Feature: 1.High power free lead soldering station, prompt temperature recovery, apply to lower temperature welding or free lead soldering. 2. Temperature dominated by insert card, preventing temperature changing unexpectedly and unnecessarily. 3. Setting with error indicator; when tip temperature is lower than minimum warning range, or when errors occur to any elements (e.g.: heating element, PCB, etc.), the station will send error signal to remind worker to repair it. 4. Digital temperature correcting function. 5. Light portable handle which is excellent for long time using. 6. Automatic power off function. 7. Static eliminating design, stable tip to ground resistance, with 33V output heating element, ensuring the operator's safety and protecting the sensitive elements in the station. 8. Temperature display in Fahrenheit or centigrade. 9. Setting minimum temperature to effectively avoid welding hole or weak welding.
