Weld Checker

Weld checkers, also known as weld current meters, are tools to help you monitor your machines’ parameters. Resistance welding production environments put a great deal of strain on equipment and weld checkers provide invaluable data to ensure they are giving the required cycle time, voltage, and weld current.

Including a weld checker/current meter in your regular maintenance routine not only ensures weld quality, but also reduces potential downtime caused by troubleshooting.

The list below contains our 3 recommended mobile meters/checkers that can be used for any application (single or 3 phase AC, DC direct (rectified) current, capacitor discharge, intermittent seam…etc). We are able to provide alternative checkers should you require them.
