Preparation: always keep the tip clean, be sure to liberally coat the bit with solder the first time the iron is turned on. Note: initial tin is made in order to prolong the life of the bit. Wet the provided sponge before using. Check that the solder wire is ready for use and properly extended from the case. Make sure that the bit fits comfortably and has proper contact with the inner element. How to weld: after turning on the iron, the bit will start to heat up and be ready for use when the solder wire starts to melt on contact. Start the weld by ensuring the melt weld makes a clean connection between the contacts you are trying to weld. Move the solder wire and iron away once enough solder is placed and clean all residual solder using the wet sponge. Always remember to unplug the iron from the mains and place it on the provided support while cooling enough to be safely stored. Grades: Wear safety and take necessary precautions to avoid injury or fire. The iron heats up quickly. Select a suitable temperature to operate at. Using the iron for long hours and at a high temperature can shorten the product's life. Be sure to connect only the iron when necessary and unplug it when not, in order to reduce the risk of injury and fire. Clean the soldering tip always so often to extend its life. Avoid using chemicals and abrasive surfaces, as this could damage the metal surface. Package Include: 1pc or 2pcs electric soldering iron heater.
