TENYES Inside Dry Transformer Solid State High Frequency Welder is made in China. Our company have rich experience in manufacturing high frequency induction heating equipment. Our products have oblivious advantages in price and quality. Most of our Inside Dry Transformer Solid State High Frequency Welder export to Southeast Asia, Middle East countries, African countries, West Asia,South America, Russia markets. We always try to find agents from all over the world to sale our welder.
This TENYES Inside Dry Transformer Solid State High Frequency Welder is specially designed for straight seam pipe 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.
This TENYES SCR Inside Dry Transformer Solid State High Frequency Welder is the most stable pipe welder, and this welder with a 1-year warranty. The TENYES SCR Inside Dry Transformer Solid State High Frequency Welder is mainly consist of rectifying cabinet, inverter cabinet (including air conditioner), console, cooling system and step-down transformer. We adopts tradition SCR rectifying technology. We can manufacture SCR Inside Dry Transformer Solid State High Frequency Welder from 50KW to 1200KW.

Welder Scope of application of SCR Inside Dry Transformer Solid State High Frequency Welder:
It is mainly used for welding various types of longitudinal steel pipes such as low carbon steel, high-strength steel, alloy steel, etc.
1. No high voltage, safe, reliable and efficient.
2. The main components are international famous brand products, such as: IR, IXYS and Siemens, etc.
3. Voltage and current double feedback control circuit, stable regulation, high precision, small interference.
4. The power range is stepless adjustable from 0-100%, with over-voltage, over-current and other fault protection systems.
5. The working status display is digital, the operation is simple, and the maintenance is convenient.
6. The welding quality is good, and the width and heat of the weld are uniform.
The basic principle of SCR Inside Dry Transformer Solid State High Frequency Welder: after the ordinary three-phase alternating current is stepped-down by the transformer, it enters the rectifier cabinet and becomes continuously adjustable direct current after the rectification, voltage regulation and filtering links; It then enters the inverter bridge (the main power component uses a high-power transistor MOSFET) and changes to a high-frequency current, which can be used for induction heating by supplying the load trough. The inverter trough power unit adopts a modular structure, each pair of power units can output more than 50KW, and the number of power units used is different depending on the power of the equipment. The trough is in the form of series-parallel mixed resonance, there is no high voltage, and there is no output transformer.
