High Frequency Tube Welder uses the common structure of frequency conversion such as AC-AC and AC-DC. The Tube Welder rectifies the high voltage AC power from the H.T. Transformer to the DC power required for the oscillator. The Tube Welder is composed of pressurized all around access, aluminium cabinet dust etc. The High Frequency Tube Welder is designed in such a way that it ensures long lasting service.
