1.IGBT inverter half-bridge structure, so that the device size is smaller, lighter weight, easy to carry.
2.Simple operation interface, equipped with digital display meter, precise control of welding current, simple operation, suitable for personal, home and DIY welding.
3.2. Friendly working with wide single voltage (230V) or Bivolt (127V/230V).
3. Inbuilt the useful function for quick ARC strike, stable and continuous arc for smooth welding.
4. Inbuilt Over-heat protection, Over-Load protection, and Over-Voltage protection.
5. LIFT TIG function is optional. (If you need this function, please consult our sales in advanced.)
