How to make a simple pencil welding machine at home with a blade practical invention.
Here’s a practical and fun way to turn everyday items like a pencil and a blade into a simple welding machine for small tasks or demonstrations!
DIY Pencil Welding Machine with a Blade
What You’ll Need:
1. A wooden pencil (thick graphite core is ideal).
2. A sharp blade (razor or utility knife).
3. Thick copper wires or jumper cables.
4. A car battery or a 12V DC power supply.
5. Welding rods.
6. Insulating tape.
7. Safety gloves and goggles.
Step by step for preparation.
Prepare the Pencil:
Sharpen both ends of the pencil to expose the graphite core.
Use the blade to carefully strip away some of the wood along the length of the pencil to expose more graphite. This will act as the heating element.
Prepare the Blade:
Cut the blade into two smaller pieces if necessary.
These will act as connectors to help control the electric current flow.
Connect the Wires:
Attach the copper wires to both ends of the pencil using the blade pieces as connectors. Wrap them securely with insulating tape to ensure a stable connection.
Connect to the Power Source:
Attach the other ends of the copper wires to a 12V DC power source (e.g., a car battery).
The graphite in the pencil will heat up due to electrical resistance, generating enough heat to melt metal.
Start Welding:
Place the welding rod near the heated graphite tip and touch the workpiece. The arc created by the current will allow you to weld small metal pieces together.
Tips for Better Results:
Use a soft-lead pencil (2B or softer), as it has a higher graphite content and better conductivity.
Keep the connections tight to minimize energy loss.
Take breaks to avoid overheating the setup.
Safety Precautions:
Wear proper protective gear (gloves, goggles, and a mask).
Ensure good ventilation to avoid inhaling fumes.
Avoid prolonged use to prevent damage to the power source or wires.
This creative hack is not only functional but also an excellent way to learn about electricity and resistance welding! Would you like more DIY inventions like this?
