We take pleasure in an extremely fantastic standing among the our prospects for our great product top quality, competitive cost and the finest support for Solid State Welder Auxiliary Equipment Manufacturers, Steel Tube Making Factory, Series Solid State H.F. Welder High Frequency Induction, We are confident that there will be a promising future and we hope we can have long term cooperation with customers from all over the world.
Good quality Hf Welding Machine For Erw Pipe - 1000KW large diameter tube production line–Series connection type Solid state high frequency welder – Mingshuo Detail:

The switch cabinet and rectifier are designed integrally, which not only completes the function of switch cabinet, but also has the rectifier control function of solid-state high-frequency welding machine, which is also called thyristor(SCR) welding machine;

There is no need to add a step-up/step-down rectifier transformer at the input end of a solid-state high-frequency welding machine. Compared with an vacuum tube welding machine or a parallel solid-state high-frequency welding machine, it has a more obvious energy-saving effect (compared to an electronic tube welding machine, at the same level). Under welding conditions, power saving ≥30%).

 All-digital control system

1.3-D rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.
2. 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.
3.The welder has electronic automatic load matching function with good load adaptability, high electrical efficiency and high power coefficient.
4.The welder has perfect protection function with reliable working and low failure rate.

Conventional design. can be customized according to user’s grid, technics requirement and working frequency.

The welding speed is based on the condition of max O.D. and max wall thickness.

General design, can be designed as per user’s technics.
