Features:
1. Reliable and energy saving: Adopting the IGBT soft switch technology, it greatly raises the efficiency andpower factor; Adopting the peak current contol technology and the protection system from over temperature, over/undervoltage and phase lacking, the machine is endowered with high reliability.
2. Multifunctional: Support MMA welding, gouging, DC TIG welding, pulse TIG welding, TIG spot welding, MAG welding, pulse MAG welding, AC/DC TIG welding. The functions can be combined in line with the requirements of the customers.
3. High adaptability of power: Can be used in 3-phase 260V-450V, suitable for field operation
4. High coherence, and function stability: Adopting the best apparatus and components, the set of welding parameter and control to welding are both realized over the software, avoid the aberrance, distortion of simulation signal, reduce the interference of other signals.
5. Rich parameter selecting: With the rapid and reliable parameter preset function, the customer can directly adjust the parameter to optimize the welding effect.
6. The friendly man-machine conversation interface: Adopting the digital meter and LCD, it can directly and quickly show the welding parameter
7. Easy to operate: Parameter ca be set over one knob and function selected over the menu, easy to operate
8. High applicability: The common welder can choose the kept parameter or the recommended parameter in the welding expert database to realize the high quality welding, while those customers with high requirements can set the parameter and control the welding progress over the front panel to meet the special welding requirements
9. Distance control: The internet and power software adjusting technology make the distance sensing, surveying and adjustment possible.
10. Distance upgrading: The widely used hardware is applied, which makes the product improvement easier, the distance upgrading of software can be realized over Internet, so as to optimize the welding performance, or add the welding function to meet the particular welding requirements of the customers
