I felt the booklets suggestion of 2/Max was wayy too hot cos the thin wire would burn up towards the contact tip so quickly (especially when stopping) with an unstable pool and could clog up the contact, so I moved the nozzle closer to reduce stick-out & help gas cover but it'd end up spattering all inside the nozzle.
adjusting around wire speed 7 where the speed graph begins to rise exponentially didn't help.
once I turned voltage down a notch and wire speed down to the linear range, the weld became much stabler/quieter/controllable, stick-out lengthened to a visible point without clogging the contact tip during & after welding, and spatters less.
