PMC-53A Weld Checker (desk-top type)
Highly functional and highly precise weld monitor & weld checker for various weld current waveforms.
Cyclical and accurate display of the welding time for AC inverter welding.
Light and compact body. Fast measuring speed, and easy installation.
Simple “turn” and “press” operations with a single button.
The measuring unit from “ms” or “Cycle” on measuring welding time can be selected.
Communication facility is equipped on standard.
Measured values can be transferred to a PC and the evaluation criteria can be changed from the PC. RS232C and RS-485 are equipped on standard
