1. Those custormer who are using KCF Guide-Pin for special insulation material,
                       this technology was developed in  Japan

                   2. The air cooling systerm can increase the life of electrode and pin.

                 3. This technique requires high precision that guides a pin all the time and                                                                                                  keep it stays on the center of a hole.
