Cold iron My new Weller 100P soldering iron stopped working after only a few days. I changed the tip, cleanedthe tip, but still on heat. Any suggestions?

It is supposed to produce heat there, it's the place where catalytic combustion takes place. If the tip doesn't heat up enough, it means that either the tip is not screwed properly into the housing, or there's not enough gas pressure. The catalytic mesh should be orange in color when heated properly.
Too low gas pressure may be a result of many things, like a malfunctioning valve (regulator and/or on/off),or clogging of the ceramic pressure reductor due to poor quality gas used, with high heavy fraction content.

Hi, I'm not sure the tip is defective. Check that the tip is screwed in tight. If it is not good and tight the tip will not get a good heat transfer from the solder wand. Hope this helps. If the wand will heat then the tip should.

Also Radio shack may have the tip at a larger price, but you don't have to pay shipping

This happens quite frequently. On the tip there are two nuts that hold the tip to the gun. Tighten them a bit. The tip is made of copper and as this heats, it causes the connection where the nuts are to become a higher resistance and thus lower heat. When you tighten them, it "cuts" through the copper oxidation (caused by the heat) and lowers the resistance, hence more heat.
