Look at QW 250 to 256, there you will see which QW you have to use for each process and if it is a essential, supplementary or a non-essential.
For most(if not all) heat input is a supplementary essential, which means thats its not applicable if you dont have impact test.
Yes, the procedures seem valid, if impact is not required.
However writing from 0 - 210 amps seems a little loose in regards to professional etiqette :O
IMO the WPS should be within reasonable range(+/- 25%) of the PQR, otherwise some of the points with a WPS is gone....
But according to ASME sec. IX it seem OK.
BUT remember, the manufactorer is responsible for the WPS and the welds done in production.
