How To Make A Powerful Soldering Iron From Transformer

Assuming your requirements are not excessively light or heavy ideally a transformer suitable for use without modification in a resistance soldering power unit should have a line voltage either 110VAC or 220VAC primary winding a secondary voltage of around 6 VAC a secondary current rating of 20 to 50 amps or more and a rating of 100VA volt-ampere minimum with 250VA.

How to make a powerful soldering iron from transformer. An RSU can get very hot very fast and then it cools down fairly quick too. In this Instructables we are gonna make a 25 W soldering Iron. If you liked the Metal Melter you saw in my previous project heres how you can make your own.

You can use hot glue to fix switch and wire. 120VAC to 19-265V stepdown transformer radioshack x 1. Ad Compare a Huge Selection of Parts.

In this project youll learn step by step how to modify a microwave oven transformer into a high-current device that can pump out 800 amps of electrical current which is enough amperage to melt metal. You have a transformer capable of converting alternative currently at 110V into a lower voltage and a higher amperage to generate heat. This soldering iron will make even an absolute beginner.
