Detailed Answer
Metallurgy high-temp protection: 1. Select wide-temperature model (Lideral metallurgy version -50~80°C+); 2. Store in cool place when not working (duty room); 3. Avoid prolonged handheld in high-temp radiation zone (rotate during operation intervals); 4. Battery high-temp protection (Li-ion high-temp risk); 5. Housing heat-insulation design. Xingjia metallurgy models likewise.
| Selection | Wide-temperature version |
| Storage | Cool place |
| Battery | High-temp proof |
Note:Keep operation time in molten steel radiation zone within 15 minutes with rotation.
