Tip Temp Accuracy: How Hot is Your Tip?

by Julie S. on May 29, 2015

Tip Temp AccuracyToo hot or too cold, your soldering tip can cause damage. Hot tips lead to trace lifting, circuit board defects and component damage. Cold tips lead to longer dwell times, poor heat transfer and poor quality solder connections. Maintaining an accurate temperature is the trick to top performance.

So, what’s the best way to measure your tip’s temp? You can use either a thermocouple for absolute temperature or a contact pyrometer for temperature stability. Or, you can test your tip both ways with the Weller WA2000 Soldering Analyzer.

The WA2000 also measures tip-to-ground resistance and millivolt potential. The accuracy of the type “K” thermocouple used in Weller products is a Special Limit of Error (SLE) with a range of (1.1° C / 1.9° F) or 0.4%, whichever is greater. With the WA2000, you can monitor active soldering. You can also measure temperature loading, excursions and heater response—and that’s just the tip of the iceberg.
