    • Typical Use: Commonly used for tasks like reflow soldering, component removal, and circuit board repair.
  8. Soldering Tweezer:
    • Design: Soldering tweezers have a tweezer-like design with built-in heating elements at the tips.
    • Temperature Control: They often have adjustable temperature settings.
    • Typical Use: These tweezers are perfect for fine-pitch SMD soldering and other applications that require precision.
  9. Soldering Gun:
    • Design: Soldering guns are pistol-shaped and provide a high wattage output for quick soldering.
    • Temperature Control: They typically do not have adjustable temperature settings.
    • Typical Use: Soldering guns are useful for heavy-duty soldering tasks, such as plumbing, stained glass, and large electrical connections.
  10. Lead-Free Soldering Iron:
    • Design: These irons are specifically designed for use with lead-free solder, which requires higher temperatures.
    • Temperature Control: They often come with adjustable temperature settings to accommodate lead-free solder’s higher melting point.
    • Typical Use: Lead-free soldering is essential for compliance with environmental regulations, especially in electronics manufacturing.
  1. Micro Soldering Iron:
    • Design: Micro soldering irons are extremely small, lightweight, and precise, often resembling a pen with a fine tip.
    • Temperature Control: They typically offer adjustable temperature settings for intricate, small-scale soldering tasks.
    • Typical Use: Ideal for intricate work on miniaturized electronics, jewelry, watchmaking, and other fine detail applications.
  1. Cold Heat Soldering Iron:
    • Design: Cold heat soldering irons use a unique technology that heats up almost instantly and cools down quickly to minimize the risk of overheating components.
    • Temperature Control: They have limited temperature control, mainly controlled by the user’s contact with the workpiece.
    • Typical Use: These are suitable for quick, simple soldering tasks, but they may not be ideal for precision work.
  1. Pencil Soldering Iron:
    • Design: Pencil soldering irons are slim and lightweight, resembling a pencil in shape, with a narrow, fine tip.
    • Temperature Control: They often come with adjustable temperature settings for precision soldering.
    • Typical Use: Frequently used in fine electronics work, jewelry making, and other applications requiring a delicate touch.
  1. Heavy-Duty Soldering Iron:
    • Design: Heavy-duty soldering irons have a robust build with a higher wattage output, making them suitable for demanding soldering tasks.
    • Temperature Control: They may not have adjustable temperature settings and are designed for high-heat applications.
    • Typical Use: These irons are used for tasks like soldering thick wires, plumbing, and large metal joints.
  1. Desoldering Iron:
    • Design: Desoldering irons have a built-in vacuum or bulb for removing solder, making them ideal for rework and component removal.
    • Temperature Control: They offer adjustable temperature settings to suit the specific desoldering task.
    • Typical Use: Essential for removing and replacing components on printed circuit boards without damaging the PCB or components.
