Looks like it comes with the standard array of nozzels. I use the equivalent of the 6mm diameter one for all my SMD work, never bother changing it.
With the soldering iron tips, since it's obviously a Hakko knock-off, it hopefully fits the good quality Hakko tips.
For most work, I use the
K tip, Hakko part number 900M-T-K
It suits a wide variety of work as you can use the tip from different angles depending on the heat conduction area you need. For example, use the wide side of the tip for soldering a heavy power cable, or use the pointy tip for small SMD stuff. I've been using these tips on nearly a daily basis for the last 15 years after a recommendation from a Hakko sales rep.
For very fine pitch stuff, I use the
1mm needle tip, Hakko part number 900M-T-1C
I think they also do a 0.5mm tip, but unless you're working on SMD stuff smaller than 0402, it's probably not much use.
Fine tips are not good for many jobs as you can't get heat conduction to the end of the tip fast enough for anything with much thermal mass. So you have no hope of using desoldering wick with it for example.
Hope that helps.
