The Proskit SS-331B combines a 90W thermal unit and a 50W vacuum pump into a single digital station. The vacuum function removes molten solder in seconds — even on double-sided boards — while the microprocessor holds the selected temperature accurately throughout. An LCD screen displays the current temperature and operating functions at a glance.

The ergonomic pistol grip is designed for sustained use, and a Sleep Mode activates after 10 minutes of inactivity to protect the tip and conserve power. The station ships with a comprehensive set of accessories: three spare tips, three cleaning tools, and four filter sponges. It is certified CE and RoHS, and operates on 220–240V AC.
