High Frequency Solid State Tube Welder with Solid state high frequency welding pipe equipment's Solid state high frequency welding pipe equipment uses the common structure of frequency conversion such as AC-DC-AC. Three phase 380V power supply is sent to step down transformer before it passes through switch cabinet. The AC power supply is around 200V which has been dropped voltage to sent into the rectifier in rectifier cabinet, Rectifier use three phase thyristor fully controlled bridge rectifier, through control thyristor break over time delay angle a to achieve the purpose for adjustment output power size

• Water Cooled Larger power MOSFET has been used to for modularized structure. Solid state transistor is used.
• Larger capacitors bank C and the induction coil L mounted surrounding the welding tube directly outputs coupling resonant without adapting any matching output transformer.
• That enables the welder achieving higher output efficiency. The electric energy can be saved up to 30%.
• The Unit adapts compound resonant without higher voltages resulting safe and stable operation of the unit
