We offer Tube Welders:- NSSW Solid induction HF Welding Unit (HF Welder) Suitable for continuous production of Longitudinal Welded tube and pipe production lines. Components of the Equipment : NSSW-Solid State Induction HF Welder composing ofSCR DC Powersupply, HF inverter and water cooling unit(air-water-or water heat exchanger) Major Parameters : Power Supply AC three-phase 380V/420V, 50Hz/60z,75KVA-1500KVA (Different input voltage and frequency can also be arranged) Oscillator Frequency : 200 KHz-400KHz Output Power : 50 KW-1000KW Cooling Method : Water Cooling Major Specification : 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. The component have been used for the control systems were produced by world known manufacturers. The parameters of voltage, current, power and frequency have shown diagnostic capabilities. The seams welded with higher qualities due to the use of multi stage filtering system.
