Product details

• Solid State H.F Welding Machine
• Perfect structure design

l  Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at user’s site.
l  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.
l  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.
l  High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.
l  Closed cabinet design, meeting rigor environmental requirements on site.
* The user needs to prepare three winding power transformer.


• Full digital control system

l  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.
l  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.
l  The welder has electronic automatic load matching function with good load adaptability, high electrical efficiency and high power coefficient.
l  The welder has perfect protection function with reliable working and low failure rate.


• HMI and fault diagnosis system

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