    The main reason I don't like setting soldering irons to a very high temperature is that the flux tends to burn off before it makes it all the way around the joint. That makes the solder not flow all the way around even if there's plenty of heat. For soldering large terminals, I like to buy much larger tips with greater heat capacity instead of turning up the iron.

      I'm the same way. Regardless of solder, I detest coated brazing rods for the same reason. Plus coating the joint area with flux restricts solder flow to the joint, essential for high silver content solders.

    I used to work at a telephone exchange, and we had two types of iron. A large slow heat iron and a 50 Watt quick heat. The slow one could be left on all day and be usable for a couple of terminations, as it slowly went to about 360 deg C. If we needed to do a few hundred terminations we had to use the quick heat, which was about 450 deg C, but needed the oxidation cleaned off every 10 minutes. Also the tips would only last a fortnight before being needed to be replaced.

    Parkside do appear to make surprisingly decent budget cordless tools. About 5 years ago a friend gave me his Parkside impact driver, general purpose drill, and their SDS drill, as he had bought some proper Dewalt kit, and I used them for a good 3 years for DIY stuff, before making a return to carpentry for work. I figured they might see me through a few months on the job, until I could afford to replace them with professional stuff... Well, they're all still going strong and I've since bought extra batteries and a number of other tools from their range, and I've also discovered that, with a little modification, you can even run the Draper Storm Forcce range, with the Parkside batteries (it looks suspiciously like Draper use the same manufacturer in China, or at least many of the same components). People are always laughing at me on site for using Lidl tools, but those who work regularly with me, have had to grudgingly admit that they're actually pretty good, dependable tools, and of course the batteries are less than a 3rd of the price of Dewalt ones 🙂
    A while back I started to wonder why they were so well built for the price, and I found out that it's all down to regulations in Germany, where Lidl are based, as they have to ensure that their power tools comply with a set of semi professional standards over there. Anyway, great video mate, always a pleasure to watch your teardowns of stuff like this 👍

    Hi Clive.. thanks for bring back memories with the Antex iron.. when I was a young lad getting into things electronics, I got 2 different birthday presents that I still remember… my mum, under my directions, got me an Antex iron and when I turned 21 my sisters got me a set of Stanley screwdrivers.. now 45 years and a bit more I still have both gifts.. apart from the “electrical” screwdriver, with the red plastic insulation, the set still has all the original screwdrivers.. I know were the original electrical driver is, but unfortunately it was in the roof space of a factory, that no longer exists..
    A cordless soldering iron is a super “handy dandy” tool to have.. only yesterday I got a bit of kit up and running, situated several hundred metres from the nearest powerpoint, with a quick dab of solder!!
    Keep up the good work… cheers

    God bless this video. I've been searching for some time for a cheap, but not totally rubbish portable soldering iron. But I've never came across for those with adjustable regulation. The fact that this soldering iron is so easilly modifiable makes me happy. So I am instantly buying one of those and I just have to add 100ohm potenciometer. I just hope that the available model PLSA 20-Li B2 has the same PCB and they didn't removed the posibility to add potenciometer for regulation.
    Also in Czech Republic this product is available on online Lidl shop standalone without battery and charger for 500czk (about 18Ł) - without shiping. Extremely good value i think, if you have other parkside products with 20V batteries.

    I bought one of these a couple of years ago and it worked for around a couple of months then next time I went to use it had failed. The LED does all the right things, flash and turn green, but the element does not get hot - so the "warm up" indications are time rather than temperature sensed!
    I tossed it in the bottom draw but now with the help of BC's excellent reverse engineering I'll go and check it out some more - it's probably the element that is broken.
    Like BC I actually bought it with the intention of using is as a battery connector for my TS100 - which I will still do by installing a connector from the unit.

  • @adamf663

    One trick I learned when building a computer kit in the 70s is to continuously feed solder while going down the pins of a DIP socket. The capillary (?) effect causes the solder to pull along and not leave bridges. Super fast. Any bridges can be removed in a quick second by running the soldering iron over the pins top to bottom and removing the excess on the iron's tip. My current irons are a SainSmart TS80P portable soldering iron with a usb-c battery brick, and on my bench, a Hakko FX888D-23BY Digital Soldering Station. Once you go temperature controlled, you never go back. They come up to temp like a 1000w iron but stop at the selected temperature. On a recent car stereo project, I soldered all the connections (no crimp/butt connectors) and the SainSmart worked wonderfully.

I spent ages the other day trying to take the resistor off an Asda led bulb a la Clive's hack. The pigging thing was cooling faster than I could move my tip and there just wasn't room to get an ordinary tip at he right angle. About £50, I' be been toying for ages but finally snapped and paid up. Only took two weeks on Ali express and it is brilliant, you just grasp and lift and off comes the component no matter how nice the PCB there is enough heat to do the job. I think I'll get my money back pretty soon at this rate

    Actually, you can set what temperature you need on this PARKSIDE soldering iron. You just need to switch it on and wait the light indicator to get green. Then press and hold the button until the indicator goes red, this is the state of lowing down the temperature. Every brief press of the button will change the maximum temperature of the iron for about 3 degrees C. If you press and hold button until the indicator goes green, this is the state of getting up the maximum temperature. To save the setting, just press and hold the button on more time.
    I have two of these irons and set them both to reach a maximum temperature for about 365 degrees C. To measure the temperature you may use some thermometer like the one in the video HAKKO 191.

    A couple of years ago, after about 24 year’s service, my trusty Adcola t/c iron died.
    I tried a couple of generic Chinese irons: the first I sent back as it seemed useless for anything but the lightest tasks.
    Its replacement was equally bad and on examination I found the problem to be that the bit wasn’t actually in contact with the heating element. This meant it could only get as much power to the tip as could be radiated and conducted across this small air gap.
    So the tip would get hot while on the stand, but as soon as you tried to solder a wire to a 1/4” spade connector for example, it would exhaust the heat capacity of the bit before you could make a decent joint.
    Rather than send it back, I shimmed the bit with some copper foil to improve thermal conduction. This made a fair difference and I decided I could live with it. A year later the controller chip went faulty and the MOSFET turned to ash.
    I now have an Antex 660A. Like everything these days it’s made in China, but at least seems better designed from the thermal aspect.

    Thanks for this analysis of a very useful and well-made soldering iron. I was wondering about trying to lower the bit temperature and you have now given me the answer. Re labels covering joints - I usually carefully slit the label along the joint with a very sharp blade, on reassembly the cut is barely noticeable and the adhesive is left uncompromised. This doesn't work where labels cover screws, of course.

It dates to the late 1980s. And that’s what I still use whenever I’m away from my normal workbench. Before stocks of this Antex iron ran out, I bought another one just in case…
    I have a Chinese made soldering station that I now use on my workbench. It’s fine for normal PCB and connector tasks, but if I need to solder or desolder any large joints, it’s the Antex TCS that does the job.

    Having the capability to go to high temperatures is definitely nice but as you mention can be really hard on the tip over time.
    I think a good solution is to have a more sensible standard temperature and then have some kind of easy to use "high-power" mode, especially if it the element has decent heat output (say 40+W). The IronOS firmware for Pinecil/TS100/MHP30/TS80 for example has a single-button 450C boost mode for example and I can definitely attest that it works great on my Pinecil (V1) when you have something that needs a bit of extra help.

    It is interesting that vaping devices with temperature stabilization actually use the same two terminals on the 510 connector to measure the temperature: knowing the thermal curve of wire resistance (in case of a homogenous coil) allows for finding out the temperature of the coil by measuring its resistance. This is why at some point they switched from nickel-chromium wire to alloys with higher thermal resistance dependence coefficient - like stainless steel and others.

    FYI the isolation on the screwdriver is not essentially aimed at avoiding you an electrical shock if you handle it by its metal part while it touch one live element, but protect you from making an accidental short circuit between 2 different live elements and getting blasted and severely burned in the process if the current and/or the voltage delivered by this short circuit is important, like when working in industrial machines panel command boxes, where you might have to act without cutting the main switches if you are an electrician.
    Where I live, by regulation, those boxes - well the recently installed ones - should only contain equipment that cannot be short circuited with such a tiny length of metal (IP2X standard).
    I've learned that just today from the instructor of one of those mandatory courses you need to take if you work in a place where anything electrical is done - not that it applies to me as a software engineer, but I started working in an electrical test labs environment recently (on electric vehicles charging stations firmware).

    These 20V Parkside tools are good value for money for light use but can be a little fragile. The first time I plugged my charger in it went pop and released the magic smoke, no problem on exchange in the shop and the replacement is still going. However the battery I use on the multitool isn't the most robust, I must have knocked it around one too many times and one of the blade terminals cracked inside the housing. I ended up soldering a link wire from the blade terminal to a solder pad on the board, there was just too much force on the terminals for a solder joint to survive on the crack itself.

    It'd be interesting to see a "joule thief" design, because the iron would not need to be voltage regulated. Could use a much larger range of supplies, and only need a little bit for a regulator.

    As for the isolation of the screwdriver shaft: It protects not only against a clumsy human to touch the potentially live shaft of your driver, but also against connecting it to other components or the case. You might hold or rest your hand on the metal case of your junction box while screwing down live wires and the plastic protects you from shorting that to the case. Best case you pop a fuse or the GFI and the power goes out, but there was probably a reason you didnt cut the power to the terminals in the first place. So its not a completely stupid standard.

    Using the comparator built in to the micro is a great way of providing a safety function. It can kill the power if the controller latches or the drive latches high,it takes the safety function away from the software. You an set it to also interrupt the MC so it can try to recover from the error. If you need a safety function its easier to do it in hardware than software, kill the fault then let the software recover if it can. Hardware is far easier to certifie than software.

    @foogod4237 2 роки тому +1

    This is actually really cool, and I might actually look into how to get ahold of one of these in the US.
    I think I might be inclined to, instead of having a fixed resistor or a trimmer pot, etc, actually add an external switch to allow switching between "high" (480-ish C) or "medium" (350-ish C) settings, which would probably cover most of my own needs pretty well (I do often want to solder things for which 450+ C would probably be just too hot, but it would be nice to have the option when working on things like (as you mentioned) automotive or house wiring type stuff)...
    And I think the reason it's got such a complicated switching design, and it's got a separate "power on indicator" line and "shutdown" line is that it's actually carefully designed so that if _any_ component fails in any way, the MCU will be able to detect it and prevent any possible configuration where such a fault would cause the iron to be live when it's not supposed to be. If either of the initial "voltage converter" transistors fails in the "on" state somehow, for example, it will be able to detect that they have turned on the iron even though it didn't tell them to, and the separate shutdown signal can be applied to halt everything even if the normal power control line doesn't work as normal due to component failures. By my reading, the only possible way for the iron to be hot when the MCU doesn't intend it to be is if the main switching MOSFET actually fails shorted somehow (which is hard to protect against). Anything short of that is detectable/preventable due to the design, though...

    The screwdriver insulated tip is not for your finger's safety, it's for when it's on top of one terminal, the body doesn't "touch" another terminal and connect them together.

It is mains powered and cost me £9 it comes with two tips, a stand and a small tub of flux.The tips are ready available from ebay/amazon for pennies. Its a 30w with the tip that's held in with a screw ( if you know what I mean) don't know what temp it gets to but it's fine for me and seems to do the job nicely for what I use it for. ( mainly repairing and building my own through hole circuit boards) anyway the main reason I'm messaging you is that I have had this iron now for about 2 years and no issues at all I have only put two tips in it over that time and believe me it's done a lot of work so far ( I do keep the tip very clean and well tinned after every use) sorry I'm digressing 🤣 . I last used this iron last Saturday it is now Friday ( 6 days later) and have just come into my shed (which is my little workshop) to grab a beer out of the fridge after what seems a very long week at work. ( beer fridge in the shed is essential 🍺🤣) and realised that I left the iron switched on, I thought well that's it that heating element must be burnt out by now and the tip completely cooked to death, but to my absolute surprise it was still hot and running but the tip looked a bit sorry for itself, anyway I re tinned the tip and gave it a quick clean and it's like I never left it switched on. For a very cheap iron I'm absolutely gob smacked that it's still running and as for the tip that's surprised me too. Sorry for the essay but I'm so surprised by this if it had of burnt out I would have just bought another one for less than a tenner who cares anyway 🤣 . I did mean to add that this iron is not temperature controlled, just wondering why it didn't burn out any ideas or have I just been lucky.

    The "trick" underpowered irons use by going extremely hot, can work for some applications, but I would caution against using it on small and especially SMD solder joints. Because upon initial contact, it can be hot enough to break down the adhesive securing the solder pads to the substrate/board. Meaning you risk detaching pads from the board. And if that pad is attached to a via straight underneath it, there might not be an available surface trace for you to attach a jumper wire to, and you're gonna have a really bad day.

    I wonder if it's running full-power at max temp for parts count reasons. As you pointed out, the board has space for a trimpot and in lieu of that, it just has a zero-ohm resistor. It also has an unpopulated pad for a second MOSFET. Could it be that at max power, the MOSFET is being pushed into saturation in the 'max power' config, requiring little power dissipation (enough to be handled by one device), whereas if the controller were adjusted to a lower temp, the MOSFET would slip into the linear region, which would increase power dissipation, requiring two MOSFETs to handle the load?

In my experience in a circuit like this the (by far) highest risk of failure is the Power MOSFET. These fail typically by shorting out drain and source, which means the soldering iron is fully powered and something else (probably the heating element) would need to suffer a painful death. In that case the ForceOff circuit does not help at all.
    Why spending so much effort in a ForceOff logic, but not investing in a second FET to cut of the current in case of failure? Or is there maybe any trick to command the battery switching off its supply current? Do you know how the soldering iron behaves if the FET is shorted?

    This looks like just the thing i could use in my garage. Well it would be if it wasnt for a crazy thing. I left my lovely old Weller tcp iron untended, the thermostat shorted & damaged the heater. Decades of soldering iron love was over i thought. But no, i found a replacement & the damaged one with a short in the heater works well enough on 12 volts dc 🙂 My Weller iron continues.

    Handy tools to have.VDE compliance causes issues !I still have my low voltage Ungar from the 80s .have gone through a few tips but .it still works .Ozone has started to attack the rubber strain reliefs but it keeps on working.They have pt 100/1000 as tiny as 1mmx.5mm as a tiny chip with 2 tiny wires on it .Amazing to see .8 should send you a photo of one .It was in a 1/4 inch stainless tube probe

    Modern SWD (and JTAG) programmers usually have a voltage sense input so they can automagically adapt to programming 5V, 3V3, 1V8 or whatever systems.
    That might be what's going on with the PRG1 header.

    That looks nice and is a decent price ino. I've been using my TS100 plugged into a m18 or 2 m12 batteries when I need to travel. There's 3d printed battery connectors that go nice with 3d printed stands that are nice, a plus so you can stay with your chosen ecosystem of tools

    When working outside on a vehicle even the faintest breeze will cool your iron.I have a really old 100W iron for those big terminals/connections, its got a massive copper tip.
