Overall, the glueing process is clean, as the pen doesn’t leave lots of trails like some rival products do. The nib is also small and precise, meaning it’s possible to place tiny amounts of glue for those really intricate tasks. This product carries a full 3 year manufacturers warranty covering both faulty materials and faulty workmanship, it does not cover general wear and tear or damage, batteries, blades, bulbs and other consumables. In the unlikely event of a fault the item returned is subject to fair wear & tear and must not have been used beyond the scope of it's design. Please note that cordless products will normally have a shorter warranty of just 1 Year for the battery and or charger supplied. It comes with a 3 year warranty, though you must register for this within 30 days of purchasing (same for all Bosch tools). The Bosch Gluey Evergreen Cordless Gluing Pen gives you endless possibilities to bring your creativity to life! The Gluey Evergreen is cordless working and is environmentally friendly thanks to rechargeable AA batteries. Finally gluing is fun thanks to the compact and convenient hot glue pen Gluey. You can expect precise gluing due to the optimized dosing nozzle for all your DIY tasks and projects. I love this glue pen. It was given to me by my Mum two years ago for Xmas and I've used it a fair bit since then. I've used it to make various glue art items, mostly book or journal covers.”
On the left side next to the micro USB there is a charger circuit labeled ‘3303’. On the top of the micro there appears to be a NTC used to monitor the temperature during charging. The holes are probably there in case a through hole termistor is used. There does not appear to be any form of electronic temperature regulation – even after 3 minutes since I turned it ON the device maintains 12 V constantly at the gate of the tranzistor, no PWM or anything. Although extremely simple in its design, the Bosch GluePen feels well built and sits nicely in the hand. There aren't many moving parts, so it’s not like there are flimsy clips or cheap buttons to let the side down.Much better than my old one that needed ~5 minutes to warm up for probably half a minute of gluing. I am very happy because of the fast warm up, wireless operation and small size. Battery should last 30 minutes and you get the low warning when there is 1/3 left, which I find enough. On the right side we can see the fuse and a IRF3711Z 6mΩ 20V HEXFET driving the heating element. At the glue melting end there is no temperature sensor, they are probably relying on the positive thermal coefficient of the heating element to achieve a rather stable temperature, as the manual quotes “approximately 170 °C”. Also there is a step up converter – used to generate ~12 V to drive the gate of the tranzistor, to keep it in the low ohmic region. Why internet is fast and cheap in Romania and some other countries (but expensive and slow in others) June 25, 2022 The wire going to the heating element is also connected to the micro, possibly to measure something, but what? Also the current through the battery while charging seems monitored by the micro as well, through the 0.22 Ω resistor next to the blue wire. The other negative is that the batteries take a few hours to charge for around 30mins run time. It comes with 2 Varta rechargeable NiMH AA batteries rather than LI-ION, but at least they'll be inexpensive and easy to replace and in a glueing emergency you can always pop in a couple of Duracells.
The device seems well built, has a good price and I am happy with it so far. It’s much faster to warm up compared to my old one which makes gluing faster. Enjoy a free 2 year guarantee, which can be extended to 3 years when the tool is registered on MyBosch.com. We also offer a 5-day repair service, we will collect, repair and service your product and return it within 5 working days. (Collection excludes UK highlands and islands).
This item is delivered direct to you from one of our suppliers, please see our Terms & Conditions for details. This is a great product overall. As per usual with Bosch it's very well made and easy to use. If you have something relatively small to glue (ie I used it to fix a Christmas decoration and my wife glued some interior trim in her car) it's just the job.
