# 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.

Need wiring diagram or schematic of the primary, secondary, and lighting windings or a weller soldering gun. even arough drawing of the windings that's close would work


You know that's a bit goofy, right? Only the manufacturer would have such information.

If you are serious, you CAN do it. Begin with an accurate Ohmmeter to measure the primary and secondary winding resistances on a new gun (at Sears, say.) To do that, measure the new gun's primary resistance at the plug with the trigger pulled, of course. Remove the gun's soldering tip and measure the resistance of the secondary without the tip and any incandescent bulb in place. (No need to pull the trigger.)

Hopefully you have some of the burned wire from the old gun. Measure the diameters of samples of the burned primary (thin) and secondary (thick) wires with a micrometer. With that information, look up wire gauge information online. You may need 24 gauge and 18 gauge enamel coated wire, for example. Note: a burned wire will no longer have its enamel coating so take that into account when determining the gauge of the "new" wire.

Note the "Ohms/foot" specification for each wire gauge. Divide that number into the resistance values you measured on the new gun (at Sears...). That will indicate the number of feet of each gauge of wire you will need to rewind the core!

Now I'm off to build my own refrigerator... NOT!

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.

Need 2 know how 2 take temp of Lenk soldering gun model 2000.not sure if its getting 2 correct temp.whats temp supposed 2 be,in ferenheit?i have a Etex digital multimeter.really dont know how 2 use it...


It needs to be at least 600 degrees F and should reach 800 or so. 60/40 solder melts around 600, but flows better at about 700 degrees. Most soldering guns require a on-off-on--- sequence to keep the tip at proper temperature. If your gun doesn't seem to be heating, try tightening the tip nuts. 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 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.

Heat Guns Features


As such a simple tool, there are not many differences between one model of heat gun and another - but there are some features which are important. * Wattage - commonly from 1000W to 2000W (a measure of the power of the gun). Providing that there are heat and/or airflow controls, the higher the wattage, the better. * Main control switch - usually mounted on the front of the pistol grip, and normally a 'dead man' switch so that power is switched off when the finger pressure is removed - an ideal safety feature as the heat gun stops if it is accidentally dropped. * Temperature setting - at least 500°C is needed for stripping paint - the lower the bottom end of the range the more useful. A choice of controls make the tool more useful. * Airflow setting - having variable or more than one speed makes the tool more versatile. * Thermal cut out - this will switch off the tool if it becomes overheated. If this occurs, it indicates a fault in the tool or method of use - for safety, the fault must be identified and corrected before the heat gun is again used. * Flex length - lengths of 2.5 to 3 m are normally fitted, this means that when using an extension lead, the tool can be used at the full reach without having the socket hanging in mid air. * Hanging hook - useful for storing the tool. * Surface stand - this enables the heat gun to be safety 'rested' during pauses in the work and after uses. It also allows the gun to be used 'hands-free' when two hands are required on the work piece (such as when bending a plastic pipe). * Nozzles - most heat guns have a range of nozzles that can be fitted for specific uses, generally these need to be purchased separately. The main types of nozzles are: 1. Reducer nozzle - when you want to concentrate the heat onto a specific area. 2. Reflector nozzle - wraps round a plastic or copper pipe to spread the heat around the pipe surface. 3. Flat nozzle - for spreading the hot air over a wider narrower area. 4. Glass protector nozzle - for use when stripping paint on a window to keep the direct heat off the glass.
