tweak232 Posted December 29, 2004 Report Share Posted December 29, 2004 I just got a new iron and heated it up, but didn't tin the tip immedietly and now it won't heat the soder, except places that don't look oxidized. What should I do, just sandpaper it, and what should I do to keep my tip in good condition? Quote Link to comment Share on other sites More sharing options...
audioguru Posted December 29, 2004 Report Share Posted December 29, 2004 Hi Tweak,I have used temperature-controlled soldering irons for most of my long life. They heatup to operating temperature very quickly, don't cause overheating damage to components, heat more at full power to solder something that is big, and allow the tips to last almost forever. No oxidization. The rosin in the solder doesn't turn to charcoal and therefore does its "wetting" job properly.Try one and you won't use the old "too hot" kind anymore.All you can do for your oxidized tip is to sand it gently (it might have a thin layer of plating under the oxidization) and tin it immediately.

tweak232 Posted December 29, 2004 Author Report Share Posted December 29, 2004 Ok, I did that and now it is working fine. thx Quote Link to comment Share on other sites More sharing options...
EnigmaOne Posted January 10, 2005 Report Share Posted January 10, 2005 We used to use a chemical--that I cannot, for the life of me, remember the name of now--to clean off oxide residue from soldering irons, before they started cladding the tips. It worked well on the clad iron tips as well, IIRC.I can say that I've seen Radio Shack # 64-020, and another item:from here: http://www.dt.com.au/category.php?pagefrom=ELECT:TOOLS&cat=ELECT:TOOLS:SAIDSthat you might find helpful for problems like this in the future.

Codyhtml Posted February 25, 2005 Report Share Posted February 25, 2005 i have a problem kind of likr this woth my cold heat soddering gun i get it to heat but the sodder won't melt even if the tip is directly on the sodder anybody know much about cold heat Quote Link to comment Share on other sites More sharing options...
MP Posted February 27, 2005 Report Share Posted February 27, 2005 Time to replace the battery.MP Quote Link to comment Share on other sites More sharing options...
Codyhtml Posted February 28, 2005 Report Share Posted February 28, 2005 i've replaced the battery but it still dosent work verry good i'll try again thanks Quote Link to comment Share on other sites More sharing options...
MP Posted March 1, 2005 Report Share Posted March 1, 2005 The tip is actually causing a short circuit which acts somewhat like a welder. It creates heat from this action and that is what causes the solder to melt. This is why I suggested a battery change. It does not take much to zap a C cell. The other thing I would look for is a dirty tip or possibly a crack or chip in the tip. This would cause a problem. A dirty tip would reduce current flow and then the solder would not melt. In this case, you might still get enough current to get the board hot.MP Quote Link to comment Share on other sites More sharing options...
