Weld Checker


Analyzers portable for welder machines and equipment’s calibration

ISOTRON developed a weld checker line to help the professional’s resistance welding sector. The equipment can be used on welding machines of low frequency, mid frequency and capacitive discharge. With the WELD CHECKER the user can periodically inspect welding machines, helping for process report and follow equipment maintenance.


The friendly user interface associated with the touch screen provides greater interactivity and easier interpretation of monitored data and the available functions. The main features stand out the visualization of the monitored current waveform in function to the time. This features associated to low cost are the main differentials of IWC-107 weld checker in relation to the competitors.
