^^^^^^^^^^^^^^^^
The copper wireguide protrudes through the nozzle, so removing the nozzle
should have no effect, except:

You will be working in crowded conditions, where, as you say, it may be
difficult to see. Be extra careful not to let the copper end touch
anything. I can't remember for sure, but I think I've done this.

BTW, since you say you're not used to using fluxcore--be sure to reverse the
polarity on your torch.
