FAQ

How thick can a plasma cutter cut aluminum?

Plasma cutters can cut aluminum up to several inches thick, depending on the power of the plasma cutter and the amperage setting used. Generally, a plasma cutter can cut aluminum up to about 1 inch thick with a good level of precision, and up to 2 inches thick if a more rough cut is acceptable. However, it's important to note that the thickness of the aluminum being cut will also depend on other factors such as the type and quality of the plasma cutter, the type of gas being used, and the skill of the operator.

Why wont my plasma cutter cut aluminum?

There could be several reasons why your plasma cutter is not cutting aluminum properly. Here are a few possible reasons:

1. Incorrect amperage: Aluminum requires a different amperage setting than other metals. If the amperage is too low, the plasma cutter won't be able to cut through the metal. Make sure you are using the correct amperage setting for the thickness of aluminum you are cutting.
2. Dirty or contaminated material: If the aluminum is dirty or contaminated with oil, grease, or other debris, the plasma cutter may not be able to cut through it. Clean the material thoroughly before attempting to cut.
3. Incorrect cutting speed: Aluminum requires a slower cutting speed than other metals. If you are moving the torch too quickly, the plasma cutter won't be able to maintain the arc and the cut will be incomplete. Slow down the cutting speed and ensure that the arc is maintained throughout the cut.
4. Incorrect cutting tip: The cutting tip used for aluminum should be different than the one used for other metals. Make sure you are using the correct tip for aluminum cutting.
5. Insufficient air pressure: Plasma cutters require a high volume of compressed air to operate properly. If the air pressure is too low, the plasma cutter won't be able to generate the necessary heat to cut through the aluminum. Make sure the air pressure is set to the recommended level for your plasma cutter.

If none of these solutions work, it may be a good idea to consult the user manual or contact the manufacturer for further troubleshooting.

How many amps does it take to cut aluminum with plasma?

The amperage required to cut aluminum with plasma can vary depending on the thickness of the material and the type of plasma cutter being used. As a general rule of thumb, a plasma cutter with a minimum output of 40 amps should be able to cut aluminum up to 1/4 inch thick. Thicker aluminum may require a higher amperage setting, such as 50-60 amps or more. It is important to consult the user manual for your specific plasma cutter to determine the recommended amperage setting for cutting aluminum.

What gas is used for plasma cutting aluminum?

Typically, compressed air is used as the plasma gas for cutting aluminum. However, some plasma cutters may also use a mixture of gases, such as nitrogen and hydrogen, to cut aluminum. The specific gas mixture used can depend on factors such as the thickness of the aluminum being cut and the type of plasma cutter being used. It's important to consult the manufacturer's instructions for the plasma cutter being used to determine the appropriate gas or gas mixture to use for cutting aluminum.

Plasma Cutting Aluminum hazards
