Weller transforms hand soldering The art of hand soldering has been around for a very, very long time, thousands of years in fact. But it was only until 1941 that a transformer based instant heating soldering method was developed by an impatient American radio repairman who was tired of sitting around waiting for his soldering gun to heat up. Carl E. Weller had to wait until after WWII ended in 1945 to get his Weller Manufacturing Company going. In 1960, the Weller Manufacturing Co. in the US patented the “Magnastat” soldering iron which used a magnetic component to regulate the temperature at the iron’s tip. In an expansion overseas beginning in 1959, the Weller GmbH plant in Besigheim, Germany, along with new plants in other countries, was organized to manufacture temperature controlled irons and soldering guns for primarily industrial markets throughout Europe and the Near East. Keeping pace with the increasing complexity of our customers’ needs, Weller Germany became the market leader for developing and manufacturing hand soldering products worldwide. Our products were proudly emblazoned with “Made in Germany”, signifying innovation and reliability.

Dispendieux et pas beaucoup de pointe utile pour les travaux de précision alors j'ai du acheté des pointes séparément au coût de 25$ chacune. Mais je sais que c'est un très bon fer à souder car il remplace mon ancien qui était exactement le même modèle. l'ancien avait beaucoup fonctionné , il à servi pendant 6 ans à 40h00 semaine dans une boutique de réparation électronique alors oui il à servi beaucoup. C'est pour cela que je sais qu'il est un très bon fer à souder.

To early to tell yet.I’ve had one like this for years used it a lot it started to go faultySo I took the plunge it’s expensive but from past experience hopefully it lasts as long.My only dought is the hinge on the lid it looks frail but we will see. I have filled it up and tried itIt fired up straight away.I will leave an update when it’s been used in anger 🤔🙏

Great iron, replaces my VERY dependable 25 year old pyropen. Lights easily but could use a basic flow control. Tips seem good, as is expected from Weller. The case is odd to me, the lack of storage for even a small hand coiled length of solder is a missed convenience, I suppose I could put it inside the round tip cleaner if dry. Similarly the heat shrink deflector has no storage spot in the case, it must be kept on the heat tip on the iron or left to flop around in the space for tip storage. The heat tip can be stored properly, the deflector cannot. Small gripes...The performance of the iron is excellent, tip prep is of course required as with any new soldering iron tip. This iron can get very hot, just like the original, so extended use (15min +) should be watched. The housing glowing orange, easily seen in low light conditions, is a pretty good indicator that it needs a break! Note: your tip needs to be taken care of in those extreme heat cases of extended use, it should cleaned and retinned as it cools down or the tip will oxidize, (possibly to unusable - my own mistakes taught me that one!!)Great tool I recommend it!

This is a replacement for the exact same tool that worked hard for 27 years until the fill valve gave out. It served me well throughout all that time. Heats fast, reasonable gas use. Well working (manual) power control. Everything you would want in an off-grid soldering iron. (Or even on the grid. It is so much easier to have this in the drawer, than setting up a soldering station when you need it.

I have purchased several low cost butane irons and all of them were made cheaply. While nearly everything at low cost today seems to be made in China, some China production is truly worthless junk that will fail shortly & you with no replacement parts to be had from anywhere. My last $30 iron was one of these & it looked wonderful but the metal was so soft it deformed when hot and low pressure applied to the tip.I am a Ham Radio operator 300 feet from the ocean and have migrated from lead based solder to the lead free versions which will not oxidise as readily near salt water. This requires a higher heat as some of the wires are 14 gauge and the connectors are substantial. Being far from electricity the only way I could get the power to solder was to use a 1,200 watt inverter and power it from a motorcycle battery and then use my Weller electric iron to do the job. A lot of work and the battery did not last long. To carry a deep cycle battery out to the different antennas is not realistic.This weller Iron does three particular things for me; It melts the plumbing solder quickly. It has a very effective adjustment valve for the gas (heat) flow and it is solid as a rock. More, it starts easily and the controls are effective. I rate this 5 stars because it does what I bought it to do and it does it well. It is NOT a 250 watt equivalent iron and I don't know if there is one for butane that gets that hot. I would like one assuming it also went down to as low a temperature as this one but I don't need itCons: The product itself is just fine. You do need to remember to shut off the gas by using the on/off "switch" as at the lowest valve setting there is still a miniscule flame that endures and will remain lit while you put the iron away. I would like to see a metal sheath for the tip to fit into that will snuff out any flame when putting the iron away in its case, one affixed to the case that requires the iron to seat into it to close the case. In case of user stupidity it would not stop the butane from running out but it would stop the heat.

This is the second Weller Butante Soldering Iron Kit I've purchased. I purchased my first Weller butane soldering iron about 15 years ago when I needed a soldering iron that could be used in places where there wasn't electric power--like repairing a radar in a boat tied to a mooring. It does a great job soldering. However, I found the hot air source to be even more useful as the ideal solution for heat-shrinking even where power was available. For just a quick job of heat-shrinking a wire splice or single connection, a click of the igniter is way quicker than digging out a heat gun and cooking everything else in the immediate vicinity of your one little connection.Recently when helping my son-in-law hook up the driving lights on his rally car, he seemed to be casting covetous eyes on my Weller butane iron. Smart kid that he is, this was just before his birthday, so he got his own as a gift. Incidentally, as usual Amazon had a much lower price for this than the usual industrial supply companies and the shipment was very fast. All in all, it's a very useful, multipurpose tool that will provide year's of service.john

The PSI100K is truly the big brother to the Weller P2KC which I have happily used for some years. Both work well and are reliable, and both do a good job of containing the butane charge while not in use. The larger PSI100K is more than worth the extra $20 if only for the fold-out wire stand, just to have an easy option to set the unit aside without starting an unintended fire. The extra BTUs are also handy both for larger solding jobs with lots of metal to heat, and esp. for using the hot knife attachment for cutting plastics, trimming rope, etc. For just a quick one-junction solder, these butane units also heat up faster than my conventional AC powered irons.
