The 1up Racing Premium Solder is a high-quality, lead-free solder that is designed for use in the electronics and racing industries. The 100g weight of the solder is enough to make several joints, depending on the size and number of wires being soldered. The ability of the solder to soak into the wire ensures that the joint is secure and electrically conductive. Additionally, the lead-free composition of the solder makes it a safer and more environmentally friendly option for users.
