1. Ultra high series: high frequency, able to heat Φ 0.1mm work-piece.
2. Small size, light weight, low failure rate and conservation of energy. (which can save the power by 70% as compared with glass-ceramic vacuum tube high frequency heating machine)
3. It can ensure the solid welding point which is pleasing and delicate in appearance, integral geometric configuration, perfect surface grain, complete crystal structure of internal metal part, limited annealing range and elimination of obvious weld knot.
4. About ten types fault protection and display of over-current, over-voltage, water shortage and phase missing can provide higher reliability and durability.
5. It is applied to the welding of coupler and inserts used in metal glass manufacturing as well as electric appliance and electronics industries, non-contact welding of internal parts of small-size relays, high-pressure refrigerating parts, headwear decorations, metal ornamental articles an art wares.
