It adopts imported German IGBT modules and Japanese metal film capacitors. The inverter frequency reaches 1000Hz. The installation base integrates an efficient water-cooling heat dissipation circuit. The connection busbar is made with high-quality oxygen-free copper, effectively reducing the heat loss caused by power conduction.

It is made by stacking ultra-thin high-permeability silicon steel sheets. The secondary output terminal uses a copper conductive block to reduce current transmission loss. The transformer is equipped with a built-in circulating water cooling channel, which cools the primary coil and secondary coil respectively, avoiding excessive temperature during continuous welding and prolonging the service life of the transformer.

The equipment is equipped with an industrial computer. The database collects and stores real-time welding parameters of the wheel rim (including current curve, pressure changes, and welding time) in real time. The data storage period is ≥ 1 year, supporting later data traceability to ensure welding quality.
