ZX7-400 (Z245)
1, the use of advanced IGBT inverter technology, hard switch control, frequency of 20KHz
2, small volume, light weight, temporary load rate is high, 60%.
3, with preset, the actual table display function, more direct and convenient operation.
4, wide power supply design 380V 15%.
5, with thrust, heat guide arc adjustment, to meet the needs of all kinds of welding process.
6, no-load voltage is high, easy to lead arc, splash small, current stability, forming good.
7, Holzer feedback, output stability, precision.
8, the new design more in line with human nature
