I have an old Weller soldering iron model 8250a that I would like to repair. It has burnt up wiring, and I'd like to find a wiring circuit diagram, schematic or ANY kind of electrical drawing, comple



These were very simple and sturdy soldering guns [I still have 5 or 6 of them in various sizes] They basically have a transformer wired so that the heating part is basically a short circuit of the large low voltage secondary winding [very low voltage] and because the tip is higher resistance than the rest of the heat producing end, it gets hotter sooner. The secondary is just a single loop of the tube that holds the tip. Usually the only maintenance is to loosen and re-tighten the tip mounting nuts so that there is a good electrical connection [no connection = no heat; poor connection = poor heat]
There may be another small secondary winding that provides power to the light but I think the older ones just attached the lighting wires to the large secondary.
The primary [line voltage] winding of the transformer is switched such that the higher wattage powers the lesser resistance part of the winding and the lower wattage powers the higher resistance part of the same winding. In other words there is a single wire for the primary that has a tap near one end of the winding for dual heat.
If the two windings to the switch are mixed up the higher heat will just be at a different trigger position; if you don't like it, switch them around.

Also check the connection to the non-switched wire from the cord for a good connection. The switches are still available, at least for the newer models; do a google search for

Is there good operating instructions, or manual for Weller 8200 N 100/140 watts gun?


There are normally three of the same type. They are consumable, you don't need to stock all the different types - just buy the one you need for your current project.

Note, these are high power and were commonly used for soldering wires in the point-to-point wiring used in old tube electronics. Do not use this on a Printed circuit board - it will damage any silicon component.

Use a a soldering pencil for printed circuit boards.

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

How do you use an weller wsb25hk change tips?


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

How do i use this product(Weller model Standard 7200)?


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!

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!
