I use a 325 watt gun with a BIG tip. I also have an 80 watt iron used for making stained glass window panels but I usually use the big gun since I know where it is and it heats faster. This reminds me that I need to get more tips for it.
Lowe's sells the 80 watt stained glass model with the other soldering stuff. The tip that comes with it is excellent for PL-259s.
Remember, it takes longer to warm up AND to cool down.
My bad. LOL I meant that I need to get more tips for the large gun. My brain was thinking one thing while my fingers were typing something else. You are correct however in that the 80 watt iron tip is indeed great for soldering PL-259's.
