare parts worth 4% of the total order value for maintenance purposes.
Key Features:
1. Automatic protection against overcurrent, overheating, and 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 and automatic arc extinction after successful ignition.
6. Compatible with most electrodes under 5.0mm in diameter for MMA welding.
7. Suitable for welding stainless steel parts, pressure vessels, and pipelines using DC TIG welding.
8. Can weld nonferrous metals like aluminum and aluminum alloys using AC square-wave welding.
9. Dual inverter technology, pure square-wave output, concentrated heat, strong reverse cleaning capability; adjustable cleaning frequency and ratio, ideal for aluminum welding. Preset mixing ratio and frequency help protect the tungsten electrode and extend its life.
