Your welds don’t show any gas coverage issues so I wouldn’t worry about it. If you turn down the current when shortening the stick out then you will be mitigating the effect of shortening the arc. You need to increase the wire speed a bit with a longer stickout to keep the weld in short circuit transfer, with a long stickout the weld will want to go into gobular which will be harder to control and create much more spatter. Just give it a go, get your settings right for a standard run and then shorten the arc and lengthen it. You will see what I mean, gobular transfer sounds like cracking / popping whereas SCT (dip) sound like sizzling.
