How To Make Soldering Iron With 9v Battery

There is no thermal protection in the Dewalt batteries so an excess of current can heat them up.

How to make soldering iron with 9v battery. Before soldering scratch the top and bottom sides of the cell with sand paper to remove the oxide layer which will help solder to stick to. Solder doesnt harden instantly and if you immediately stop holding the wire itll just drop off - possibly spraying little globs of molten solder around as it does so. Making an electric soldering iron with your own hands is a fairly simple procedure that many masters will not cause any difficulties and.

It is very useful tool. Remove the soldering iron. Roughen up Battery Terminals.

Using the same process do the same on the other side of the battery holder. I thought of a bunch of projects from breadboarding to BEAM robotics to Arduino where a 9V battery clip with a built-in power switch could come in handy. If playback doesnt begin shortly try restarting your device.

Talc powder for electrically insulating mass. Made my own hammerhead tip for a cheepie 40W RS soldering iron from a nut and bolt with the same thread as the normal tip uses. Place the tip of the soldering iron on one side of the joint then place the solder on the OPPOSITE side of the joint.

Use some more of that silicone to anchor the wires in the hole after you know everything works. When no plug is present in the DC Jack the CONNECT SLEEVE terminals are internally connected or shorted. The RED wire is connected to the CONNECT terminal of the DC Jack.

You will rest the solder on the 2 exposed wires you wish to connect. Assemble the parts and apply flux to the surfaces to be soldered. Current batteries are made of alloys on which soldering is very poorly held.
