High Speed Current (HSC) – reliable projection welding on high-strength steels

When welding nuts on high-strength, hot-formed sheet metal (such as 22MnB5), a rapid current rise is required to achieve a good connection of the nut. With the High Speed Current (HSC) option, an optimized control of the inverter control circuit has been achieved, which enables the user to achieve a faster current rise in a very short welding time (<20ms). Together with a low-resistance secondary circuit of the welding machine and low inductance of the welding window, HSC achieves very fast process dynamics that are comparable to KE welding processes.

Designed as an integrated component of the XPegasus operating software, the HSC mode can be used alongside the classic current-controlled mode (KSR). With a secondary voltage of 13V to 21V, typical welding currents of 60-80kA with current rise times of 4-10ms can be achieved in practice.

The High Speed Current option is available for the GeniusHWI range of MF inverters in all power classes.
