If a connection is made incorrectly, you’ll need to use a de-soldering braid or a solder sucker to remove the solder and reconnect the components.

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 just bought the soldering gun but the instructions on the package aren't very useful how do i use the gun?

A soldering gun is used much the same as a soldering iron for melting solder mainly to connect electronic components to circuit boards. To use it you plug it into the electricity mains and press the trigger. This causes the metal tip to heat up. Allow a minute or so for it to reach full heat and press it to the components you want to solder together. When they heat up press the solder against them. The solder melts and runs on and between them forming a bond. Remove the soldering iron and release the trigger. Once the trigger is released the gun starts to cool down again.

If you've used a soldering iron before you'll probably find the gun more awkward as it cools down every time you release the trigger. It's really only useful for quick jobs where you're not going to need it every few minutes. For other jobs where a lot of soldering is involved a soldering iron is better. The advantage the soldering gun has over the soldering iron is that it heats much faster for quick jobs.

I bought the gun years ago and never used it. Now I need to solder my eyeglasses frame and have no idea ho to do it. How do I start? It's a dual 140/100 watt gun

Often the material used for eyeglass frames will NOT take solder.
If you want to try soldering you likely will need a flux that has zinc chloride. You should probably use a harder solder like StayBrite. You put some flux on the joint which needs to be held fixed while soldering. You heat the joint with the soldering tip and apply a little of the solder. One should "tin" or wet the tip before using by applying flux to the tip and melting a little solder on it. Search YouTube as someone probablly has a video on soldering.

Chances are that the screw and maybe the hole in the iron barrel have been 'cross threaded'. Remove the screw and the tip, then examine the screw and hole threads for thread damage. If they are, the screw should be replaced, but the hole in the barrel will need to be cleaned with the proper size tap. You can find the tap and the screw at a home center, or hardware store , plus get some suggestions on how to fix your problem. Hope this helps!

Just loosen the screw in the barrel near the tip, then rotate while pulling the tip out. It shouldn't be necessary to remove the tip unless it requires replacement. Hope this helps!

Tip screws for model 8200 are worn out, What is the screw size?

The tip screws are a drilled bolt for this unit. There isn't room to tap the barrel holes out further if the threads are bad. You used to be able to buy tips that were pre-loaded with the proper clamp bolts. Good luck!

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 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 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.
