Agenda
★ Always wear safety glasses when soldering.★ Never solder a live circuit (one that is energized).★ Soldering irons come in models that use different wattages. Use the right size
soldering iron for your projects; too much heat can ruin your board or components.
★ Never place a hot soldering iron on your work surface: You could start a fire.★ Never, ever try to catch a hot soldering iron if you drop it. Let it fall, buy a
new one if you have to — just don’t grab it!★ Give any soldered surface a minute or two to cool down before you touch it.★ Never leave flammable items (such as paper) near your soldering iron.★ Be sure to unplug your soldering iron when you’re not using it.
Solder Safety
1. Not Enough Heat2. Too Much Heat3. Not enough solder4. Moving joint before solder solidifies5. Dirt or grease6. Carbon on tip of solder iron7. Wrong materials8. Failure to test the joint

Practice
Paper Clip Man
Practice soldering using paper clips. Start by soldering 2 paper clips together. Heat the paperclips up with the soldering iron first then add a small amount of solder. Then try to make a “Man” like the one shown below.
