Definition

1. Noun:
   • A tool used for soldering: A "soldering-iron" is a hand-held tool with a heated metal tip, used to melt solder (a fusible metal alloy) to join two metal surfaces together, typically in electronics or metalwork.

Usage Examples

• Noun:
  • He used a soldering-iron to connect the wires on the circuit board. (A tool with a heated tip for melting solder.)
  • The technician heated the soldering-iron before applying it to the joint. (Preparing the tool for use.)

Advanced Usage

• "to heat a soldering-iron": to raise the temperature of the tool's tip to the necessary level for melting solder.

  • Always heat the soldering-iron in a stand to avoid burns. (Proper handling for safety.)

• "to tin a soldering-iron": to coat the tip of the tool with a thin layer of solder before use, to improve heat transfer and prevent oxidation.

  • Before soldering, you should tin the soldering-iron by applying a small amount of solder to the tip. (A preparatory step in the soldering process.)

Variants and Related Words

• Solder (n): a metal alloy with a low melting point, used to join metal surfaces.

  • The solder melted quickly when touched by the hot soldering-iron. (The material used in the process.)

• Soldering (n): the act or process of joining metal parts using a soldering-iron and solder.

  • Soldering requires precision and a steady hand. (The technique itself.)

Synonyms

• Soldering tool: a general term for any device used in soldering.
• Iron: a shortened, informal term for a soldering-iron (e.g., "Pass me the iron.").
