Help on soldering

---

-Use a good soldering iron with fine pencil tip. Radio-Shack irons are good and reliable.

-It is important to have aclean tip. Do not use very abrasive surfaces to clean / polish the soldering iron tip. if th etip looks bent or damaged, it is worth investing in a new tip.

-Please take all precautions while using soldering irons.

Solder on a fire resistant surface. Homosote, or dry wall are good .
Never leave your iron plugged in and unattended.
Do not overload a wall outlet with too many electric appliances.
Never set your hot iron down on anything other than an iron stand.
Replace the cord of your iron if it becomes worn or gets burnt.
To prevent burning your fingers, use needle nose pliers or heat resistant gloves to hold small pieces.
Never cut off a grounding prong on an iron plug to make it fit an ungrounded receptacle.
