How To Make A Plasma Cutter From A Mig Welder
If you have a mig welder lying around and want to expand its capabilities, why not turn it into a plasma cutter? With a few modifications, you can transform your mig welder into a powerful tool for cutting through metal like butter. In this article, we will guide you through the process of making a plasma cutter from a mig welder, step by step.
Firstly, it’s important to understand the basic principle behind a plasma cutter. Unlike a traditional arc welder, a plasma cutter uses a concentrated jet of superheated ionized gas, or plasma, to cut through metal with precision and ease. By converting your mig welder into a plasma cutter, you will be able to achieve clean, accurate cuts in a fraction of the time.
The first step in making your plasma cutter is to gather the necessary materials. You will need a mig welder, a compressed air source, a cutting torch, and some additional accessories like hoses and fittings. It’s important to note that not all mig welders are suitable for conversion, so be sure to check the specifications of your welder before proceeding.
Once you have all the materials, you can start the modification process. This typically involves removing the wire feed assembly and replacing it with a cutting torch. You will also need to connect the compressed air source to the torch, as the plasma is created by passing the compressed air through an electric arc.
After the modifications are complete, you can test your newly created plasma cutter. Make sure to follow all the necessary safety precautions and wear appropriate protective gear. With the right settings and technique, you will be able to cut through metal with incredible precision and speed. So, why spend a fortune on a dedicated plasma cutter when you can repurpose your mig welder into one?
In conclusion, turning your mig welder into a plasma cutter is a cost-effective way to enhance its functionality. By following the step-by-step process outlined in this article, you can create a powerful tool for cutting through metal with ease. So, dust off that old mig welder and get ready to take your metalworking projects to the next level!

| Step 6 | Test the plasma cutter by turning on the power supply and pressing the trigger on the plasma cutter torch. Ensure that the plasma cutter is cutting properly and adjust the settings if needed. |
| Step 7 | Once you have confirmed that the plasma cutter is working correctly, you can start using it for your projects. Remember to always wear the appropriate safety gear and follow proper safety precautions when operating the plasma cutter. |
By following these steps, you can easily convert your MIG welder into a plasma cutter and enjoy the benefits of having two tools in one. This can save you money and provide you with greater versatility in your workshop. Happy welding and cutting!
What You Will Need
To make a plasma cutter from a MIG welder, you will need the following materials:
1. MIG Welder
You will need a MIG welder with a power output of at least 100 amps. This is necessary to generate the high temperatures required for plasma cutting.
2. Air Compressor
An air compressor is needed to provide the compressed air necessary for the plasma cutting process. Make sure it has enough capacity to supply the required air flow.
3. Plasma Cutting Torch
A plasma cutting torch is the main tool used for plasma cutting. It consists of a handle, a trigger, and a consumable nozzle. Make sure to choose a torch compatible with your MIG welder.
4. Consumables
You will also need a set of consumables for your plasma cutting torch. This includes nozzles, electrodes, and swirl rings. These consumables wear out over time and need to be replaced periodically.
5. Safety Gear
Safety should be a top priority when working with any cutting or welding equipment. Make sure to wear protective gear such as gloves, safety glasses, and a welding helmet to protect yourself from sparks and heat.
| Material | Quantity |
|---|---|
| MIG Welder | 1 |
| Air Compressor | 1 |
| Plasma Cutting Torch | 1 |
| Consumables | Various |
| Safety Gear | As required |
Step-by-Step Guide
Below is a step-by-step guide on how to make a plasma cutter from a MIG welder:
Step 1: Gather the necessary materials
Before you begin, make sure you have all the materials you will need for the project. This includes a MIG welder, a plasma cutter torch, safety goggles, gloves, and suitable scrap metal to practice on.
Step 2: Disconnect the MIG welding gun
Start by disconnecting the MIG welding gun from your MIG welder. You will be using the plasma cutter torch instead, so it’s important to remove the welding gun to avoid any accidental usage.
Step 3: Connect the plasma cutter torch
Next, connect the plasma cutter torch to the MIG welder. Make sure it is securely attached and that all connections are tight. This will ensure proper functionality and safety when using the plasma cutter.
Step 4: Adjust the settings
Now, adjust the settings on your MIG welder to accommodate the plasma cutter torch. Refer to the user manual or guide for your specific welder model to ensure you set the correct amperage and cutting speed for the best results.
Step 5: Prepare the metal
Clean and prepare the metal you will be cutting. Remove any rust, paint, or debris that may interfere with the cutting process. It is important to work on a clean and flat surface for optimal cutting results.
Step 6: Put on safety gear
Prior to turning on the welder, put on your safety goggles and gloves. Plasma cutting produces sparks and can release harmful fumes, so it’s crucial to protect your eyes and hands.
Step 7: Start cutting
With all the safety precautions in place, you can now start cutting the metal using the plasma cutter torch. Move the torch in a steady and controlled motion along the desired cutting line. Take your time and ensure you maintain a consistent distance between the torch and the metal.
Step 8: Practice and refine your technique
As with any new skill, practice makes perfect. Take time to practice cutting on scrap metal before moving on to more precise cutting tasks. This will allow you to refine your technique and familiarize yourself with the plasma cutter’s capabilities.
Step 9: Clean up and maintenance
Once you have finished cutting, make sure to clean up the workspace and properly store your equipment. It’s also essential to regularly maintain your plasma cutter and MIG welder to ensure their longevity and optimal performance.
Following these steps, you will be able to transform your MIG welder into a functioning plasma cutter. Remember to always prioritize safety and take the necessary precautions when working with power tools.
