QGT-1 series solid state H.F welder is specially designed for straight seam welding. It adopts high power components of US IR IRFP460 MOSFET and Germany IXYS Company DSEI60-06A rapid recovery diode. The high power capacitor C and inductor coil L compose current-mode parallel upper-voltage resonance circuit, which doesn't need output transformer. Thus, it not only improves the efficiency, but also increases the reliability of the welder.

The solid state H.F welder has such distinct features as energy-saving, effective welding, simple structure, easy maintenance, low failure rate, low maintenance cost etc.

Working principle of QGT-1 series solid state H.F welder:

                                            Circuit Type Inverter (Composite Resonance)

Introduction to Equipment Composition and Functions

1.DC Power Unit

DC Power Unit includes rectify, flight wave and control parts.

Independent current & voltage display and control system - the welder is controllable even without central control unit.

Low Ripple Fiter - Reduces AC line harmonics and DC Ripple, ensure the weld quality.

SCR Power Supply - Provides constant output power for consistent weld quality.

Rectifier Circuit - 6 pulse Retification.

Simens PLC - easy to control and diagnose.

2.Inverter Output Unit

The inverter part is made up by parallel MOSFET power transistor modules, which is easy for maintainance.

Stable DC output - enhanced by 3-phase full-controllable thyristor rectifying bridge, flight wave reactor, filter capacitor, and filter reactor.

Independent current & voltage display and control system - the welder is controllable even without central control unit.

Compact, sealed and internally water cooled cabinet.

Automatic load matching system - enables the welder to run at optimum efficiency with +/- 1% frequency stability.
