Solid State High Frequency Welder is also called ERW Welding Machine, Solid State High Frequency Welder for carbon steel, aluminum copper, stainless steel tube & pipe welding featured with high efficiency and reliable. Solid state high frequency welder is an important part of the steel pipe production line, It is specially designed for straight seam welding. Solid State High Frequency Welder consists of Switchgear Rectifying Cabinet, Inverter Output Cabinet, Optical fiber, Water-water cooler and Console.
· Solid State High Frequency Welder
Solid State High Frequency Welder features: Simple circuit and flexible installation, Complete protection and easy maintenance, Small harmonic interference, no pollution to the power grid , High efficiency, power saving and less cooling water, Less welding spatter, good welding quality, Load matching technology (optional).
Solid State Welder Machine Inverter Unit
The Solid State Welder inverter part is made up by parallel MOSFET power transistor modules, which is easy for maintainance.
Stable DC output — enhanced by 3-phase full-controllable thyristor rectifying bridge, flight wave reactor, filter capacitor, and filter reactor.
Independent current & voltage display and control system — the welder is controllable even without central control unit.
Compact, sealed and internally water cooled cabinet.
DC Power Unit
DC Power Unit includes rectify, flight wave and control parts:
Independent current & voltage display and control system — the welder is controllable even without central control unit.
Low Ripple Fiter — Reduces AC line harmonics and DC Ripple, ensure the weld quality.
Central Control Unit
Installed with LCD, power and speed adjust module, the pipe line can be completely controlled by the central control unit.
Water-water Heat Exchange Unit
Composition：Plate heat exchanger, water tank, pump and electrical control part.
Closed loop circulation, outer water (normal) cools down the inner water (distilled water), no scaling.
