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.

Is there a manual for this tool - I just got it but it did not have a manual and I have never used a sodering gun before. Or is there a good website with instructions. Thanks


There are several websites that teach you how to use the tool including tips. you can go to weller .com the most important tip is once its plugged in and depending on the soldering gun. some are activated by a trigger and some are not, handle the tip with care because it gets extremely hot and can cause injury if one is not careful. if the tip is hot keep it away from anything that can ignite or flammable materials. its a good tool for making permanant wire splices, used in conjunction with tinned solder and flux. not recommended for doing pc board repair because of the extreme head produced. can also be used to shrink tubing around wire splices. good luck!

Wont heat enough to solder


Hello, does your solder iron --Weller- humming? Also, is the solder tips the right tips for you Weller woldering gun? Are the tips tightened on the end of the solder gun prongs?

Well, if it is humming there is internal short in the windings inside of the gun. Don't mess with. Recyle it by taking the copper, brass, aluminum, and other metal out. Now, if it is not humming.
Make sure you have right tips, make sure that the tip is tightened in the soldering gun prongs.

The working principal of these soldering guns is that they work on low voltage and very high current. The current is regulated to keep the tip from burning into. Just enough current to heat the tipe to a certain temperature.. It can shock you but there not enough voltage with current but it will hurt. and could burn you. Be careful and lots of luck...GB...stewbison

Does not melt solder


The body contains a transformer, which steps your 120AC down to a lower voltage. The lower voltage runs THROUGH the tip, heating it up. Possibility ONE: Transformer is no good, throw it away. TWO: Not enough current is running through tip, because tip is corroded OR those mounting nuts are corroded, loose, OR somebody put new tip into nuts but neglected to bend both legs of new tip 90 degrees. Look at the barrels, you will see little holes in the sides, tip's legs go into those holes.

MY WELLER SOLDERING GUN IS GETTING HOT AND A LITTLE SMOKE COMES OUT NOW AND AGAIN IS THERE ANYONE IN SOUTH AUSTRALIA WHO CAN FIX IT FOR ME AS WELLER SAY THEY DONT DO ANY REPAIRS ON THEM. CHRIS


these are not worth repairing as the main part of a soldering iron is the transformer which is what causes the tip to get so hot, so if yours is giving off smoke and excessive heat probably the transformer is starting to cook itself which means it has to be replaced. I would guess that the transformer will cost you more then a replacement soldering gun on ebay would cost. Hope This Helps Don

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.

Soldering gun Question


Where soldering irons have a heating element that heats a copper or alloy tip; in a soldering gun, the tip is also the heating element. Most soldering guns are hot enough to solder in less than 5 seconds and cool enough to touch in less than a minute. Soldering guns are ideal for the typical home electrical job like connecting speakers or installing automotive accessories. These jobs often have only a few connections to solder so a soldering gun can be a real time saver.
