1. The surface of the workpiece must be clean and dry to ensure good contact.
2. After choosing the color you need, fix the ground wire clamp column on the workpiece and turn on the power.
3. During operation, the engraving pen should be kept perpendicular to the workpiece, moving slowly, and there should be a proper gap between the pen tip and the workpiece, and the output should be adjusted to the size of the pattern and the lines are completely clear.
4. For electrical engraving on aluminum, please use a copper-core pen tip instead.
