The
MM-122A is the very latest in stand-alone weld checker technology. This
full function, cost effective unit is designed to monitor every type of
welding control. The unit’s “miniature” design allows it to be mounted
in any position on the welding machine. Limits for Peak or RMS current
provide vital weld quality indicators. Multiple schedules, error
signaling and versatile I/O make this unit as valuable for bench
systems as it is for automated welding systems. Printer options or
RS-232/485 provide for data collection and weld process analysis,
critical in today’s advanced manufacturing processes.
The MM-122A uses a Toroidal coil for sensing. The correct coil needs to be matched to your application.
