Overview

The on-site calibrator for welding machines (hereinafter referred to as the "calibrator") is a measuring standard instrument used to calibrate the no-load voltage, welding current, and load voltage of DC welding machines. It complies with JJF1085-2022 "Calibration Specification for DC Welding Machine Power Supply". The calibration device has the technical characteristics of small size, easy portability, high accuracy level, easy operation, and high safety factor. At the same time, it can calibrate the DC current output values of battery charging and discharging testers, high current generators, etc. on site. The calibrator and load can be combined according to user requirements, and wheels can be added for easy movement.
