70-75 amps is not too cold?I would cut the amps back a bit if only using 2.5 rods . 80 - 85 is a bit strong .. I would be down around the 70-75 mark and move a bit slower .

Woah, woah slow down there.
75A for a 3/32” might just about work, but 105A for a 1/8” 7018 vertical up, that’s just way too cold.

You could qualify a vertical down weld with no penetration if you wished.
A coding is only as good as the procedure and that’s only as good as the person who wrote it.
105 amps with enough arc force is the same as 130 amps on some other machines...
Who's to say it's too cold if it passes a code test? If it's a WPS to 15614 then you need proper penetration on the qualifying weld, and it should be a UT/rad test for the weldor to 9606 which should pick up any major flaws.
Always do my vertical up code welds using 3.2 7018 at 105 amps , so working back down to 2.5 I would say that was about right . Machine to machine there is maybe a difference in what amps say and what amps you get , but on mine that worked fine .
Yeah, my point was that even a 9606 weldor qualification requires a good solid weld to pass a UT test, and the WPS certification (15614) requires an even higher standard of weld. A pass is a pass It's the WPS you want to see though, it gives you max and min amps acceptable.Like that would satisfy ?
