A plasma cutting machine is used to cut through electrically conductive materials by means of an accelerated jet of hot plasma. Plasma can be created by heating a gas or subjecting it to a strong electromagnetic field. Vicon has the industry’s best plasma cutting machines. Vicon knows that when investing in a machine of this magnitude, you want to make sure that it performs at the top of the industry.
How much power should your plasma cutting machine have?
This all depends on what you’re using it for. What types of metal will you be cutting and how thick will it be? One of the most important considerations for you to make when purchasing a plasma cutting machine is its power output. This determines how thick of a cut it will make, how long its duty cycle is and how quick and clean your cuts will be.
Power output is directly proportional to your input power. Some plasma cutting machines will work on standard 120V 15Amp outlets. Others require higher voltage and amps. Before making your selection, you need to know how much power you have in the location where you will be using your plasma cutting machine. You may need to hire an electrician to get you the necessary power and outlets.
Generally speaking, if you work with materials that are ¼” thick or less, then a 25 amp or less will suffice. If you need to cut metals up to 1/2” thick, then you’re going to want a unit with at least 40 amps. If you work with materials that are up to 1” thick, then you’ll need at least 80 amps.
What should your duty cycle be for your plasma cutting machine?
The duty cycle of a plasma cutting machine is the amount of time in an hour that the cutter can safely operate. This is generally expressed as a percentage and is determined by how much amperage the unit draws. Depending on how long you need to use the plasma cutting machine, duty cycle can be more or less important. It’s more important should you need to use it longer and less if the converse is true. Larger units with larger power supplies and prices tend to have a longer duty cycle. For more information, on specific duty cycles ask on of our sales representatives.
What are the consumables of plasma cutting machines?
Consumables are the part of a plasma cutting system that will wear out due to usage. The two parts of the plasma cutting machine that wear out most quickly are the electrode and the nozzle. The temperature of the plasma arc in the torch is roughly 25,000 degrees Fahrenheit. The nozzle is made of copper due to its superior properties of heat transfers. Copper melts at 1,100 degrees Fahrenheit. The compressed air is circulated within the nozzle in such a way as to create a heat barrier between the plasma and the copper to keep it from melting.
The electrode that does this contains hafnium. Hafnium is extremely efficient at emitting electrons. Eventually, the high temp of the torch will cause the hafnium to deteriorate. When this happens, the torch misfires and your cuts become less accurate. Handheld torches can be adjusted more easily to make up for this, but CNC consumables must be replaced more quickly to ensure continued accuracy.
The lifecycle and cost of consumables varies for each plasma cutting machine. You should consider consumables when purchasing your plasma cutting machine. You’ll want to know how much they cost to replace and factor consumables into the total cost of operating the machine.
