Loose corroded metal screw kit, laboratory heating research, kitchen baking tools, factory equipment maintenance 2. Welding Cars, trucks, aviation repairs, hydropower engineering repairs 3. Electrical appliances, motor control box maintenance, welding, etc. 4. Wire, circuit board repair and welding, IC board welding and repair, home field circuit welding How to Use: One: Gas filling 1. Fill with high-quality gas, make sure that the switch is turned off, and then inflate at 0FF. 2. Introduce the gas tank into the air hole and press down to inflate. 3. Gas filling can be completed in about 10 seconds. Wait a few minutes for the gas to stabilize before using it. 4. If there is a hissing sound in the tail after the gas is poured in, use the pen tip to slightly press the air port to eliminate it. Two: Ignition 1. Replace the soldering iron tip 2. Push the switch to ON and hear a hissing sound 3. Use an igniter or lighter to ignite near the joint 4. After ignition, burn for 3 seconds. When the open flame is extinguished, the soldering iron tip will continue to heat up 5. Adjust the size of the flame, towards the "+" direction is larger, towards "-" Small direction 6. The flame temperature of this product is as high as 1300℃ (the temperature of the soldering iron tip is 450℃). Pay attention to safety when using it. After using it, turn off the switch to the OFF position. 7. When using a gas soldering iron, please pay special attention to the operation until the flame is completely eliminated when the object inside the soldering iron turns red, and the flame size should not be large to extend the life of the soldering iron tip 8. The length of the flame is about 1.5~2.5 cm . Package List: 1 x Pen-Type Gas Soldering Iron1 x Soldering Iron Tip Note: 1. Replace the connector, please replace it after cooling down or replace it in advance.2. The soldering iron tip in use is hot, please do not touch it with your hands.3. The adjustment knob can control the gas output and temperature, usually in the middle position.4. After use, wait for it to cool down before storing, and don't store it in high temperature or direct sunlight.5. Children are not suitable for use, and need to be placed in a proper place when storing.6. Please use high‑quality canned gas for filling, keep away from the fire source when filling.7. Because of the gas, there is more or less slag, so it is necessary to clean the nozzle frequently.8. When cleaning, press the nozzle on the gas outlet of the gas tank to spray to achieve the cleaning effect.9. Avoid heavy falls.10. Do not try to disassemble or repair under any circumstances
