HF Vacuum Tube Welder
High frequency welding pipe equipment uses the common structure of frequency conversion such as AC-AC and AC-DC. Three phase 380V-420V power supply is sent to step up transformer before it passes through switch cabinet.
High Voltage Rectifier :
It Rectifies The High Voltage Ac Power From The H.T. Transformer To The Dc Power Required For The Oscillator. 3 Phase Full Wave Rectification. Silicon Diode Mounted On Aluminium Heat Sinks Cooled By A Water Air Heat Exchanger.
Dc Over Current Relay Safety Device. High Frequency Oscillator Unit :
It Converts The High Voltage Dc Power From The Rectifier Into The High Frequency Energy And Supplies It To The Welding Point Through The Hf Output Transformer And The Output Coil (Inductor). It Is Composed Of : Pressurised All Around Access, Aluminium Cabinet Dust etc.
