What is a battery-powered soldering iron?

A battery-powered soldering iron is a handy and easy-to-use tool that costs almost the same as a good quality electric soldering gun*. Another handy feature of these tools is that many of them come with a low energy use LED light which is great for enhanced vision while soldering in dark places or to overcome shadows.

How many AA batteries does a cordless soldering iron use?

Cordless soldering irons that run on disposable AA batteries typically use a battery pack that requires 4 AA batteries. These batteries can provide up to 1 to 2 hours of uninterrupted service. A single set of 4 AA batteries often lasts longer than a rechargeable lithium-ion battery.

Can a soldering iron be used on heavy metal?

A soldering iron cannot be used for welding heavy or thick metals. Since welding requires melting the surface of two different metal pieces before joining them together, the soldering iron or station does not produce the necessary heat for this objective.

How do you Weld a resin cell with a soldering iron?

Put some solder on your iron, then put the soldering iron on the cell, then add a bunch more solder: Let it cool and then clean off the resin: You can test the strength of your weld by applying force with a knife on the edge of the solder.

How to add solder to a cell?

Before we can add solder to the cells, we need to remove the oxidised layer from the cells. I do this by scraping carefully with a knife. But the cell flat on the table and start scraping at the center of the contact point. Heat the soldering iron to 450 C (842 F). Less might also work, but this is the temperature that I used.
