Product Description

Solid State H.F Welding Machine
Perfect structure design
Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at user’s site.
The rectifier adopts 3-phase 6-pulse thyristor rectifying. For large power welder, 12-pulse thyristor rectifying can be selected to eliminate grid side fifth and seventh harmonic, and grid side harmonic current is the lowest.
Power combination of the inverter bridge is accomplished by the way of power unit superposition. Each MOSFET power unit is designed to be 50kW/100kW/150kW and slideway drawer structure, which is convenient for installation and repair.
High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.
Closed cabinet design, meeting rigor environmental requirements on site.

* The user needs to prepare three winding power transformer.

H F Welding Machine

Full digital control system
3-D rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.
Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.
The welder has electronic automatic load matching function with good load adaptability, high electrical efficiency and high power coefficient.
The welder has perfect protection function with reliable working and low failure rate.

HMI and fault diagnosis system
Adopt PLC and touch screen to form perfect HMI system.
Realize integrated automatic control of welder system.
Fault display and diagnosis system.
