Weld Checker

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
