Ensuring Safe, Repeatable Soldering and Rework through
Temperature Measurement By Luca Conte, Sales Manager — Southern Europe, Weller

In both cases, it is crucial that the actual working temperature ensures a safe, repeatable process. Weller® has developed pro-

fessional soldering technologies that use closed-loop temperature regulation to monitor the temper- ature of the tip through a high- quality platinum sensor. This au- tomatically adjusts the power to the silver core heating element according to the application, com- ponent and solder joint size. As the Weller heater design
continuously maintains the same physical material characteristics during its lifecycle, no calibra- tion is required. The platinum
professional control unit that controls soldering and rework tools must ensure

This compactly de- signed, battery-powered device can easily be shared between dif- ferent workstations and its auto off function extends battery life. It allows for high-precision meas- urements, with a counter (to re- place sensors, for example). This new device has another

Precise Temperature Measurement
Weller’s WCU (T0053450 - For all your workbench needs.
199) is a compact, standalone and high-precision temperature measurement device for quick, accurate temperature measure- ment. The WCU unit is strategi- cally designed for users that need to make measurements quickly and easily, while main-
purpose as the temperature can be measured by the built-in ther- mo cross or with a standard ex- ternal type K sensor. Its main function uses the three filaments (one of which is only mechanical) that form the probe. The solder- ing tip has to touch at the inter- section of the filaments and the real temperature can be meas- ured and shown in the middle of the screen. The two contacts that carry
out the reading are protected with heat-resistant and antistat- ic caps to avoid false readings caused by the proximity of the soldering iron’s resistance to the probes. There is a metal plate under them to simplify cleaning, and the probes are easily re- placeable. As an alternative or in addi- tion to the thermo cross, a type K
