Hi
If you refer ASME Sec IX, QW-253 table, which talks about the welding variables procedure specifications for SMAW, then refer QW-409.4 (electrical characteristics), which mentions that a change in current or polarity is Supplementary essential variable for Impact requirements and Non-Essential variable for Non-impact requirements.
What is your case?
