Pico soldering iron WXPP MS 40 W, 12 V (hand piece without tips) for active-tip heating technology. Intelligent WX tool: An integrated PCB enables the tool to capture parameters and reproduce them when used with another station. Integrated motion sensor: Detects the mode the tool is in; when the tool is not moving or not in use, it goes into either stand-by or off mode (defined by the user). Most precise performance: Enables you to work on small and sensitive components precisely and easily. Accurate tip temperature: No temperature fluctuations and therefore no damage to components or workpieces. Patented tip-and-grip in one single unit: Enables extremely precise working and reduces pressure on the component, eliminating any risk of component damage. Tool-less tip change: The tip can be changed quickly, without using any additional tools, resulting in significant time and cost savings. Short distance from the tip to the handle: Enables easy handling even when working under a microscope. Patented boomerang grip for more ergonomics: Offers excellent hold and grip, allowing easy movements and control of the tool without slipping, even after long use. All Weller active tips have the Weller part number and logo engraved, making reordering easy and helping to prevent any counterfeit issues, guaranteeing high Weller quality.
