Tube Welding Machine

There are good reasons why solid state welders have displaced vacuum tube welders in the pipe and tube industry. These include higher efficiency, higher reliability, improved safety, and more installation flexibility. 

 Small harmonic interference, no pollution to the power grid

With the transformer, RC and LC filter network, the harmonic of solid state H.F welder is small.

When solid state H.F welder operates at full power, the power factor can reach 0.9 or more.

High efficiency, power saving and less cooling water

Compared with the vacuum tube welder, the solid state H.F can save 25%-30% power.

It doesn’t’ need reservoir for out water, thus, the cooling water consumption reduces by 70%.

Less welding spatter, good welding quality

The power supply waveform of solid state H.F is stable, and the steel tube weld tends to be a straight line. The tests of drawing, flattening, flaring, water pressure and other performance are qualified.
