Solid State High Frequency Induction Tube WelderNegotiableMOQ: 1 Set
This equipment mainly used in the field of carbon steel tube & pipe welding and special section tube & pipe welding.
The whole set of this equipment consists of rectifying cabinet, inverter cabinet, central control console, step down
transformer, DC speed adjust unit and cooling system.The basic principal of solid state high frequency is that 3-phase AC current voltage is reduced by the step down transformer, and then enter into the rectifying cabinet
through the rectifying, regulating voltage and filtering and become continuously adjustable DC; then enter into
the inverter bridge(using high-power transistor MOSFET) and become high frequency current, and this high
frequency is supplied to the load tank circuit and then can be used for the induction heating. Inverter tank
circuit power unit using the modular structure, and each power unit can output above 50KW, the number of
the power unit is different according to different power equipment.The tank circuit is a kind of series and
parallel mixing form, no high voltage and no output transformer.
Equipment advantages
1.No high voltage, safety, reliability and high efficiency.
2.The main components are using foreign brands products, such as: IR, IXYS and Siemens.
3.Voltage and Current Double-fed control circuit, stable adjustment, high precision and little interference.
4.Power range 0-100% step-less adjustable, have the advantages of over-voltage,
over-current etc.fault protection system.
5.Digital display, simple operating, convenient maintenance.
6.High quality welding, uniform welding seam width, uniform temperature, less burrs in welded tube surface and
inner.

Operating Environment
This equipment is designed for indoor installation, should avoid the rain, frost and snow, sun exposure, it should also
meet the following conditions:
1.No more than 1000 meters altitude, too high altitude will reduce the air pressure result in bad cooling effect.
2. Ambient temperature -5 ℃ --- + 40 ℃, (less than 0 ℃ should prevent freeze, result in the cooling pipe
blocked and damaged).
3. Relative air humidity less than 85%.
4. No conductive dust explosion, no gas and steam can rust the metal and damage the insulation.
5. No severe vibration and shock
If does not meet the above-mentioned requirements, the customer should notified our company and we can
consider carefully in the equipment design.
