Problem with soldering gun
Doug Smith W9WI ) writes: First thing I'd suspect, especially if you're having trouble soldering PL-259s with a 230W gun, is that the tips aren't making adequate contact with the secondary of the transformer, the metal tubes coming out of the handle. At the risk of stating the obvious, those little nuts at the end of the tubes are good and tight, right? And maybe more important, the nuts can be tight but the copper is still not making good contact. Loosening the nuts and retightening is important in this case. I've not bought a tip for mine in thirty years (which means I only bought them for a couple of years). Someone gave me a yard or so of multi-strand wire left over from a TV transmitter installation, the punchline being that each strand was the diameter of the wire used for the soldering gun tips. I measured the real tip, and used it as a template to cut the wire to the needed size. It's all worked fine, and the fact that it's not plated doesn't really matter because the tips don't cost me a thing. That yard of wire is still supplying the tips. Michael VE2BVW |
