Trying to solder components that haven’t been cleaned properly will result in weak connections. If the tip if the gun is not cleaned correctly, oxidation and deterioration may occur. Periodically running a lightly moistened cloth across the soldering gun during a lengthy work session is the best way to ensure crisp connections. However, you can also purchase special sponges and cleaning pads to care for your soldering gun.

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

My Dremel Versatip wont melt the solder - it gets hot, as I touched it to a piece of paper and it burned through, but why wont the solder melt?


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

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

How long to i leave it on


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!

Soldering gun maintenance


Start with a clean soldering tip. If it's a new tip, use sandpaper or steel wool so the metal shines. With an old tip, you may need to use a file to remove badly oxidized areas. Once the tip is clean and shiny, press the soldering gun trigger to high and as soon as it's hot, apply a coating of solder to the tip. Use a rag to spread the solder evenly over the tip. The materials to be joined must be clean, dry, and free of grease and oil. Use a wire brush or fine sandpaper to get the surfaces clean and shiny. Make a good mechanical joint. Crimp terminals with a crimping tool or pliers, and twist wires together tightly.

Soldering gun troubleshoot


# Never touch the tip of the soldering gun. They are very hot and will give you a nasty burn. # Take great care to avoid touching the mains flex with the tip of the gun. The gun should have a heatproof flex for extra protection. An ordinary plastic flex will melt immediately if touched by a hot gun and there is a serious risk of burns and electric shock. # Always return the soldering gun to its stand when not in use. Never put it down on your workbench, even for a moment! # Work in a well-ventilated area. The smoke formed as you melt solder is mostly from the flux and quite irritating. Avoid breathing it by keeping you head to the side of, not above, your work.

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.
