Are there any safety issues related to using a soldering iron to solder copper or aluminum coils?

Using a soldering iron to solder copper or aluminum coils can pose safety risks. Copper and aluminum can react when joined, potentially leading to a galvanic corrosion. Additionally, the high heat from the soldering iron can cause the metal to expand or deform, especially if not handled properly. Always ensure proper ventilation to avoid inhaling fumes from the soldering process. Wear heat-resistant gloves and safety glasses to protect against burns and flying debris. Ensure the work area is clear of flammable materials to prevent fire hazards.
