FNIRSI SAG-55 Intelligent 550W Hot Air Gun

The FNIRSI SAG-55 is an intelligent 550W hot air rework station engineered for precision SMD soldering and component repair on densely packed drone electronics. It serves as a crucial bench tool for desoldering blown ESC MOSFETs, replacing damaged flight controller gyros, or reflowing delicate surface-mount connectors without scorching adjacent PCB traces. This listing is for the PRO variant.

Key features

• 550W heating output: Delivers rapid warm-up and stable temperatures, essential for combating the thermal mass of heavy-copper multi-layer FPV boards.

• Intelligent temperature control: Maintains a consistent heat profile to prevent thermal shock to sensitive VTX components and microcontrollers.

• Broad application: Capable of handling intricate microscopic desoldering work as well as heavy-duty heat-shrinking on thick battery leads.
