Operating Instructions
1. Tip Installation
Ensure the unit is powered off and the pen is cool before installing or changing tips. Use the provided screwdriver and tweezers to securely fasten the wire-nib tip into the pen's connector. A loosely connected tip can lead to poor temperature performance.

2. Power On and Temperature Adjustment
Connect the power cord and turn on the unit. The LED display will show the current temperature. Use the adjustment knob to set the desired temperature between 250°C and 750°C (482°F to 1382°F). It takes approximately 1 to 2 minutes for the wire-nib pen to heat up completely. Wait for the tip to reach the set temperature before beginning your work.
