Brief Introduction of Solid State HF Welder

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.

Technical Advantages:

1. Varactor Technology of induction welding ensures wide load matching range.

2.  Self-developed unique control structures of the circuit design leading to stable equipment operation.

3.  DC Power supply with constant power output has a soft-start function to prevent the impact of the circuit.

4.  Central control unit achieves centralized display and easy device operation.

5.  Equipment cooling system adopts plate heat exchangers. Small footprint, long life and easy maintenance.

Features:

1.Simple circuit and flexible installation

2.Complete protection and easy maintenance

3.Small harmonic interference, no pollution to the power grid

4.High efficiency, power saving and less cooling water

5.Less welding spatter, good welding quality

Supply list

Detail Instruction for each Unit:

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.

INVERT 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.

CENTRAL CONTROL

Installed with LCD, power and speed adjust module, the pipe line can be completely controlled by the central control unit.

Dispay and alarm — the output current and voltage of the DC power unit; armature voltage and current, excitation voltage and current of the DC speed adjust unit. 

WATER WATER HEAT EXCHANGE UNIT

Composition：Plate heat exchanger, water tank, pump and electrical control part.

Closed loop circulation, outer water (normal) cools down the inner water (distilled water), no scaling.

Heat exchanger fins — High efficiency of heat radiation, low cost, applicable to large power H.F equipment.

Stainless steel water pump and copper pipe — less polution of the loop.

Stainless steel water tank with level switch — easy to check water level.

RECTIFIER ISOLATION TRNSFORMER

It is the input rectifier part of the equipment. It reduces the input voltage from 415V to 200V to ensure stable power supply, at the same time, to insulate the power grid.
