The 2UUL SC81 SurGun is a cordless, electric glue / flux / solder‑paste dispenser designed especially for electronics repair work (mobile phones, PCBs, etc.). It automates glue or paste application, providing better control and reducing mess. 

 

Key Features & Specs

 

 

Automatic / Actuated Dispensing: It has an auto‑release pressure mechanism that stops excess glue from oozing when you stop dispensing. 

 

Multiple Pressure / Flow Modes: Three speed / pressure settings (high / medium / low) let you adjust the flow depending on how much paste or glue you need.
