Answers  To Your Most Common Questions

The calibration process checks the accuracy of your welding machine’s voltage and amperage. Generally, MIG/MAG, manual metal arc welding and TIG systems are calibrated. Further, if you need to ascertain if your welding equipment or system conforms to its specified operating parameters, verification is the suitable option.

According to IEC 60974−14, it depends on your welding machine manufacturer as well as you. You can have your systems and machines calibrated or verified annually or more frequently, as stated by your equipment manufacturer. As per industry standards, the ideal time for verification is post-repair, as it might impact the accuracy of values displayed by your equipment. Apart from calibration services, verification can also be helpful. It includes the processes of calibration and validation. It is always better to calibrate your machines for quality and efficient results.

The load bank applies a variable load to the power source at controlled increments throughout the power source range. Readings taken by the Fluke 179 True RMS Multimeter and the Fluke 376 FC True RMS Clamp Meter are compared to those taken from the equipment being calibrated. Adjustments and/or meter replacements are made as required until the acceptable level of calibration is met.
