2. Excellent Structure: Portable edm is convenient to carry due to small size and light weight, and shows its special superiority for large work pieces. Working head is separated from the machine and could rotate in any direction, which is helpful for complex machining;

3. Portability: Light weight; Small size; Carrying handle on the top of the power case;

4. Convenient Operation: The magnetic base could attract on work pieces to finish processing easily;

5. Vibrate work head: Vibrate of the electrode, greatly improved the processing efficiency;  

6. Automation: Auto feed; Depth setting(Stop at a specific depth); Alarm and auto retract;           

7. Economical and Convenient: The working liquid is ordinary tap water; power consumption is moderate; the inlet pipe is detachable;

8. Wide Processing Range: Broken taps and drills (conductive material) above Ø2mm (Ø2mm is included);

9. Long Working Time: A cooling fan installed ensures the ventilation, which keeps the machine working continuously.
