SOURCE: Weller 8200 series soldering gun sometimes fails

There is constant maintenance needed to keep soldering, the key ones are the tip fastening nuts, and the tip itself. The tip eventually needs sanding and immediate retinning, Clean with damp rag during and after each soldering event, and heavily re tin at end of event.

I need a wiring diagram for the trigger mechanism for a POWER-CRAFT soldering gun model 84 TWL 6091A.


You need this part: Weller 7324 Switch for Dual Heat Model 8200, D550 and D650 Soldering Guns That will repair the unit. Wire diagram is inconsequential .

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

I have a wagner power painter 355E and the directions said to put oil in the 2 holes in the gun. Where are the 2 holes?


Where the raised tips of the tubing goes into the gun,
directions state ,"Apply a light coat of oil."Tip sprayer up side down (so handle is sticking up) and the underside where the two holes where the ditting dual hose go in there: This is where you put a small amount of oil into both holes and trigger the sprayer briefly

It will not heat up, maybe tip needs to be cleaned, if so how? I lost the manual. Thank you..


I am assuming that you installed a new tip. Note, the tip ends have to be 3/8 of an inch 90 degree bend so that when you insert the tip leads into the barrels, they go into the small holes in the barrels. Also note, the nuts to tighten the tip into the gun have to be installed onto the tip leads before bending the leads. Now when the tip is installed this way, the nuts tighten and hold the tip in the barrel. This tightening of the nuts allow the tip to have a good electrical connection to the barrels and this is what allows the tip to heat. You actually have an electrical current that passes through the barrels and the tip. It is a very low voltage (around 2) but a very high current. Over time the tip will not heat, this is a sign to either tighten the nuts, or look at the tip to see if it has a break in it. If it has an open, then it is time to change the tip.
