How To Use A Stick Welder As A Plasma Cutter
Have you ever found yourself in a situation where you needed a plasma cutter but didn’t have one? Maybe you were working on a project, and suddenly realized you needed to make some precise cuts in metal. Don’t worry – you can actually use a stick welder as a plasma cutter in a pinch!
But how does it work? Stick welders and plasma cutters may seem like they have completely different functions, but they actually operate on similar principles. Both tools use an electric arc to create heat, and then direct that heat to cut through metal. The main difference is that a stick welder focuses on creating a strong bond between two pieces of metal, while a plasma cutter melts and blows away the metal to create a precise cut.
So, how can you convert your stick welder into a plasma cutter? The process is actually quite simple. You will need a few additional accessories, such as a plasma torch and a high-frequency unit. The plasma torch is used to control and direct the plasma arc, while the high-frequency unit helps to start and maintain the arc. Once you have these accessories, you can attach them to your stick welder and start using it as a plasma cutter.
Tips for Using Stick Welder as Plasma Cutter
Using a stick welder as a plasma cutter can be a cost-effective solution for small cutting projects. However, it requires some techniques and precautions to get the best results. Here are some tips to help you use a stick welder as a plasma cutter:
Tips | Description |
---|---|
Choose the right electrode | Using the correct electrode is essential for successful cutting. Select an electrode that is compatible with your stick welder. |
Adjust the amperage | Set the amperage of your stick welder according to the thickness of the metal you plan to cut. Lower amperage is suitable for thinner materials, while higher amperage is required for thicker materials. |
Prepare the work area | Clear the cutting area of any flammable or combustible materials. Ensure that you have proper ventilation to prevent fumes and gases from accumulating. |
Wear appropriate safety gear | Always wear safety goggles, gloves, and protective clothing to protect yourself from sparks, UV radiation, and potential injuries. |

Cool down the metal | Allow the metal to cool down before touching or handling it. Hot metal can cause severe burns. |
Keep an eye on consumables | Check the condition of the electrodes and nozzles regularly. Replace any worn-out or damaged parts for optimal performance. |
Remember that using a stick welder as a plasma cutter may not provide the same precision and speed as a dedicated plasma cutter. It is more suitable for simple cutting tasks and occasional use. Always follow the manufacturer’s instructions and safety guidelines when using any welding or cutting equipment.
Understanding the Basics
Before we dive into using a stick welder as a plasma cutter, it’s important to understand the basics of both tools. Stick welding, also known as shielded metal arc welding (SMAW), is a process that uses an electric current to create an arc between a stick electrode and the base metal. This arc creates intense heat, which melts the electrode and the base metal, fusing them together to create a weld.
On the other hand, a plasma cutter is a machine that uses a high-velocity jet of ionized gas, known as plasma, to cut through electrically conductive materials. The plasma is created by passing an electric arc through a gas such as nitrogen or oxygen, causing it to reach a high temperature and become ionized.
Stick Welders
A stick welder is a versatile tool that can be used for various applications, including welding and even cutting. It consists of a power source, typically an AC or DC welder, and a hand-held electrode holder with a stick electrode inserted into it. The stick electrode is coated in a flux material, which helps to create a protective gas shield around the weld and remove impurities from the metal.
When using a stick welder as a plasma cutter, you need to modify the electrode holder and insert a specially designed cutting electrode. This electrode is designed to create a narrower and more focused arc, which is necessary for cutting through metal.
Using a Stick Welder as a Plasma Cutter
Now that you understand the basics of both tools, let’s explore how to use a stick welder as a plasma cutter. To do this, you will need to make some modifications to your stick welder.
Firstly, you will need to remove the stick electrode from the electrode holder and replace it with a cutting electrode. The cutting electrode is typically smaller in diameter and has a pointed tip, which creates a more concentrated arc. Make sure to securely fasten the cutting electrode in place to ensure a stable connection.
Next, you will need to adjust the settings on your stick welder. You will likely need to increase the amperage to provide enough power for the plasma cutting process. Consult your stick welder’s manual for specific guidance on adjusting the amperage.
Before you begin cutting, make sure to wear the appropriate safety gear, including welding gloves, a welding helmet with a tinted lens, and protective clothing. Safety should always be a top priority when working with any welding or cutting equipment.
Once you are ready, you can start the plasma cutting process. Simply position the cutting electrode against the metal you want to cut and strike an arc by tapping the electrode against the metal. This will create a high-temperature plasma stream that can easily cut through the metal.
Remember, using a stick welder as a plasma cutter may not provide the same precision and speed as a dedicated plasma cutter. However, it can be a handy alternative if you already have a stick welder and need to make occasional cuts on metal.
Safety Precautions to Consider
When using a stick welder as a plasma cutter, it is important to take certain safety precautions to ensure your well-being and the well-being of those around you. Follow these guidelines:
- Wear appropriate safety gear, including a welding mask, gloves, and a welding apron. This will protect you from flying sparks and hot metal.
- Ensure that your work area is well-ventilated. Plasma cutting can produce harmful fumes and smoke, so make sure there is adequate airflow to dissipate these gases.
- Keep a fire extinguisher nearby in case of any accidents or sparks igniting flammable materials.
- Always inspect your equipment for any visible damage or defects before using it. This includes checking the cables, clamps, and connections.
- Ensure that the workpiece is properly grounded to minimize the risk of electric shock.
- Never touch the electrode or workpiece with bare hands while the welder is in operation. Use insulated tools if you need to adjust anything during the process.
- Avoid welding near flammable materials or in an environment with combustible gases or liquids.
- Always follow the manufacturer’s instructions and guidelines for operating the stick welder and plasma cutting attachments.
- Keep a safe distance from other individuals in your work area to prevent accidental contact with the welding arc or plasma cutter.
- If you are a beginner, seek proper training and guidance from an experienced welder to ensure you understand the safety precautions and techniques.
