SOURCE: my Weller PSI100K Portasol soldering gun will not

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.

Do stained glass soldering tips go bad or stop working. I have a weller soldering iron that doesn't heat up hot enough to solder. is it the tip or the iron


If this is the dual trigger Weller gun and your tips are held in place by either set screws or by locking nuts, Just loosen both of the parts that are holding the tip to the gun and then retighten them back up. Soldering iron tips that appear to be tight might not be and this will insure that the tip is indeed tight and also cleans up the connection of the tip to the soldering iron. Oxidation from heating and cooling will cause a tip to not get very hot. Loosen the tip holder and then retighten it. Hope this gets you going again.

It will not heat up, maybe tip needs to be cleaned, if so how? I lost the manual. Thank you..


I am assuming that you installed a new tip. Note, the tip ends have to be 3/8 of an inch 90 degree bend so that when you insert the tip leads into the barrels, they go into the small holes in the barrels. Also note, the nuts to tighten the tip into the gun have to be installed onto the tip leads before bending the leads. Now when the tip is installed this way, the nuts tighten and hold the tip in the barrel. This tightening of the nuts allow the tip to have a good electrical connection to the barrels and this is what allows the tip to heat. You actually have an electrical current that passes through the barrels and the tip. It is a very low voltage (around 2) but a very high current. Over time the tip will not heat, this is a sign to either tighten the nuts, or look at the tip to see if it has a break in it. If it has an open, then it is time to change the tip.

The tip of my weller 200D soldering iron was replaced about a month ago. I have just plugged it in to use it and it is not getting hot anymore.


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.

How do i use this product(Weller model Standard 7200)?


You need the nuts that hold the tip in the iron--slide them on, then bend the ends sideways with pliers and leave about 1/4" sticking out sideways. Be sure to make the upper and lower bends in the same direction. Be sure to tin the new tip with solder when you first heat the tip. Hope this helps!

Intermittent heat on Weller D550 although lights stay on. When not working, moving the terminals may get it to start working again. Sometimes, just moving the gun will interrupt the heat. Continuity...


Heat gun tips often get bad electrical connection where the nuts tighten to the tip ends. Remove the tip, clean the ends, re-install the tip, making sure the nuts TIGHTEN onto the tip ends. Your problem is common and always caused by a poor connection at the tip ends/nuts.
