I bought a new Weller some months ago and it worked straight out of the box. Today is the second time I needed to use it and it would not heat up. I considered cracking the case and going in, but decided to take a look here on the tubes to see if anyone had a similar problem. Your video directs attention to clean contact with the heating tip. So I took a look and right away discovered the problem. The securing screws were snug enough to keep the tip from pulling out, but not tight enough for a good electrical connection. Thanks for Step 1.

I've had a Weller soldering gun for years, which has never worked properly, even when new. Despite thorough cleaning of the tips and connectors, the gun would only work weakly and intermittently. I replaced the switch, to no avail. This video finally gave me the info necessary to fix the problem, but there's one more step to consider, which was my ultimate solution. The problem is that the aluminum oxide layer on the connectors is a terrific insulator, and difficult to thoroughly get off. I dipped the gun tips and connectors (dismantled) in a dilute 4% sodium hydroxide solution - diluted "Drano", or lye - for about 60-90 seconds, until the aluminum appeared slightly dulled. That removes any anodized surface on the aluminum, and makes for a much better connection. (Of course, be careful with lye - it burns the skin, and can be very dangerous - read the precautions on the can). My gun has worked fine since then...

I have a Weller D550 that I got as a kid in early 80's and recently it's performance has tanked, lights quit working, etc. I even swapped out the tip for a new, old original tip and had the same performance. I didn't notice all my tips were heavily oxidized and a quick clean up with a small file back to shiny copper and viola! My soldering gun is back; even the lights work again! Thank you so much.

YuDaMan, you are the man!!! I was just about to take apart my Weller 8200 and decided to check KZbin to see what could be the problem. I took of the tip cleaned it and pushed it all the way in and tightened it. Problem solved! So happy! Now i can fix a bunch of stuff that"s been sitting around for awhile...

I wished I had seen this video before :( I just bought a replacement soldering gun, but my old just needed a new tip. The old tip was rusted inside and I learned from the video how to fix it. I also got in the bad habit of pushing the gun clicker too tight and the gun would not heat enough. This video was a refresher as I had not used the soldering gun for a long time. Bottom line is I have two soldering guns now.

Excellent video. I always thought the trigger arrangement was weird, but maybe the designers noticed that people often tense up doing fine work and tighten their grip. To prevent unconsciously overheating the work, they damped down the voltage on tighter trigger pressure. Presumably the opposite, relaxing the grip, wasn't considered as much a problem given that fatigue is uncommon in soldering. Besides, there are limited options using a trigger mechanism to control voltage.

Thank you. My father left me a Weller 7200 along with a few other things, but it would take 10 minutes to heat up. Not an exaggeration. I was loathe to throw it away because of whom it came from. I did what you basically show, except with a smooth file. Tip starts smoking almost as soon as I pull the trigger.

Thanks for the excellent suggestions. If you haven't done so in another video, any advice on cleaning up and re-tinning the working end of these tips while you're at it? P.S. For those viewers who work on modern cars, remember the effect of small amounts of corrosion on the power, ground & network connections to and between the numerous electronic devices that control your vehicle. These control circuits typically have a maximum 5 volt power supply(called a reference voltage), and depend on continuous monitoring by various computers of accurate measurements of very, very small variations in voltage to make everything work properly. Corrosion can be caused by weather, water or chemical intrusion(i.e from salt-treated roads), loose connections, ground connections covered by any sealant which can trap water and allow unseen corrosion under the sealant layer, and, surprisingly, by continual vibration of otherwise tight connections (sometimes referred to as "fretting corrosion").

Great video! I took my top of the line SEARS solder iron apart because the bottom cylinder came off. I could not get it back on, because it was fouled with solder. Took it apart and removed the solder with a solder pen. Now I cant get it back together. Problem is, I don't know how the sequence if the wires to the trigger. There are 3 wires.. red, yellow and black. From top of gun down, hiw should these go? Should of played better attention when taking it apart. Is there a schematic available somewhere that would show how they should go? Sorry for the drawn out messege. Have a safe and Happy week!

I have a Standard Weller 7200 Soldering gun that I thought wasn't any good any more for all the reasons you've touched on in your video. I have some new tips on the way but, I wanted to ask; when I put my multimeter to it (had it set for amperage) it read .012-.013 amps. It won't read anything if I set my multimeter to volts. Admittedly, I'm not the brightest bulb in the shed when it comes to electrical current. This Soldering gun is rated at 1.0 amps according to the side panel info. I'm not really sure if the designation "7200" denotes that the watts that this Soldering gun runs at is 72 watts but I was hoping you could clue me in on what, (assuming this Soldering Gun does actually work) to expect in the way of output voltage when I put my multimeter to it? I did take it apart to check for broken connections and everything appears to be properly connected with no tell tale signs of short circuit burn marks and such. Hope that makes sense. I'm hoping you're right that all it needs is a properly installed new tip. I was curious about the output amps that my multimeter was giving me.
@YuDaMan
@YuDaMan 6 жыл бұрын
I recall the current (amperage) is quite small. My irons would work great for a very short time with new tips. A thorough cleaning of all the contact areas on your old tips will give you surprising results!

Tried this with a D550PK kit from Amazon(👎🏻), but it did not work for me. I used the gun ONE TIME soon after I received it - worked great! Then it sat for about a year and a half in the closet. Took it out to solder some speaker wire ends and NOTHING. No feeling of slight vibration when pulling the trigger, no lights, nothing. Of course Amazon only says it's non-returnable because of the length of time that I've had it. The case and gun both look brand new! PLEASE HELP!

**************EDIT************** Switch was compromised! Looked like lots of green oxidation inside. I could not take it apart like I've seen in other videos because the new switches have rivets instead of screws. I sprayed a bunch of Deoxit into it alongside the red plunger and worked the switch quite a bit. That did not work. I let it sit for a while and then sprayed the inside with lots of CRC electronics cleaner. Again, I worked the heck out of the switch and finally it started coming on again when the switch was pulled.

What is this gun type called? I’ve never successfully soldered with it. Had it since childhood. 100 watts, I thought Tandy made them for everyone but mine is RadioShack at least. It has a bit long rounded tip, like a full 3/4 inch maybe. What is the purpose of them?
