ATTEN ST-100 Soldering Station

ATTEN ST-100 is a professional 100W digital soldering station designed for electronics assembly, PCB/PCBA soldering, repair, maintenance, training and general production applications.

The ST-100 uses a 100W silver-alloy heater (HS-3100) designed for fast thermal conductivity and temperature recovery. Its operating temperature range is 150°C to 480°C, with specified temperature stability of ±2°C under still-air, no-load conditions.

The station features an LCD display and provides three shortcut temperature settings, allowing frequently used soldering temperatures to be stored and selected quickly. It also supports temperature locking and MCU-controlled temperature calibration.

Smart standby and automatic shutdown functions can be adjusted from 1 to 120 minutes, helping reduce unnecessary heater operation and extend equipment life.
