Hot air gun Working Voltage: AC220-240V OR AC100-130V Frequency: 50Hz/60Hz Output Power: 800W Temperature Range: 100C~480C Temperature Stability:2 Air Flow: 150L/min (max) Soldering iron Working Voltage: AC220-240V OR AC100-130V Output Power: 80W Frequency: 50Hz/60Hz Temperature Range: 180C-500C Temperature Stability: 1C Soldering Iron : ESD design Heater Material : Ceramics How to use: 1. Clean the electronic components to be soldered. 2. Once iron reaches temperature (not too high, recommend 300-400). 3. Apply a little solder to the heated iron tip to prevent oxidation, then rub the iron tip to evenly extend the solder to the surface of the iron tip. 4. Start to solder
