The new ST-80 Lithium-Ion Battery Soldering Device uses the advantages of modern battery technology and makes this soldering device an enduring companion wherever mobile soldering without power supply is required. The soldering unit is designed for soldering in electronics, electrical engineering or precision mechanics. Ideal for service technicians, but also for many applications, e.g. in the automotive sector, model making or in the DIY sector. The ST-80 impresses with its fast commissioning and short heat-up time. Especially the long working time distinguishes it clearly from previously available battery soldering devices. The ST-80 is quickly recharged with the included mains charger, and the lithium-ion technology also forgives not quite complete charging when things have to go particularly fast. An LED on the charger indicates the charging status of the ST-80. The ST-80 is equipped with an inserted soldering tip. This means that the tip can be quickly replaced with a new soldering tip or one with a different tip shape if necessary. The soldering unit heats only as long as the On / Off switch is pressed. This increases safety because the device switches off automatically.Secondly, unnecessary heating is avoided, which extends the working time and increases the service life of the soldering tip. The very short heating-up time nevertheless enables rapid work.
