Wondrous 1 high-voltage short-circuit testing machine

Wondrous 1 high-voltage short-circuit testing machine

Function description: A constant current is applied between the two tabs after the bridge is welded, and the voltage change is measured with a precision millivoltmeter according to the resistance between the two tabs, which can effectively detect the battery during the welding process For defects such as blowholes and false welding, the fault location is visible and intuitive. The equipment judges its welding quality by loading the current and the meter feedback resistance value. The unqualified products will be automatically alarmed by sound and light and automatically pushed out, waiting for manual processing. Thereby reducing the unqualified products caused by substandard welding.
