MM-123A Weld Checker

The MM-123A is the very latest in stand-alone weld checker technology. This multi-functional weld checker comes in small, compact design.

The MM-123A now features voltage monitoring. This allows you to monitor important variable for quality control.

The MM-122A uses a Toroidal coil for sensing. The correct coil needs to be matched to your application – MB-400M/MB-800M.
