In the field of industrial welding, transformers are the core components of power conversion, and their performance directly determines the welding accuracy and efficiency. Huandian Transformer has developed five major product series adapted to different working conditions through differentiated technical paths, covering the full-scenario needs from traditional arc welding to intelligent robot welding.
DC Welding Transformer: High-Frequency Precision Control
Using high-frequency chopping and core coupling technology, DC power is converted into high-frequency AC output, and the current fluctuation can be controlled within ±1.5%. This technology solves the pain point of poor arc stability of traditional AC welding machines, and is particularly suitable for welding precision parts of aerospace. Through the adaptive impedance matching algorithm, the impact of load mutations on the equipment is further reduced.
AC Transformer: Power Frequency Reliability Design
The power frequency solution based on the principle of electromagnetic induction adopts a laminated core of silicon steel sheets and a high-temperature resistant enameled wire structure, and the no-load loss is reduced by 30% compared with the industry standard. In continuous operation scenarios such as automobile chassis welding, 8,000 hours of trouble-free operation can be achieved.
High-current welding machine transformer: hybrid heat dissipation breakthrough
For the welding needs of thick plates such as ship keels and pressure vessels, the innovative dual-winding parallel topology design has an output current of up to 8000A. Combined with forced air cooling and water cooling circulation systems, the continuous working temperature rise is ≤60K, breaking through the heat dissipation bottleneck of traditional transformers.
Single-phase welding transformer: mobile scene adaptation
Adopting nanocrystalline alloy core and compact structure, the volume is 40% smaller than the traditional E-type core. The input voltage is compatible with 220V±15% fluctuations, making welding transformer the preferred equipment for outdoor engineering maintenance and emergency welding.
Medium-frequency inverter resistance welding transformer: high-frequency upgrade
Integrated IGBT module and digital control technology, the operating frequency is increased to 2-20kHz, and the welding cycle is shortened to 10ms. In the spot welding of new energy vehicle battery modules, millisecond response and 60% energy consumption reduction are achieved, promoting the transformation of welding technology to intelligentization.
Through multi-dimensional technological innovation, Huandian has increased the energy efficiency of transformers to more than 96%, and built a full life cycle management system from material selection to heat dissipation design. In the future, the combination of IoT monitoring and predictive maintenance technology will further expand welding machine transformer's application boundaries in smart factories.
