Key Factors for Product Selection

1. Power rating determines heating speed and heat output: 560W models suit general electronic repair; 780W and above are recommended for large-area work and high-heat-dissipation substrate processing.
2. Adjustment modes fall into two categories: knob control offers intuitive, simple operation; digital display versions enable precise parameter monitoring and function memory.
3. Fan RPM directly affects airflow volume and hot air uniformity: 13,000 RPM meets regular demands, while speeds above 14,800 RPM deliver strong airflow for heavy tasks.
4. Power cord specifications relate to safety and service life. Thickened rubber cords compliant with new national standards are preferred for heavy-duty working environments.
