A quick way to solder large diameter conductors
I will show you an easy and quick way to solder two different conductors using the example of a copper wire with a diameter of 2 mm, a copper plate, or an ordinary metal nail. The problem with soldering such conductors is the difficulty of uniformly heating the contact point. It is almost impossible to ensure high-quality soldering using a household soldering iron, so we will not use this tool. The method is based on the use of a simple burner made from cheap materials that can be purchased in regular stores.
To make a compact burner we will need:
- Cheap lighter with flint and wheel.
- Plastic gel pen refill.
- Syringe needle.
- Hot glue gun.
- Super glue.
- Baking soda, used in baking.
Preparing to assemble the burner
Disassemble the gel pen, remove the refill, remove the metal writing element from it and get rid of the ink. You should have a clean plastic tube in your hands. You can replace it with any plastic tube of the same diameter.
For convenience, I recommend bending the plastic tube at a right angle. Bring it to the flame of a lighter for a few seconds and gently bend it in the middle.
Take a lighter. Using pliers, remove the metal guard, remove the wheel, silicon and feed spring. Be careful not to damage the plastic gas lever. We will need it to control the burner fire.
Gas burner assembly
Take a regular syringe needle. Do not throw away the cap, as it will be useful when storing the burner. Using a hot glue gun, connect one end of the plastic tube to the needle. Check the reliability and tightness of the fastening.
To connect the opposite end of the tube and the lighter you will need baking soda and superglue. The tube must be secured to a plastic lever, which opens the gas supply valve. The tube must be fixed in such a way that the lever can move freely within the limits specified by the manufacturer to start and stop the gas supply. Gently sprinkle the mounting area with baking soda and apply superglue on top. Check the operation of the compact gas burner by pressing the gas supply valve and applying a spark to the sharp end of the needle.
The quick soldering tool is ready.
Examples of soldering two conductors
For high-quality soldering of the twisted copper cables, we will use solder, rosin with alcohol and a manufactured torch.
Quick soldering process:
- The twisting area must be cleaned and treated with a solution of rosin and alcohol.
- We screw a piece of solder, made in the form of a thin wire, onto the joint.
- We light a compact burner and bring the flame to the junction of the conductors.
- We wait for uniform heating of the material and complete melting of the solder.
- Let's wait until the solder cools down. To remove traces of soot, wipe the soldering area with a rag moistened with alcohol.
- Check the connection quality.
Combining copper plate with copper wire
We proceed in the same way. We fix the conductors in a position convenient for soldering. We treat the joint with a solution of rosin and alcohol. Place a small piece of solder as close to the copper wire as possible. We take a torch and heat the contact area until the solder completely melts. If necessary, add the required amount of fixing material.
Soldering of different metals
Let's try the method using a metal nail and a piece of copper wire as an example. We wrap the stripped copper cable around a metal nail. Treat with rosin and alcohol. We wind solder between the turns of copper wire. We bring the flame of the burner to the joint and heat the material until the solder completely melts. To remove traces of burning, use a rag soaked in alcohol.
