Product Description
Professional Supplier 330KVA Direct Current Welding Machine
Welder technical parameter
Cotroller introduction:
1) Output frequency of the inverter power is 1000HZ;
2) With automatic correcting system for welding current.
3) Support total Max 64 welding programs, which can be selected form internal or external.
4) It supports proportional valve function: The output voltage is 0-10V. With automatic pressure
calibrating function and pressure can be programmed . With the proportional valve,it can achieve stepper pressure, saddle pressure. It supports two kinds of pressure setting modes, one is percentage mode and the other is KN mode (this function is optional).
5) The welding time for each current pulse is 0 ms to 2000ms;
6) Automatic Repeat Welding Function. When the real time welding current is lower than the lowest-set value,the welder wautomatic execute the repeat welding and the repeat welding times can also be set by user.
7) Counter for Welds. This welder can count the number of welding spots for each part, each shift production, total production, and total welds. It can monitor the missing welds or more welds.
8)Welding parameter can be copied. The welding programs can be input and output by the flash drive. And through thepanel ,the welding programs can be uploaded and downloaded between different machines.
