How Do You Solder An Electrical Connection?
Repairing electric and electronic devices often requires soldering. This is a skill which requires some practice, but with a steady hand and some patience, you can master it fairly quickly. Preparation. To solder a large connection like replacing a power cord to an appliance, use a higher wattage (100 W) soldering iron or gun. For smaller connections, or soldering to a printed circuit board use a 25 – 40 W Soldering iron. When soldering very small parts like components on circuit boards, be sure to use a fine tip iron. Use rosin core electrical solder. Acid core solder should never be used for electrical connections since the acid will corrode the connection. Be sure to work on a surface that won’t be damaged by heat. Be sure the parts to be connected are clean. Plug in the soldering iron and allow 5 minutes for it to heat up. Soldering guns don’t require this warm up time since they don’t heat up until you squeeze the trigger. Be sure to keep the iron away from wood, plastic, paper or
