The inverter technology that allows constant and high welding current not influenced by the variation of the supply voltages and by the secondary circuit conditions, the quality of the spot is improved also on galvanized sheets. The high current value allows to reduce welding time resulting in a longer electrodes life. The reduced absorption balanced on the three phases reduces the connecting and
consumption costs. Allow simultaneous connection of two tools with automatic recall of the relevant memorized welding program, enabling to save time, avoid errors so to have a simple and safe working process.
