Workbench Skills Part 9: soldering — your first joint

// WHAT YOU WILL LEARN

Heat the pad and the leg together (≈ 1 s), feed solder into the joint (not the iron), solder off, then iron off: a shiny little cone = good, a ball = cold joint.

// LESSON NOTES

Your first solder joint in 3 seconds 🔥🔩

🌡️ Iron at about 350 °C (660 °F), clean shiny tip.
1️⃣ HEAT: touch the PAD and the LEG together — about 1 second.
2️⃣ FEED: push the solder into the joint (the side away from the iron), NOT onto the iron. The hot parts melt it, so it flows round the leg.
3️⃣ Pull the solder away first…
4️⃣ …then the iron. Don't move it while it sets.

✅ Good joint: a shiny little cone / volcano hugging the leg.
❌ Bad joint: a round ball sitting on top = a cold joint (the pad wasn't hot).
🧼 Use a fan for the fumes, put the iron back in its stand and wash your hands after.
