The 4645T is an air-operated, high-speed, spot-welding machine of the rocker arm type. It is equipped with a built-in, programmable welding timer of the TE 101 type.
240kVA MFDC
Traditional resistance welders use a single-phase transformer that supplies alternating current, the welding current is regulated by thyristors using phase shift technology. This new technology uses an inverter powered by three-phase power. Inside the inverter, the current is rectified, filtered by capacitors and transformed by an IGBT bridge into alternating current at medium frequency (1000Hz). A specific transformer equipped with a rectifier that supplies rectified welding current is used.
