This series of power sources apply IGBT soft switch inverter technology. Its internal control system
applies digital signal processor which ensures quick response to any change during the welding
process so as to achieve precise control of welding process and ensure optimal welding results.
Power source features
This series of power sources are microprocessor controlled and apply MCU + DSP control technology
to improve the control precision. The strong ability of arc self-adjustment ensures a highly stable
welding current against grid fluctuation and arc length change to get optimal results.
Highlights as follows:
- User friendly interface, synergic, easily control;
- Embedded welding expert database, automatic intelligent combination of parameters
- To achieve beautiful ripple pattern of welding seam with the function of Pulse TIG
- Perfect functions of starting arc and reducing melting ball while stopping arc
- Special 4-step mode is suitable for welding metal with good thermal conductivity, with
perfect welding quality when starting arc and stopping arc
- Multiple protection functions
- TIG torch with quick and convenient adjustment of welding current at Torch handle
Functional principle
This series of power sources adopt IGBT soft switch inverter technology to improve the dynamic
response rate and make the machines with small size and light weight. The control circuit's closed-loop
control makes the power source enjoy strong ability against power grid fluctuation and perfect welding
performance. The schematic diagram is as shown in Fig. 1-2-1:
