The easiest and fastest way to calibrate any type of welding machine. Just connect to the output terminals of your machine and test away!
Multiple load resistors are built into a sturdy aluminium housing, the resistors are selected using front-panel switches. Each of the 5 main switches can be operated independently and a 6-step fine adjustment switch provides more precise load settings. The result is more than 150 different load values with which all MIG/MAG, TIG & MMA power sources (GMAW, FCAW, GTAW, SMAW) up to 600A can be tested.
This wide range of load resistances allows you to test all welding processes according to the formula of the volt/amp relationship. For example, you can reach 29V for MIG/MAG at 300A, 22V for TIG, 32V for MMA and so on. Each load setting is marked with the rated current, but they all withstand high overloads, as often happens when testing welding equipment. Load resistances start at 5Ω and at all loads, the inrush resistance is 0.053Ω.
Calibrator Pro models use ‘stack effect’ cooling to attract cold air at the bottom and squeeze hot air from the top. This provides exceptional cooling of load resistors, enabling peak power outputs of over 20 kW.
Calibrator Pro instrument panels use the most accurate and stable electronics available and the accuracy exceeds the highest requirements of IEC60974-14. This enables precision-level calibration and testing where required. Suitable for the most demanding industries such as nuclear, aerospace, government laboratories, etc.
