Glad you took it with a smile!
It welds just like any other low hydrogen electrode. No whipping, slight weave is fine. I hope they provide a WPS listing the preheat and the maximum interpass temperatures. Don't be afraid to weld hot (on amperage that is). I would probably look at somewhere around 130A, keep a short arc length. Again, if you're comfortable with 7017, this will be no different.
They could have you weld on a plain carbon steel or a Q&T HSLA steel. Either way, the filler metal is usually used on Q&T HSLA steels, so keep in mind you have to maintain a minimum preheat and interpass, but as the temperature approaches the listed maximum interpass temperature, stop and allow the assembly to cool until the temperature is well below the maximum. This is intended to minimize the size of the HAZ, grain coarsening, and poor toughness.
