Product Features： 1. Total efficiency is greater than 90% 2. Suitable for continuous long-time production and steady output.  Increasing machine’s piece-rate and the quality of the products. 3. COMPACT DESIGN:  Installation area is only 600W*800D besides the forming machine.  The machine is suitable to work with any tube production lines.  Replacing oscillation tube type welders is easy as position of forming machine will not be affected. 4. Sensitive electrical parts are safely closed inside the electrical cabinet and far away from the tube welding area.  This effectively increases the machine’s life and decreases need for repair. 5. The input efficiency is greater than 0.95 for any kinds of tube size and output range.  This greatly reduces energy cost and spending on peripheral equipments. 6. EAST MAINTENANCE AND INSPECTION. 7. Dependable safety system: 　◎protection against abnormal water flow volume 　◎protection against abnormal water temperature 　◎protection against over voltage 　◎protection against over current 　◎protection against over frequency 　◎protection against low frequency 　◎protection against coil touch	COMPARISON BETWEEN SOLID STATE GENERATOR AND VACUUM TUBE GENERATORS： 1. INPUT POWER CAN BE REDUCED 40%. 2. 50% REDUCTION IN WATER CONSUMPTION 3. 50% REDUCTION IN WATER FLOOR SPACE 4. 60% REDUCTION IN WATER TOTAL MASS 5. SERVICE LIFE－ SOLID STATE GENERATOR： INFINITE VACUUM TUBE OSCILLATOR： 5,000~10,000 HOURS 6. START / STOP－ SOLID STATE GENERATOR： MOMENTARY VACUUM TUBE OSCILLATOR： PREHEAT AND COOL TIME FOR FILAMENT 7. OPERATION COST－ SOLID STATE GENERATOR： LOWER COST DUE TO HIGHER EFFICIENCY AND LESS WATER VACUUM TUBE OSCILLATOR： HIGHER COST DUE TO LOWER EFFICIENCY AND MORE WATER
