Weld monitor

Portable weld current meter

WCM 300

The WCM300 weld current meter is used to measure the current in resistance and capacitor discharge welding.

It is suitable for measuring on standard alternate current machines (AC), direct current (three-phase rectified or medium frequency) machines (DC) and capacitor discharge machines (CD).

The WCM300 displays the main process parameters rms value and duration of the weld current as well as the thyristors ON time (in electrical degrees).

This greatly simplifies the troubleshooting and setup of the welders on the shop floor.
