Good Quality Hf Welders - 500KW Series connection separated SCR Solid state high frequency welder — ERW Pipe making machine which welding steel tube straight seam – Mingshuo Detail:

The switch cabinet and rectifier are designed integrally, which not only completes the function of switch cabinet, but also has the rectifier control function of solid-state high-frequency welding machine, which is also called thyristor(SCR) welding machine

Switch Rectifying Cabinet— main parts of solid state HF Welder

●Install incoming disconnect switch,incoming current meter, voltage meter(switchable) and incoming voltage3 indicating light.

●Install 3-phase full-controllable thyristor rectifying bridge to achieve power regulation of H.F. welders.

●Install flat wave reactor,flat capacitor and filter to increase semi-wave coefficient.

Inverter Output Cabinet–main parts of solid state High Frequency Welder

  ●The inverter part is consisted of MOSFET single phase invert bridge in parallel style. Each bridge’s design power is 120kW/60kW.We adopt building block mode to pile up power,it’s very convenient to install and maintain because every bridge board is designed as drawer structure consisted of slide way.

  ●We adopt matching transformer to realize power combination,also we adopt sub-resonance capacitor(low voltage) and inductor to achieve steel pipe welding power transmission by output lead.

  ●Use sealed box and install overhead air conditioning.
