Hello, just loosen the set screws on the end of the soldering gun barrels. Install new tips and tighten the set screw--sung! If your soldering iron requires that the tips have a 90 degree angle on their ends. You can bend them but be very careful because you can break them end off. The tipes are made of copper with some other alloys and the are kinda brittle. You can do. GB...stewbison

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

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!

Turn it on long enough to melt solder, then switch off for a short time. Repeat this process as you solder to avoid oxidizing the tip and solder, yet keeping the solder fluid. If it starts to poorly heat the tips, tighten the tip nuts somewhat to break the oxidation that occurs on the bare copper. Hope this helps!

There is a bimetalic strip and a magnet that can get stuck in the closed position. Tapping the iron on the end of the bit can release it otherwise a new element will be required.

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.

Sounds like main transformer is bad or bad connection. Unplug it and take it apart and check for loose connections. Good luck.

If element still heats up then only the bulb needs to be replaced. "https://www.6ya.com/philip_b05beb373d913f26"

I am looking at my Weller Portasol P-1k unit right now. They use standard flints. Go to almost ANY store you can think of and they sell lighter fluid and flints (usually sold in a pack of 5). About a buck or two.

nice to know what is wrong with it

Yes, 9 times out of 10 its' the thermal coupler.
