Making a good solder joint on a coil or switch lug
Steps
- Clear old solder from the lug with a solder sucker or desoldering wick.
- Wrap or crimp the wire firmly through the lug so it holds before soldering, with no stray strands.
- Heat the joint and feed solder until it flows smoothly into the wire and lug.
- A good joint is smooth and shiny; a dull grey blob was not hot enough, so reheat it.
- Use only as much heat and solder as needed and keep the iron away from meltable parts.
