The Weller® WP 120 High-Power Soldering Pencil offers twice the efficiency in a small, ergonomic pencil design. Thanks to the combination of a compact, powerful heating element and a replaceable soldering tip, the WP 120 soldering pencil guarantees dynamic performance at the lowest life cycle costs. The rapid heat transfer into the soldering tip is controlled by precise electronics. This enables the compact WP 120 to master even large and difficult solder joints, even in hard-to-reach places.
