How to use

To begin, connect the soldering iron to a compatible power source using the provided USB-C cable. Once powered, use the physical buttons to select your desired temperature or choose from the pre-saved profiles. The device will heat up rapidly to the target temperature. When finished, place the iron on the included stand to trigger the automatic sleep mode, which preserves the tip and saves energy. Always ensure the device is grounded when working with sensitive static-prone components.

What to consider before purchase

• Ensure your power supply supports the required voltage and wattage for 100W operation.
• Check if the included tip shapes are suitable for your specific soldering tasks.
• Consider the need for a stable workspace or a portable power bank for field use.

Usage recommendations: Always use the provided stand to activate the inductive sleep mode when the iron is not in active use to extend the lifespan of the heating element and tips.
