YIHUA Anti-Static Soldering Station Series

Thank you for purchasing this soldering station. This product is specially designed for lead-free soldering. Please read the instructions carefully before use. After reading, please keep it for future reference.

Safety Rules

Use the machine, the following basic measures should abide, avoid electric shock or cause injury or damage caused by fires.

• You must use the original approval or recommendation of the parts, otherwise it will lead to serious consequences.
• Machine failure must be by professionals or the company designated personnel for repair.
• This product is a grounded three-wire plug, must be inserted within the three-hole grounded outlet. Do not change the plugs or use ungrounded three-adapter.
• When the hot air gun or soldering station is open, its temperature can reach 400°C. Do not use it near flammable gas or objects. The tube and the heat emitted are very hot and can burn the body. Do not touch the hot pipe and avoid direct injection to heat the human body.
• Before the hot air gun is turned on, please ensure it is in a safe environment; do not leave the job site.
• When the hot air gun opening, do not install the nozzle. The heat pipe and the nozzle must be cooling before installing another nozzle.
• After use, the machine needs to cool down before packing.
• Do not use a soldering iron to weld outside the work area. Do not use the iron to strike a table to clear residual flux, as this could seriously damage the iron.
• The machine welding will produce smoke, please ensure proper ventilation.

Warning!!!

• If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
• WARNING: This tool must be placed on its stand when not in use.
• Be careful when using the appliance in places where there are combustible materials; do not apply to the same place for a long time.
• Be aware that heat may be conducted to combustible materials that are out of sight; do not leave the appliance unattended when it is switched on.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

I. Tip Maintenance And Use

1. When the soldering iron is used for the first time, pay attention to the iron tip warming situation. Wait until the temperature just melts the tin wire, forming a layer of tin on the gold-plated iron tip, and then raise the temperature to the required level. Keep in mind that when working, the iron tip should always have a layer of tin for protection, to achieve optimal soldering function.
2. If an oxide layer forms on the surface of the iron tip, resulting in a false low temperature reading, making it unable to melt tin, the heating element is actually at a high temperature. In this situation, do not assume the temperature is rising again. Use a clean sponge to clear the oxides. If not cleared, turn off the power, let the soldering iron cool to room temperature, and then use No.0 sandpaper to gently clear the oxide. Repeat the operation from the first point.
3. Please pay more attention when placing the soldering iron back into the iron holder at high temperatures. Adjust the temperature button to below 250°C for standby use. If the standby time exceeds 20 minutes, please turn off the power. Otherwise, the soldering iron will be at a high temperature for a long time. This is because the accumulated temperature between the iron holder and the soldering iron can lead to accelerated aging of the heating element, formation of oxides on the soldering iron tip, directly weakening soldering, and in severe cases, melting the plastic of the connecting screw nut of the handle or causing a short circuit in the heating element.
4. If the tip is deformed or heavily eroded, replace it with a new one. (Note: Do not use a knife file to remove oxides from the soldering iron tip.)
5. When soldering, do not apply excessive pressure to the iron tip, as this will not change the thermal conductivity and may lead to damage to the iron tip.

IV. Replacement of the Soldering Iron's Tip and Soldering Iron Heating Core's Element

Soldering iron parts replacement

1. Unscrew nut No. 1, then remove steel tube No. 2, followed by removing the tip to be replaced.
2. For the replacement of the heating core's element, unscrew plastic cap No. 4, gently pull out the heating core, element No. 6, along with circuit board No. 7. Carefully remember the connection of spring No. 5.
3. The iron core from the circuit board welding, the replacement of the heating core, can be fitted well. Note the order of the iron core wire connection.
