What amp does a plasma cutter use?

For 3/8” cut, 40 amps works out well for most brands of plasma cutters. For ½” cut, 50 amps works out well, etc.

How much power does a plasma cutter need?

Generally, you will need to get something that is between three to five kilowatts. You might need a little more if you are planning on running an air compressor at the same time.

What size breaker do I need for a plasma cutter?

Usually 8 for 40 amps and 6 for 60 amps. I have the same Plasma Cutter you will really like it. that plasma will make you furious.

How thick will a 20 amp plasma cutter cut?

This plasma cutter is a precision machine designed for thin metals. It has a precise 0.65mm cutting tip to reduce slag so you can spend less time prepping the metal and get right to welding. You'll be able to quickly cut through metal up to 1/8-inch thick while plugging into a standard 110V wall outlet.

What current does plasma arc cutting use?

The power source required for the plasma arc process must have a drooping characteristic and a high voltage. Although the operating voltage to sustain the plasma is typically 50 to 60V, the open circuit voltage needed to initiate the arc can be up to 400V DC.

Setting the Correct Air Pressure and Amperage for your Plasma Cutter

Can I run a plasma cutter off a generator?

Spectrum plasma cutters feature special circuitry that enables them to achieve full cutting power and maintain a steady cutting arc when connected to generator power," said Brian Schmidt, product manager, Miller Electric.

What voltage do plasma cutters use?

Primary power

Several 30-amp plasma cutters, such as the Spectrum® 375 X-TREME™, operate using 120- or 240-volt power. If your input circuit has a 30-amp breaker, you even get equal cutting capacity at both voltages (with a 20-amp breaker, cutting capacity drops by 20 percent).

How thick will a 40 amp plasma cutter cut?

The 40D achieves a maximum cutting thickness of 13 mm and average Quality cuts up to 10 mm.

How thick of steel can a 50 amp plasma cutter cut?

Designed for portable repair work and small business project use, CUT-50 Plasma Cutter cuts a thickness of 3/4 in., and the max severance thickness is 1.0 in. Type: DC Air Plasma Cutter. Supply Power: 110-Volt/230-Volt/60Hz/1-Phase. Rated Input Current: AC 110-Volt/35.7 Amp, 230-Volt/27.1 Amp.

How thick can a 100 amp plasma cutter cut?

The Pioneer Plasma Cut 100 Amp plasma cutter is designed for tough heavy duty plasma cutting applications with a max cutting thickness of 30mm and quality cutting thickness of 20mm.

What size breaker do I need for a welder?

The circuit breaker that is most often used on welder installations is a double pole 60 amp size (in which case the feeder conductors must be sized accordingly) although the 50 amp size is usually more than adequate to serve the light-duty work for which most workshop units are used.

Is it expensive to run a plasma cutter?

Low Operating Costs

CNC Plasma cutters tend to cost around $15/hour to maintain. CNC Lasers are just slightly higher at $20/hour. And CNC waterjets usually come in at the most expensive – $30/hour.

Are plasma cutters expensive to run?

While it's cheaper per cut than Oxy-fuel, plasma cutting can still incur significant costs. Electrodes can be expensive to source and replace if the machine breaks down. Likewise, you may have to pay for a specialist gas supplier.

Can a plasma cutter cut rusty metal?

Plasma can cut any electrically conductive metal including stainless steel, mild steel, aluminum and more, without pre-heating. Plasma is also great at cutting painted, dirty or even rusted metal.

How thick will a 45 amp plasma cutter cut?

This is the new digitally controlled 20-55 amps Plasma Cutter Machine with advanced inverter technology and high cutting performance. Designed for portable repair work and small business project use, the CUT-45M Air Plasma Cutter cuts a thickness of 2/5 in. with the max severance thickness at 3/4 in.

How deep will a plasma cutter cut?

Plasma cutters are used to perform cutting and gouging operations, with the average hand-held system capable of cutting a maximum metal thickness of about 1 inch.

Where are Hobart plasma cutters made?

Hobart machines are American-made in Appleton, Wisconsin. The Airforce 27i plasma cutter is also CSA Certified. This machine features an ergonomic torch design and 12-foot leads on both the torch and the ground lead. The Hobart Airforce 27i features a built-in regulator, air filter and water separator.

Is a plasma cutter AC or DC?

The power supply is a constant current DC power source. The open circuit voltage is typically in the range of 240 to 400 VDC. The output current (amperage) of the power supply determines the speed and cut thickness capability of the system.

Do all plasma cutters need air compressor?

First, the arc heats the metal until it's semi-gaseous. Second, the plasma is forced by blasts of air to finish the cut. Therefore, all plasma cutters need an air compressor to generate enough air pressure for the task. If you buy a plasma cutter without a built-in source of air, you'll need a separate air compressor.

Can a plasma cutter Weld?

With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.

Can you run a plasma cutter off an inverter?

Plasma cutters can run off of 110V or 220V depending on the model you use. Some inverter units like our Versa-Cut 40 have the ability to sense the input voltage and run off either with a wall outlet adapter. Obviously the maximum output is lower when running on 110V than 220V on dual voltage input machines.
