We used a 19.5 V netbook supply which was far more than capable of delivering the 40 W the instruction leaflet claims for the iron at 19 V. We hadn’t ordered a power supply with our TS100, but you will doubtless be able to buy one if you don’t have one of the right power level and polarity to hand. The whole assembled unit weighs 30 g, or a shade over an ounce, and has a balance point almost at its centre. The assembled TS100 ironĪssembling the iron is simple enough, the element slots into the receptacle and an Allen screw is tightened to hold it in place. Meanwhile the element unit is about 105 mm (3.15″) long, with an exposed length to the end of the bit of about 70 mm (2.75″). At its rear is a barrel socket for the DC supply alongside a micro-USB socket for firmware and configuration, on its top are a small OLED display and a couple of buttons, and at its front is a receptacle for the element unit. The handle is a plastic wand containing the temperature control electronics about 100 mm (4″) long, and similar in girth to a chunky fountain pen. There was no power supply, you supply your own 12 to 24 V DC to power it. Nestled in foam were the iron handle, a single combined element and bit, and an envelope containing a short instruction leaflet and a click-seal bag with an Allen key and a spare screw to secure the bit. The iron arrived well-packaged in a smart cardboard container that was well up to the task of protecting it through international air mail. We parted with just below £50 (around $60) to place an order for a TS100, and waited for it to arrive so we could see what all the fuss was about. The Miniware TS100 is a relatively inexpensive temperature-controlled soldering iron from China that has made a stealthy entry to the market, and which some online commentators claim to be the equal of far more expensive professional-grade irons. You might believe that this adage represents a cast-iron rule, no iron could possibly combine all three to make a lightweight high-performance tool that won’t break the bank! And until fairly recently you’d have had a point, but perhaps there is now a contender that could achieve that impossible feat.
Pick any two of those attributes when you choose an iron, because you’ll never have all three. Temperature-controlled soldering irons can be cheap, lightweight, and good.
