There are welding codes, such as AWS D1.5 Bridge Welding Code, that do require the calibration of the meters, i.e., typically voltage and amperage.
Oct 01, 2009· This is a real thorny issue with some of our orbital tube welding equipment. As little as 1-2% change in amps can make or break some of our weld procedures. With different manufacturers having different calibration methods, the machines are not always calibrated apples to apples.
I am the Quality Engineer for a Welding/Fab shop (12 welders-mainly GMAW & FCAW process). I have established our ISO-9000 system which requires the "calibration" of our welding machines.

Mar 25, 2015· We can see from the plate its a 40-450 amp machine with a welding voltage of 16-36.5 volts. OCV is 17 to 48. Now, this is the important bit as far as the test is concerned, for a Standard Grade calibration on a set with digital meters the tolerance is 2.5 percent of maximum no load voltage. And 2.5 percent of maximum rated amperage. Ie.
