Change Classification

Hi Expert,
Regard to QW404.12 stated that classification only apply for supplementary condition.That mean may be change any type as long as without CVN.
For Ex, my Wps GTAW mention classificaiton is ER 70S-G, does it change to any type as long as without CVN?

QW-404.12 fall supplementary essential.
you may change any type of electrode in the WPS with the same class, F Number, A Number, if CVN not required.

Hi Anh Biên,
Your mean is only change branch name, it’s not allow change class ?
