This post is the second example of how to make a 110 volt temperature controlled soldering station. Please refer to the previous post for information on materials used, their costs and where they can be obtained. The steps for modifying the soldering iron are very similar to the previous post but a few things are different for this version.

The steps for making the controller are virtually the same. As a result, most of the details for the controller have been omitted in this post. The main difference is the addition of a green ground wire to the 4-pin female DIN socket. (more…)

This post shows how to build a do it yourself 110 volt soldering station. It is a step by step guide that shows how to convert a regular plug-in soldering iron into a temperature controlled unit.

It is an easy project that is inexpensive to make and requires only basic skills to build. It is made from off the shelf parts that can be obtained from online suppliers plus a few parts from a local hardware store. It is inexpensive to build plus it makes a shop tool that is on par with some commercially available units. (more…)

Here’s a quick and easy way to spot weld a thermocouple with a 12 volt car battery, a set of jumper cables, a claw hammer and a set of long nose pliers.

This makeshift method can be used if the thermocouple spot weld breaks off or even if you want to make a new thermocouple from wire. (more…)

This is a follow up post on the second version for how to modify a regular plug-in soldering iron to work with a digital temperature controller.

The goal is to find the right location for the thermocouple inside the soldering iron. Temperature readings can be affected by the smallest change in position. The location of the thermocouple is very sensitive. (more…)

This post shows how to add a K-type thermocouple to a 120 volt plug-in soldering iron for use with a PID temperature controller. This is a follow up to a previous post on the Soldering Iron PID Temperature Controller. Please see the previous post for more details on how to add a thermocouple to a plug-in soldering iron with a mica heating element. The method I used here was basically the same.

This second version has a few improvements. It uses a better soldering iron that gets hotter and heats up faster. The PID controller is able to work at higher temperatures than the previous version plus this version uses an SSR to switch the soldering iron on and off. The solid state relay has no mechanical parts to wear out plus it is capable of much more precise switching than a mechanical relay. (more…)

This is a do it yourself project for a digital temperature controlled soldering station. It is an easy project that requires only basic skills to build and it it is constructed entirely from off the shelf components available from online sources.

The unit uses a PID temperature controller, an SSR (Solid State Relay) and a transformer plus a metal enclosure case, a soldering stand and a few other parts. It is relatively inexpensive to build, plus it makes a pretty good shop tool. (more…)

This is a follow up to a previous post on a way to get temperature control for a plug-in soldering iron without a temperature sensor. Instead of using a sensor to control the temperature, this unit sends power to the soldering iron in precisely timed pulses in a way that mimics the timing of how a temperature controlled soldering station does.

Watching the LED of a high quality soldering station blink on and off while the soldering iron was maintaining stable temperature gave me the idea. It looked like it was going on and off with regularity in a rhythm. I thought, why not use a timer circuit to do something similar for a regular plug-in soldering iron? (more…)
