Weller WESD51 Digital Soldering Station

Weller WSD51 Set is a single channel digital temperature controlled soldering station with a power of 80 watts. The programming of the PUD51i power unit included in the kit is carried out using the buttons located on the front panel of the station.

The Weller WSD51 Set digital soldering station is recommended for lead-free soldering. Equipped with microprocessor control it has the ability to connect a calibrator both for reading settings and for recalibration and software updates.

The antistatic design of the housing contributes to an increase in the level of protection against the formation of ESD (electrostatic discharge), applicable for installation and dismantling works with BSEC components. The grounding plug for the Weller power block is located on the front panel.

Soldering Base

The soldering base itself is made of sturdy and reliable plastic, which prevents accumulating electrostatic charges. It has a simple and convenient design, which does not require a lot of space. On the front side, it has an LED display. It shows what temperature the unit has to provide. Moreover, it allows users to adjust the switch between Celsius and Fahrenheit depending on personal preference.

The power cord goes from the backside while the soldering pencil cord goes from the front. It can be easily detached and switched with another soldering pencil and iron tip. It means that if something does not work, you will not need to unscrew the soldering base and do complicated repairing manipulations.

The bottom part is equipped with four rubber feet. They help to keep the unit on the working surface during the whole soldering process, without sliding. 

Soldering Pencil

Soldering pencils from Weller are very convenient. In the place where you grab it soldering, it has a foam coating. It comfortably fits into fingers and does not tire them a lot during long working sessions. The power chord is made of heat resistant materials. 

Together with the soldering station, customers receive a PES51 iron tip. It is made of stainless steel with a nichrome coating. It provides a fast heat response and the possibility to control the temperature at needed values. The iron tip can be easily replaced if you need one of another type. However, it is necessary to mention that only iron tips from Weller are compatible with this soldering pencil and station. Soldering tips from other manufacturers may not provide the proper quality of soldering and proper heating. 

Cleaner Base & Holder

Another part of the WESD51 station is very important for convenient soldering. During work sessions, you always need to have a place where to put a hot soldering iron tip. The holder is made of steel, which is heat resistant. Moreover, you will not need to worry about drops of flux, as they will not stain the working surface. 

Cleaning is an undeniable part of the soldering process. Iron tips have to be without oxidation and ready for soldering. The front part has a section where you put wet sponges. With simple rubbing against it, users can clean tips. Due to reliable rubber pads, the customer is able to perform cleaning with just one hand, without holding the cleaning base with another one. 


Temperature control is important in the soldering process. With Weller WESD51, you can adjust it in Celsius and Fahrenheit, within the range of 350F to 850F. The LED display helps to always know what the temperature is even with poor light in the room. 

During soldering temperature of the iron tip always changes as it interacts with various metals. For more precise work, this device allows users to lock the temperature. It will constantly maintain the same level. 


This wonderful digital soldering station requires just 120VAC to provide a nice soldering experience. In case you need a model with 240VAC, you should consider WESD51D. Alternatively, those who have 220V at home, just need to connect the unit through transformation. In such a way, the soldering unit will work properly. 

In case you work on different projects, when you need to leave the soldering pencil aside, it is not a problem to forget about that with WESD51. After some period of inactivity, it will automatically shut down. It helps to prolong the life expectancy of the device and prevent overheating accidents.

  1. The Weller WESD51 can take a beating as you’re able to work with it for a very long time. The iron has a non-burnable silicon rubber cord which makes things safer. Other models don’t have this and there’s a chance you can burn the cord.
