Follow the link and you will find a data sheet that contains parameters for your self shielded FCAW wires. Just scroll down till you see Innershield NR-232

Remember  Straight polarity

And recommended stickout varies by diameters of the wire so check close.

The data sheets may give a range of amperages and voltages for a given diameter.  Best to start at the lower range (more think time) until you get a bit of practice than you can increase to get more productivity once you begin reading the puddle better.

You will want to use CV.

NR 232 has a very heavy slag and really welds nothing like NR 211 which has an extremely light slag.  232 welds really well on groove welds, or anywhere alot of metal needs to be deposited.

Keep the puddle hot and the bead reasonably narrow, maybe 5/8" or so max - do not use a 7018 / E71T-11 type weave.

For arc length, I like to start with the voltage low enough for the slag to flood the arc and then add voltage slowly until it clears up.

Generally, I tend to drag except for vertical cover passes (when I push) and when overhead (when I tend to go straight in)... but there are always exceptions.
