SAFETY INSTRUCTIONS
1. Please use ground clamp, proper power supply and other accessories to ensure safe use.
2. When SQ-001 is used for the first time, it may slightly smoke due to heating of electric heating element, which is normal Phenomenon.
3. If SQ-001 is used continuously for more than 350 ° C for 40 minutes, the handle temperature of soldering iron will reach 50°C~60°C.
4. When SQ-001 temperature rises, do not contact the iron head to avoid scalding.
5. When SQ-001 is powered on, the iron head cannot be replaced.
