Essential variable for welder qualification or procedure qualification?
For welder qualification, it is an essential variable if the electrode does not have an F number.
For procedure qualification, it is only an supplementary (impact testing required) essential variable if the electrode has a general (or -G) classification, such as E9018-G.
These do not usually apply for run-of-the mill welding though. If you only run electrodes with standard AWS classifications, it is not an essential variable.
