SDG #288 Atten USB GT-2010 Temperature Controlled Soldering Iron

The Atten GT-2010 is a USB powered, temperature controlled soldering iron built around an inline controller that draws 5V at up to 2.1A, giving just 10W of heating power. At roughly £35 delivered it initially looks like good value, but the review makes clear that the real cost sits in the Weller style cartridges, which use a 3.5mm jack and a surprisingly heavy machined body. They are only marginally cheaper than premium JBC or Metcal cartridges, so a usable two tip setup pushes the total closer to £50, or £65 once the optional stand is added.

The handpiece itself is praised for being feather light and comparable in size to a JBC T245, with a decent strain relief and a clever tip cover that doubles as a hot cartridge removal tool. The controller offers three presets, single degree and 10 degree adjustment steps, a power bar graph, a 10 minute sleep timeout and user calibration. Opening it up reveals a straightforward design: an STM32 microcontroller, a segment LCD driver, a low drift op amp for the thermocouple and a single P channel MOSFET switching the element.

Temperature accuracy measured out around 10 degrees low, which is acceptable for this class of tool, though heat up is slow and the controller sits at full power for a long time. One of the two extra cartridges purchased arrived dead, showing roughly 500k across the element instead of the expected 2.3 to 2.5 ohms. The verdict is blunt: more capable USB C irons and cheap mains soldering stations both offer better performance per pound, leaving this one hard to recommend outside novelty or portability.
