Weller W100PG Weller Farenheit Heavy Duty Soldering Iron with CT6F7 Tip, 100 Watt, 700 Degree, Original Version

Weller Iron guide – A good iron; info and comparison with Hakko iron
Excellent iron for stained glass work. I’ve used both Weller 100W and Hakko FX601-02 in my 20 year long career in stained glass, both as a hobbyist and as a fabricator in a professional studio making church windows. If you’re considering between the two, here’s a quick guide and info:The Weller is a sturdier iron but heats up a little slower and is harder to control as it heats up to a temperature and stays there. The temperature is determined by the tip – the base of the tip if you remove it from the barrel has a letter on it and that shows what temperature it will reach and maintain. You have to be able to adjust and control your heat by how you use the iron (For example, too hot? Dump some heat by cleaning the tip on a damp sponge. Too cold? Wait a little bit for it to get up to temperature again before continuing. That sort of thing. I never bothered with a rheostat for this iron as I could control the temperature manually and I heard that it can shorten the lifespan of it as the iron temperature is determined by the tip.) I’ve used it and abused it in a professional setting and it holds up well, very durable. It’s a slightly heavier, bulkier iron, so it’s easier to hold as you’ve got more weight and is much less prone to fumbling but also means slightly more hand fatigue. I use a Hakko now but will be buying another Weller as my old one bit the dust after many years and I still like to use the Weller for heavier duty soldering jobs on my glasswork and it works better for repairs when I have to disassemble older projects.The Hakko has a rheostat built in, so you select the temperature you want based on the dial setting so it has much finer temperature control. It’s a lighter iron so it’s easier on the hands but also easier to fumble it and it’s ceramic so it has the benefit of heating up very fast, faster than the Weller, but the downside is that it’s more fragile. You shouldn’t drop it as you can shatter the ceramic element.If you want something durable that will give you a goodly amount of steady heat, go for the Weller and learn how to control your heat manually. If you want very finer control for more varied uses go for the Hakko but be gentler with it. Both are well worth the price!To address some comments I saw on here:- The barrel turning colors: That’s normal. It heats up to 600-800 degrees Fahrenheit, that kind of heat will discolor the barrel where the heating element is. This is not a fire hazard or dangerous (beyond the fact that it’s a soldering iron and they’re meant to get very hot) – it’s expected behavior of the iron.- Iron is being sold as new when there’s clearly solder on the tip showing it’s been used before: If the barrel is silver and doesn’t have a discolored band around it, it’s NOT been used before. It’s expected to have solder on the tip of it. All the tips have been tinned, which means they have a coating of solder on it to begin with. That’s normal and expected and does not mean the iron has been used before or isn’t new. If the barrel is silver it’s new. If it’s got a brown band from heat, then it’s been used.- Smoking when soldering: That’s normal. Flux burns and produces smoke when soldering. Also, the iron also might smell/smoke after first use since it may have dust or a thin coating of oil that burns off on first use. Please be safe and use a fume extractor or a mask to protect yourself from smoke. Lead doesn’t burn at these temperatures, it’s the flux burning but still smoke is bad for lungs, please wear proper protection or have proper fume/smoke extraction.- Tip gets dirty when soldering: Yes because flux burns and residue from what your soldering on can also build up on the iron. Clean it off on a damp sponge. It’s normal and expected.- Needing to re-tin the iron: That’s normal and expected of all soldering irons. Depending on what you’re soldering, you may need to re-tin more frequently than normal. (Repairing old Tiffany glass projects for example is rough on my iron and requires frequent re-tinning when tearing apart broken projects.)When to know your iron has an issue:- It doesn’t heat up/doesn’t heat up enough to melt the solder- It’s making unexpected noises. It sometimes can make a faint ticking sound from metal expanding when it heats up, especially as it gets a lot older but it shouldn’t be making any other noises like whining, knocking, etc.- It’s fallen apart into multiple pieces or the twist cap that affixes the tip to the barrel has split into two pieces and no longer holds the tip in.- Smoke from inside the iron (instead of at the tip when soldering)- Trips breakers or shocks you(Note: I’ve only ever had the first three happen, and all of them from age and hard use. I’ve not the last ones in this list ever happen but I could see it being a possibility if you got a defective iron.)Other advice: The tip that comes default with this is too large for every day use. It’s mostly good for soldering supports or heavier duty objects. Getting a smaller tip helps a lot. I think I use the 1/4″ 700 degree tip.Hope this guide helps some people!

Updated: *Works* but used and potentially a fire hazard
Update: After some desperation, I plugged the iron back in two days later and waited. No smoke, no smell, seemed okay. So i finished a large project with it and it worked well. I’m not sure what to say; I guess I’ll keep it. Do soldering irons have like a breaking in period? I changed my stars from 1 to 4; it was a dramatic start so I won’t give it a 5 but it seems to work for now so we’ll see.I bought this iron despite the reviews that stated it may be used because I have a stained glass project due this week and thought that used may not mean bad. When I received the iron, it was clearly opened and used because the package was opened along the side as if it was slid out as discretely as possible (which is more suspicious than just the idea that someone opened it, used it, and changed their mind). Also the iron tip clearly had solder melted on. Again, I decided to give it a chance and plugged it in. It started smoking, had a sharp chemical smell, and I watched the neck turn from silver into amber and then purple. It started making a crackling noise so I immediately unplugged it because I was scared of a fire hazard. Please, please do not take a chance on this seller.

Exactly What I Needed
I service and build tube guitar amps. Working with chassis grounds requires an iron that can generate quickly the kind of heat needed to get the job done perfectly. After trying several different irons/guns for this task, I arrived at this Weller. Having the right equipment to do a job is a priority for me. This Weller is really impressive.

The best
I use this for my art of stained glass. My last Weller 100 lasted 25 years and was used a lot in my business. When I bought it before it was made in United States now it is made in Mexico hope it holds up as well. So far it is working great and keeps a constant temperature perfect for stained glass.

Ça fait plusieurs années que j’utilise ce fer. Fonctionne très bien mais là il a rendu l’âme. Donc j’ai commandé la même chose. Très bon fer à souder pour le vitrail. Très satisfaite.

Works great
