Solid-state HF Tube Welders have replaced welders employing thermionic valves (vacuum tubes), thus improving the efficiency by nearly 40% and eliminating periodic expenses on replacement of valves. Solid-state welders have better up-time and are also more compact, compared to valve-type welders.
HF welders manufactured by GH India employ current-fed inverters using advanced transistor technology. They are well protected against short-circuit, open coil, arc-over, and grounding with the tube.
The electronic control circuits of the welder are robust and have excellent immunity from electrical noise.
GH HF welders employ 12-pulse rectifiers to minimise the ripples in the weld current, thus assuring excellent weld quality and uniform seam.
GH India also supply automatic control of weld power, based on mill-speed, with options of computer- or microprocessor-based systems.
