Arduino Uno Quick Start Manual page 21

For the soldering tutorial, you need the following things:
• A 25W–30W soldering iron with a tip (preferably 1/16-inch) and a soldering
stand.
• Standard 60/40 solder (rosin-core) spool for electronics work. It should
have a 0.031-inch diameter.
• A sponge.
You can find these things in every electronics store, and many have soldering
kits for beginners that contain some useful additional tools. Take a look at
Adafruit (product ID 136) or Maker Shed (search for Soldering Starter Kit).
