1. Compact mechanical design for easier soldering work. 2. Quality heater with extended working life. 3. Simple and easy to use for completing welding operations. 4. Rated for use with 0.8 ~ 1.2mm tin wire. 5. Operating voltage: 220VAC. How to use: 1. When using the soldering iron for the first time, warm it for a few minutes. Slight smoke is a normal phenomenon and will disappear within seconds. 2. Insert the tin wire into the designated opening, then pull the trigger in the direction indicated until the solder wire reaches the nozzle and begins to melt. 3. To stop or replace the tin wire, simply release the trigger and remove the wire. 4. To replace the heater, first remove the protective cover, disconnect the heater connection, then remove the iron tip to access and replace the heating core. Caution: 1. During operation, the soldering iron tip and nozzle can reach temperatures up to 400 degrees Celsius. Avoid contact to prevent burns. 2. When not in use, always place the soldering iron on the stand. 3. After use, turn off the power and allow the unit to cool before storing. HOW TO SOLDER: 1. Clean the parts to be joined. 2. Clean the soldering iron tip and apply a thin layer of solder to all surfaces of the tip (tinning). 3. Heat the component and joint area. Apply cored solder directly to the heated joint (not the tip) until the solder flows smoothly.
