HF Vacuum Tube Welder


HF Vacuum Tube Welder

Product Details

Mains supply 415 Volts,+/-10% 3 Phase,50 Hz.
Output Current >500 A
Capacity 60 kW to 1200
Automatic Grade Automatic
Welding Type HF Welder
Power Supply AC three-phase 380V/420V, 50Hz/60z,75KVA-1500KVA

For frequency more than 200kHz or other low cost application filed, vacuum tube high frequency power supply still has an irreplaceable position and wide application. 


Vacuum tube high frequency power supply adopts AC-DC-AC frequency variable structure. Convert power frequency AC voltage to adjustable high voltage DC voltage through the matching of 3-phase AC voltage regulation circuit, step-up transformer and high voltage silicon rectifier stack (3-pulse wave or 6-pulse wave). Oscillating circuit adopts high frequency large power vacuum tube to produce self-oscillation. Resonant circuit can adopt single circuit or three-circuit mode. 


The whole unit of equipment is composed of AC voltage regulation cabinet, step-up transformer, vacuum tube (Oscillator valve) oscillator cabinet which has tank circuit, circulation water cooling system, and console.

Application Scope

  • Steel tube welding
  • High frequency quenching
