Comparison Note
The Leister HOTJET S stands out as the most compact and lightweight hand tool in Leister's range, making it exceptionally suited for precision work, intricate detailing, and applications in confined spaces or with heat-sensitive materials. Its independent and stepless control of both temperature and airflow provides a high degree of versatility and accuracy. While other Leister models like the Triac ST and AT are robust and widely used for general plastic welding and processing, the HOTJET S is specifically engineered for tasks demanding superior maneuverability and fine control. Competing brands like BAK offer alternatives that often emphasize durability and suitability for heavy-duty industrial plastic welding projects.
