A good product. I bought this one to replace the old one I had owned for about 8 years. It finally quit working after being dropped a couple of times. It heats quickly and will readily solder up to 8ga wire. I have also used the cutting tip to weld plastic and cut nylon cord. It is important to keep the tip clamp screws tight. If it doesn't heat up properly (less than 10 sec) then the clamp screws probably need tightening.

I have had Weller soldering guns for many decades. I ordered this one and found that the lights did not work unless I pushed them in (shorting to the core). Return was great, but the replacement had the same issue. I disassembled the gun - 3 screws, and was dismayed at the poor quality workmanship. There was a piece of wire about 3" long floating around and many clippings. I cleaned it up and checked the light voltage (4 Vac) across both lights, but no light. The light bracket was so cheap. The solder joints were terrible.
I returned for a refund - this process works very well.
I am afraid that offshore manufacturing is somewhat variable and unless we push, it may not improve.

I have owned the Weller D550 Professional gun for years (260/200 watts) but it just wasn't up to the big jobs like soldering starter brushes and 14 gauge (and up) electrical wiring. I was hesitant to buy a new unit with only 40 more watts but it made a noticeable difference in warm-up time and in heat applied to the solder joint. The D650 Industrial Soldering Gun also seems to have heavier windings and is physically a bit larger. I haven't tried it on sheet metal yet and would be interested in others experiences. It is important to read the manual supplied, especially the part about re-tightening and cleaning the tip occasionally for best operation. Highly recommended.

I got this to replace an old, lower-temp Weller 8200 N. Compared to the 8200 this gun is a bit heavier and does get hotter. It works well when working on antique radios that have aluminum can capacitors soldered to the steel chassis. High heat is needed to get a proper ground between these 2 metals that really "can't" be soldered.
Two design/ergonomics gripes:
1) The 2-position switch is counter-intuitive. You squeeze it half-way for the HIGH setting and all the way for the LOW setting. Makes no sense. And holding the trigger half-way is awkward. I would prefer a Hi/Lo switch on the body.
2) My old gun used nuts to hold the tip and these were very secure. New guns use set screws that are adjusted with an Allen wrench (not included, btw). These come loose easily and need to be tightened every time you use the gun or the tip will not get hot. The old style was better.
Believe it or not there is a web page devoted to collecting soldering guns. Actually pretty interesting and it did warn about the set screws. See "Steve's Antique Technology" at [...]

I read the reviews before buying this D650 model soldering gun. Had a Weller gun that worked well from 1953 till 2007. In the 50's it was used a lot to build 50+ Heathkits and many other projects. In the latter 47 years it did the job for more occasional wire soldering needs. Only maintenance needed was one cord replacement, a few tip and light bulb replacements, and occasional tip tightening. When it finally died, I bought a low wattage Weller gun and was always frustrated by it's slow heating and not enough heat to solder even simple 14 ga. wires. After getting this model, eager to try it, I felt like I had my old trusty dual heat gun resurrected - only better, since it heats up very fast and proceeds to do what I ask of it. The 5-star reviews were right. It is a bit heavy in the hand, but it does the job - and fast! The price was an unqualified bargain, if it lasts as my original Weller gun did. (I'll will it to one of my grandsons.) I'm very pleased with it and thankful for the reviews which directed me to this model.

I have bought several of these from various vendors for use in a small appliance repair shop. The lights of course never worked but more troublesome, the switches failed very quickly. In one, the switch started internally arcing and burned the technician's hand. In the other, the switch just fused itself on and the soldering gun turned on by itself. Very Dangerous. If you have any of these, be sure to ALWAYS UNPLUG IT between uses.
I haven;t be able to find any other soldering guns that work so well, when they work however, (we used to use the WEN 250, but that's not made anymore), so we keep putting up with it's flaws.

I purchased this soldering gun to install connectors on larger coaxial cables. First thing I noticed was that the light does not work. Second, the internal transformer seems to be loose because I can feel it flopping around if I shake the gun. It DOES solder adequately though.

I just received my new Weller D650 soldering gun via FedX. It was packaged adequately and arrived in mint condition. I was leery about the new tip connectors but they are an improvement over the old style. The new type of plastic housing is also an improvement over the older brittle plastic that would brake when the soldering gun is dropped (and believe me it will happen some day). I plugged it in after reading the instruction pamphlet, and tined the tip. This gun has a lot of heat available for soldering large wires (or coax pl259s' etc.). The head lights work just fine, in fact the fit and finnish looks good, much better than it looks in the photos. This gun replaces my 30+ year old D550 that I lost in a fire. This is a much heavier duty than the old D550. If you were hesitating to purchase a D650 because of some of the low ratings from some reviewers, DON'T, this is a fine product that will give you years of service.
