Brief introduction and advantages of 250KW Solid State High Frequency Compact Pipe Welder

This compact welder is the latest scientific research achievement of our company's scientific research personnel, and has obtained the national patent (ZL201520767232.X). Its main feature is to replace the original thyristor and iron core rectification with advanced high-power transistor (IGBT) and high-efficiency magnetic core transformer.

Compact welder advantages as following:

High power factor: power factor≥0.96, no need to add reactive power compensation equipment.

Harmonic pollution is small: no additional harmonic processing equipment is required

Smooth output power: small output ripple factor, less burr of welded steel pipe, more uniform weld seam and high finish

Fast protection: fault interlock protection time≤10μs. The equipment is more reliable

High power efficiency: the efficiency of the whole machine is improved because the reactive power loss is reduced

Small size, light weight, simplified wiring, convenient testing and maintenance.

Comparison of compact welder and solid-state high-frequency welder

Compact welder	Solid-state high-frequency welder
High efficiency, and electricity saving by 15%-25% than the solid state welder	Relatively high-efficiency
Single cabinet design and easy installation	Separate cabinet design, and many incoming cables between cabinets
High power factor of up to 0.96, and no need of compensation equipment	Low power factor and need of compensation equipment
Stable output stability and better welded quality	Relatively good welded quality
Full modular design and easy maintenance	Semi-modelar design and relatively complicated maintenance
