Now, how do you use a plasma cutter? By using the arc. To kick-start a plasma cutter’s arc, gently approach the torch to the workpiece. This guarantees the initiation of the plasma arc, initiating the cutting process. The torch’s proximity to the workpiece is critical for triggering the required plasma reaction. Proper positioning enables the plasma’s intense heat to melt and vaporize the metal, facilitating accurate and efficient cutting. Bringing the torch near the workpiece allows you to leverage the plasma cutter’s power and attain the desired outcomes.
- Press the trigger to initiate the arc
To start plasma cutting, just press the trigger to ignite the arc. This triggers a sequence in the cutter, where the high-frequency electric current flows through the torch into the electrode. The electrode, surrounded by a gas mix of nitrogen, oxygen, and argon, conducts the current. As the current passes through, it heats the gas, turning it into plasma. This rapid plasma is then expelled from the torch, allowing precise and effortless cutting across various materials.
3. Cutting techniques

When operating a plasma cutter, stick to the assigned cutting path. This method guarantees accurate and precise results in shaping or patterning. Adhering to the designated path not only prevents mistakes but also enhances safety by preventing the cutter from straying and causing harm to materials or oneself. It’s a key step to ensure the final product aligns with the necessary specifications. Hence, it’s vital to be attentive and scrupulously stick to the assigned cutting path when utilizing a plasma cutter.
- Adjust torch level to maintain a perfect cutting distance
When using a plasma cutter, ensure optimal results by employing correct cutting techniques. Adjust the torch level to maintain an ideal cutting distance – the space between the plasma torch and the material. Avoid inefficiency by keeping the torch neither too far nor too close; the former may impede the cutting process, while the latter can cause excessive heat, potentially damaging the material. By fine-tuning the torch level for the perfect cutting distance, users can achieve clean, precise, and efficient cuts with their plasma cutters.
- Shut down the plasma cutter after completing the cut
Turn off the plasma cutter once you finish cutting. This saves energy and enhances workspace safety by minimizing the risk of accidental fires or injuries from hot metal. It also extends the equipment’s lifespan by preventing unnecessary wear and tear. So if you want to use your plasma cutter for a really long time, then I suggest you turn it off when you are not using it.
