Not getting hot enough

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

First you will need a pin out of the adapter.
Tools you will need are.
1: Solder with rosin core thin solder would be best 2: Soldering iron lower watts the better 3: Flux to clean the surface you want to solder to 4: Sponge to clean the tip of solder iron If you don't have any of thous supply's it would be cheaper to buy a new cord. Also if you don't have vary much experience soldering i would also recommend getting a new cord for the fact you can cause more damage than good.

To get the solder iron ready you need to heat it up. Once it is hot enough to melt the solder apply the solder to the tip and let is set there until you want to solder. You have to clean the tip off with a wet sponge but not soaked in water just enough to get it wet. Every time you go to solder Clean the tip off and apply fresh solder to it not a lot just enough to cover the tip when you want to solder. When you go to store the iron apply a small blob of solder to the tip to keep it from oxidizing.
Strip the wire shielding off a bit longer than the size of the contact you want to solder. Twist the wire and put flux on the surface you want to solder and tin them.
Tinning the wire is just applying a small amount of solder to the wire as to hold the strands together and make it easier to transfer the heat and solder to the contacts. Now mach the pin-out to the weirs to the contacts and put flux on the contact you want to solder to. Clean the surface by applying flux to it.The surface will be oxidized and will not let you transfer heat or solder to the surface. The key to soldering is to use the right amount of heat , solder and time you hold the iron to what your soldering to. You want to make sure you touch the wire and the contact you are soldering to as to transfer the heat to both items at the same time to make the solder flow. Put the solder wire to the tip of iron that is touching the wire and contact and not on top of the iron tip. Any time you apply heat to solder joints you want to use flux to keep them clean and free of oxidized material. After you solder check the solder joints for cracks, uneven and dull surface. You want the solder to look as shiny as possible and smooth. If it looks like it has waves or holes and cracks it means you have a cold solder joint and must reheat and apply flux with a small amount of solder to fix it .Here is a link to help you out this is not my site and full credit goes to the owner of site. How To Solder Soldering Tutorial Also put a link to a new cord if you decide you want to get a new one. Here is a link that may or may not help with the pin-out. Also not mine it should credit the poster on the forum as he did all the work i just found it PSP Go Cradle mini USB Tutorial with Partial Pinout PSP Go Acidmods com

get a lower melting point solder
get a higher temp tip if so equiped
get a higher wattage iron.

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!

Christina, It's probably dirty, and dirt is lousy for transferring the heat from the tip to the solder. With the iron hot, wipe it on a wet rag. This should immediately remove the black crud and make the tip shiny. Keep a wet rag handy to do this often if you are soldering for more than a couple of minutes. If the crud is too bad, you can use a bit of soldering flux on the tip, then the wet rag. If that doesn't work, you can file the tip (easiest when it's cool) until you have copper showing all around the tip. Please vote if you found this helpful. Good luck, Al K

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

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.

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!

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.

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.
