    Well designed, fairly priced cordless soldering iron. I bring just the iron in my tool bag for quick field repairs and connections (mainly audio), and the rest of the time it sits in the charger by my workbench for small jobs. The fast heating is great, although controlling the temperature takes some practice. I’m very glad to have finally cut the cord on soldering.

      Thank you, Daniel! It is great tool for field work.

      Happy Soldering!

    I recently bought a 7700 because I wanted to have 2 cordless irons ready to go when I have a lengthy soldering project. My 1st cordless was (and is) an orange colored Model S.I. that I purchased over 40 years ago. I think it was around the time that Wahl Clipper first introduced the cordless soldering iron in the early 70’s. After years of disuse, I needed to change the battery and the bulb and I’ve recently retrofitted the charger to operate from a 5 volt USB port (not that the original transformer didn’t work just fine). Now it works just as well as the new 7700, even if it doesn’t look as good. I love these soldering irons.

    Now I’m rebuilding an older red colored 7800 to see if the “60” minute charge time is of any value to me. I don’t really need a third Iso-Tip, but you can’t have too much of a good thing and they do make a colorful set. Please don’t ever change how you make these irons. What worked in the 70’s, still works today. I would’ve even preferred that you left the old screw base (E10) light bulbs alone. The current model bayonet type is more expensive and can’t be found at your local hardware store like the old ones still can.

    I’m just glad that Iso-Tip lives on, still being made in the USA and remaining true to it’s original design. Doesn’t get much better than that. Keep up the good work.

    I bought my first unit over 15 years ago to keep on my boat and it still works. I just purchased another one to keep at home so I wouldn’t have to go the marina to use it. It is my go-to soldering tool even though I have wired ones available….hard to beat with the micro tips.

    HI all,

    I recently ordered the 7700, and have to say WOW. Anyone who conducts soldering on a regular basis should purchase one.

    I conduct a lot of audio repair, PCB work, binding posts, crossovers, ect.. This iron is fantastic. The iron is ready for work in 10 seconds, no need for me to have to move my full station, no cord to deal with, and the performance of the iron is amazing. Has no issues transferring heat even to some large 10awg wire.

    With that being said, I decided to test it out against the Hakko FX-901. The 7700 out preformed the 901 in every aspect I could throw at it. The tip design on the fine tip, transfers heat like a pro, the 901 just is not up to par with the 7700. The lamp, how did I ever live without a lamp attached to the tip of my irons! Swap to LED? No, dont bother, the standard lamp is perfect. the 901… No lamp.

    Heat up time 10 seconds, the 901 is about 20-30 seconds.

    I have nothing against Hakko, own a few of their irons. But all of that is now out the window, the 7700 will be replacing my main iron.

    If I were able to give the iron 6 stars I would.

    Kind Regards,

    Many years ago, I had the ISO_TIP cordless soldering iron (orange colored). It always worked great. I recently bought the model 7700 and an extra pack of tips for fine soldering (7451). It works just as good as the first one. I use it mainly for electronic projects and circuit board repairs. The thing I like about this tool is no cord to mess with and you can flow solder in about 10 seconds. If you guys are still around, I will buy another one in “many years” when this one wears out.

    The Iso Tip 7700 performed according to all specs. It heats up quickly and works well on solders in small tight places. I highly recommend it.

    I bought an orange 7700 over 20 years ago and it still works. Only a battery change using standard NiCd from a local store in my country.
    The BEST iron!!!

    i purchased a 7700 orange iron in 1986 in one store Manila, PH but unfortunately the store stop selling Isotip iron and no way to replace the worn-out tip and battery so i just kept it in my drawer long time ago. I think i can put it in service again. I can replace Ni-Cd cells locally. It was a nice iron, quick heat and handy. I missed it. You were then at Sterling, Illinois.
