Dear All,

Can any one help me!

PQR Qualified with an amperage of min 350 and max 550.
As per AWS D1.1, Allowable Variation in Amperage for WPS  is 10 %.
How should i consider this 10%.

Case 1
Should i Consider lesser 10 % lesser to  PQR's Min Amperage and
Greater side 10 % to the max PQR Amperage.

Case 2
Or Should i consider 10% min max of Average of PQR Value.

Which case is correct?
