In the world of electronics repair, desoldering is often the real test of a tool’s capability—more demanding than soldering itself. That’s why Pro'sKit developed the SS-331N Desoldering Station, designed specifically to tackle common issues like incomplete desoldering, clogging, and operator fatigue. It’s also one of Pro'sKit’s most anticipated flagship products of the year.
🔧 Engineered for Power & Efficiency
At the heart of the SS-331N is a high-performance vacuum pump paired with an advanced solenoid valve, supported by two smart, efficiency-boosting features:
Adjustable Pump’s Pre-charge Function (0–5 seconds): Builds suction in advance, releasing it in a powerful burst to instantly remove stubborn solder.
Suction Delayed Function (0–5 seconds): Suction continues briefly even after the trigger is released, minimizing residue and reducing clogging risk.
Now with upgraded suction performance — continuous desoldering cycles increased from 90 to 200!
💡Pump Indicator
Stay in control with intuitive LED indicators:
White light –Pre-charge state
Green light –Desoldering in operation
Lights off – No operation
🌡️ Smart Design, Enhanced Productivity
3 New Preset Temperature Memory Keys: Instantly switch between frequently used temperatures—no more constant readjustments.
Upgraded Nozzle Size and Mass: Larger and heavier tip with 150% more heat retention for instant solder melting and minimal temperature drop.
Upgrade Visible Plug-in Filter: Clearly visible contamination levels make replacement quick and intuitive.
🤲 All-New Ergonomic Flexible Handle
The desoldering gun handle features an ergonomic design with a grip angle under 90°, reducing hand fatigue during extended use. Built for professionals who need consistent, reliable performance.
⭐ A Milestone Innovation for Pro'sKit’s 35th Anniversary
The SS-331N represents Pro'sKit’s dedication to professional-grade repair tools — powerful, intuitive, and built to last.
Backed by 35 years of expertise, the SS-331N is a symbol of Pro'sKit’s commitment to innovation in soldering solutions. This year, it will be showcased at Computex, alongside other new releases, as Pro'sKit brings Taiwan’s world-class toolmaking to the global stage.
