Equipped with remote programmer, can realize external remote programming settings. Five working frequencies selectable (1KHz/2KHz/3KHz/4KHz/5KHz) Six welding control modes (constant peak current, constant secondary current, constant voltage, constant power, constant pulse width, hybrid control) Quality Judgment And Control Function: Instantaneous and average values of current, voltage and power can be monitored at the same time, and pressure and displacement values can also be monitored. The upper and lower limits of the parameters can be set, and the pressure trigger and displacement depth interrupt functions are supported. Quality Traceability Function: The database can store more than 5 million welding data of welding points, and support U disk export. Welding Process Visualization: Man-machine touch interface with oscilloscope and detector functions, real-time display of current, voltage, power, resistance and other 8 real waveforms and corresponding welding data. Support multi-stage discharge, also has a slow rise and fall function Diagnostic Protection Function: With more than twenty kinds of welding fault diagnosis, welding protection module, as well as monitoring and alarm function. More suitable for the automotive industry, the whole series standard with adaptive intelligent welding function, according to the welding process of external conditions change, automatically adjust the current and time, to ensure the welding quality, to solve the problem of shunt, edge welding, non-conductive gap welding, pressure changes, plate thickness inconsistency and so on.
