Put the element out of solder and make it clean and replace it while keep in mind that element is surely connected heating filament.

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.

Soldering gun won't get hot enought to melt solder.


Take off the tip, clean the threads, and replace tightly.

Iron does not get hot enough melt solder. it used to. can I fix it?


try reshaping the tip to a dull point with a file or grinder. Then heat it up and apply solder onto the bare copper tip coating it completely. you can clean the excess off with a wet sponge. This is called "Tinning" tthe tip.

Good Luck!

I have a old modal 8200.140/100 watts. tip will get hot enough to melt the solder if you touch the tip with the solder.but will not get the wire(18 Gauge} hot enough to melt the solder.


Hello, does your soldering gun humm? If it humms then recycle the parts. There is short across the winding which causing the humm. If not, then make the you have right soldering tip for your Weller gun. Also make sure there is good tight connect on the solder tips with the barrel screws.
It could be a faulty two way trigger switch with internal diac controller. You can order switches from this web site: www.e-sonic.com/aboutus/cat/S/soldering%206.pdf GB...stewbison

I have a weller wp35, 35 watt iron. It came with the ST3 tip. I want to solder automotive wire, Say 14 to 20 gauge wire. Two questions: 1 is the wp35 strong/hot enough to do this type of soldering? 2...


The WP35 is strong enough and the ST3 tip will do the job. The larger tips are really only for covering larger items but when soldering it's the wire you heat, rather than the solder, and melt the solder with the wire. The tip will reach the same temperature regardless of the size and while the larger tip might heat the wire a little faster the difference would not even be noticeable.

My Weller PSI100K Portasol soldering gun will not get hot at the tips, but it is producing heat at the vent holes?


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.

It is not melting the solder. do you have to use flux, like sweating copper? If so, can I use the same kind of flux for this application?


No flux, just make sure the element is heating up enough.
Also make sure the tip is clean. Let it heat up and dab on a wet sponge. You can also lightly file the tip to clean off oxide build up.

If you do this last step. It is critical you Re-tin the tip.
Of course the tip must get hot enough to melt the solder.
If it still does not, I would suspect the batteries.
Good luck!
Hope this helps!

Iron is not heating up hot enough stained glass soldering iron:


hi friend,
check this out
Consider the wattage of the soldering iron. A good soldering iron will have wattage of 80 to 150. A wattage of lower than 80 is not ideal for stained glass. You need a soldering iron that will melt the solder fast enough for your project. Consider the type of temperature control you want. Some irons will have a temperature control built in the tip. When the temperature drops, it will turn on and when the temperature is reached, it will turn off. Other soldering irons have a built-in rheostat. You control the temperature by turning the dial up or down. A separate rheostat can be purchased to plug your soldiering iron into. Rheostats are highly recommended. This lets you match your temperature to your soldering style and allow you to do decorative effects.
  • Step 2 Consider the heating element. There are two types of elements, ceramic or wire-wrapped. Ceramic core irons maintain heat more efficiently than wound wire heaters. In a ceramic core, the heater core extends into the tip for faster heat transfer. This will keep the tip hot for a longer period so you can work quickly and faster. Ceramic irons maintain their temperature longer and heat up within 30 to 60 seconds.
  • Step 3 Consider the weight of the soldering iron. You want a soldering iron that is lightweight and balanced. You will have less fatigue when using a lightweight soldering iron at long stretches of time. Check to see if it fits your hand comfortably. Check to see if it has a good rubber cushion for your hand.
  • Step 4 Check for the ease of changing tips on your soldering iron. When soldering stained glass, you want to match your tip to the technique you want to use. There are a variety of tips on the market for soldering irons, and you want to be able to change them easily.
  • Step 5 Check the soldering iron to see if it has a heavy-duty cord and a three-prong plug. You want a grounded three-prong plug to prevent the possibility of shock.
  • hope this helps u

    No longer melts solder with tip....


    You have burned out residue on the tip. Clead it off with a damp cloth when the iron is hot. If this doesn't get it all, use steel wool. Immediately afterwards, get flux & solder onto the tip or it will get coated again.

    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.
