Soldering Iron Tip 

Changing Soldering Tips

• Unplug Pro 32 before changing. 
• Loosen the tip setscrew. 
• Pull out the tip, replace with another one. 
• Tighten the screw.

Choosing Soldering Iron Tips  

Note: Choosing the right tips will help you to work more efficient 

Soldering Iron Tip Maintenance

• Before switching off, wipe the tip's soldering side with some solder. 
• Do not leave the tip in high temperature for long time, which may causeit bum out. 
• Do not push too hard while soldering, which will damage the tip. 
• Do not use rough material or files to clean the tip. 
• If the tip surface is oxidized and makes it hard to apply solder on it, you may use 600-800 grit sandpaper to wipe the tip with Ethanol or lsopropyl alcohol, heat up to 200°C and apply solder immdeiately to avoid it oxidize again. 
• Do not use Flux that contains high chlorine or acid, use only resin based flux. 

Soldering Iron Tip Lifespan

Soldering iron tips lifespan is related to its maintenance and use intensity.
