When I was learning the EC trade in the dinosaur ages, my lead Journeyman insisted on soldering all ceiling fixture connections before installing wire nuts. It took a lot of extra time and frequently meant solder splashes on the floor or worse yet on the sock of my foot but I went on later to continue that practice, before I decided to persue other career paths in my life. I still have the old original Weller 550 watt soldering gun that still works, but is a bit dusty now.
35 years later, and perhaps starting up as an independent EC again, is this still a practice which one could follow as a returning EC?
There is nothing in the code that precludes you from doing this...
Pay attention to...
1) The mechaical state of the joint before you solder it.
2) The insulating rating of whatever tape you use to insulate the soldered joint afterwards.
3) The type of solder and flux needs to be non-reactive with copper.
Take a look at 12-112(1) & (2) and 2-114.
Having said all this... I would wonder why you would want to heat up that old Weller. I do have to admit I have my own old Weller kicking around as well as an old solder pot my father used when he was an apprentice back in the early 50s, but... I consider this stuff to be more museum exhibits then active tools.

I'm relatively new to the trade (5yrs) and I have found that different brands of marrettes make the difference. I ONLY use the blue IDEAL marrettes (the can-twist) because they catch and make a solid connection every time. If ya still want to solder it, buy a butane torch...those gun type soldering irons are garbage!
