The plasma cutting equipment that needs to be considered in the selection of plasma cutting machines has been widely used in automobiles, locomotives, pressure vessels, aerospace, nuclear industry, shipbuilding, steel structures and other industries! Due to its wide cutting range (can cut stainless steel, aluminum, copper, titanium, ordinary carbon steel and other non-ferrous metals), plasma cutting machines can completely replace oxygen acetylene cutting in some specific fields! 2kg-5kg Portable Electronic Scale 2Kg-5Kg Portable Electronic Scale,Electronic Scales,Hanging Scale,Digital Hook Weighing Scale Shanghai Liuyuan Trading Co. , Ltd. , https://www.ly-weighing.com
Do you purchase a cutting machine because of the need for frequent repairs and maintenance; whether you are working on a project that requires a high-performance cutting device; or you need a new piece of equipment to replace the one you are using now. Chainsaw? All of the above are enough for you to consider plasma cutting. At present, low-cost, more compact and portable machines are flooding the market, newer technologies have improved revenue, and are easier to operate, so it may be time for you to take the time and money to consider plasma cutting equipment. Plasma cutting is easy to use, excellent cutting performance, fast working speed and high efficiency.
1 What is plasma cutting technology?
Plasma cutting is a processing method that uses the heat of a high temperature plasma arc to locally melt (and evaporate) the metal at the workpiece cut and to remove the molten metal by high-speed plasma momentum to form a slit.
2 How do you compare plasma cutting and flame gas cutting?
Plasma cutting can only be effective on metals that can act as conductors – low carbon steels, aluminum and stainless steel are typical examples. When cutting low carbon steel, the operator will experience higher speed and deeper cutting results.
Flame gas cutting is cut by burning high temperatures or by oxidizing the metal. Therefore, the scope of its application has been limited to steels such as ferrous metals that can be treated using oxidation techniques. Metals such as aluminum and stainless steel form oxides that constrain further oxidation. This makes it impossible to process this type of material by conventional flame gas cutting. Plasma cutting is not resistant to oxidation, so it can effectively cut aluminum, steel, and other conductive metals.
And different types of gases can be used for plasma cutting, and most people currently use compressed air for plasma cutting. Air compressors are available in most cities. Therefore, plasma cutting does not require gases such as combustible gases and compressed oxygen as operating gases.
3 What can I do with plasma cutting?
Plasma cutting is the ideal way to cut steel and non-ferrous metals less than one inch thick. Flame gas cutting requires the operator to carefully control the speed of the cut to maintain oxidation. Plasma cutting is more flexible in this regard. Plasma cutting is excellent in some applications, such as cutting thin metal sheets, which is not possible with flame gas cutting. In addition, compared to mechanical cutting methods, plasma cutting is much faster and easier to perform non-linear cutting. Cutting metal materials such as aluminum, copper, and stainless steel is the strength of plasma cutting machines!
4 What plasma cutting can't be done, and flame gas cutting can do it?
Plasma cutting is more expensive than flame gas cutting when cutting thick plates. Flame gas cutting does not require the connection of power and compressed air, which is easier for some users to use. Flame gas cutting is faster than plasma cutting when cutting thicker parts of steel. However, the plasma cutting machine cuts the thin plate faster than the flame cutting, and the efficiency is higher and the effect is better!
5 How to choose when purchasing a plasma cutting machine?
Once you feel that plasma cutting is the right choice for you, here are some things to consider:
5.1 Determining the thickness of the metal you are most likely to cut The first factor to be determined is the thickness of the metal that is usually cut. Most plasma cutter power supplies are rated by cutting capacity and current rating. Therefore, if you usually cut thin metal, you should consider a low current plasma cutter. Also, although small machines cut a certain thickness of metal, the quality of the cut may not be guaranteed. On the contrary, you may get almost no cut-through and residual metal residue. Each machine will have the optimum cut thickness range set - make sure the settings are right for you. In general, plasma cutting machine selection must be multiplied by 60% based on the ultimate cutting thickness, which is the thickness of the normal cutting of this equipment (can guarantee the cutting effect). Of course, the thinner the cutting effect and the faster the speed, the thicker the cutting effect and cutting speed will be reduced.
5.2 Selecting the load continuation rate of the device If you are going to make long cuts or automatically set cuts, be sure to check the machine's workload continuation rate. The load continuation rate is simply the continuous working time before the equipment is operated until it is overheated and needs to be cooled. Workload continuation rates are usually determined as a percentage of 10 minutes. for example. A 100 amp current cycle of 60 amps means that you can continue cutting for 6 minutes at 100 amps of current output (100% for 10 minutes). The higher the workload cycle, the longer you can continue cutting.
6 Does this machine offer the option of starting at a high frequency?
Most plasma cutters have a pilot arc that uses high frequencies to direct current through the air. However, high frequencies can interfere with nearby electronic devices, including computers. Therefore, it can be quite advantageous to eliminate the startup of these high frequency potential problems.
7 Comparison of Loss and Lifetime There are various external parts on the plasma cutting torch that need to be replaced, which we usually call consumables. The machine you need to look for should be the one with the least amount of consumables. Less consumables mean cost savings.
