1-GENERAL REMARKS

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.

1-1 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 double pulse

MIG.

- Store 100 sets of user-defined parameters, save the operator’s time.
- 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
- Fully digital wire feeding control system to ensure stable and precise wire feeding
- Fan-on demand cooling system operates when needed to extend the service life of

fan.

- Advanced digital communication interfaces for robotic system and automation system
- Digital torch with quick and convenient adjustment.

1-2 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
