How does a plasma cutter work?

Plasma_cuttingAll of us know what a plasma cutter is, but the working of a plasma cutter is not known to all. Here is a small description about the working of the best plasma cutter.

The working of plasma cutter is done by sending electric arc with the help of gas that passes through the restricted opening. The gas used can be nitrogen, shop air, oxygen, argon and so on. This increases the temperature of the gas up to a point where it enters the fourth state of matter. This state of matter is called as the plasma state. Thus, the name given is plasma cutter.

The metal which is being cut is a part of the circuit and hence the electrical conductivity of the plasma causes the arc to get transferred to the work. The constrained opening or the nozzle through which the gas passes causes it to squeeze itself at a high speed. This gas which is at high speed cuts the molten metal. This gas is also focused around the boundary of the cutting area in order to shield the cut. In recent days, plasma cutters are provided with a pilot arc in between the nozzle and the electrode in order to ionize the gas and generate plasma before arc transfer.

Here is a list of the top three plasma cutters in the market:

Lotos LTP5000D 50Amp Non-Touch Pilot Arc:

This plasma cutter is said to be the best one at an affordable price. Moreover, it has a pilot arc torch with dual modes of voltage such as 220V and 110V. The best part of the pilot arc torch is that it can cut through any dirty or rusty metal with ease. Since there is no direct contact between the material and the torch, there is no issue of the torch getting damaged. This plasma cutter also has a meter to show air pressure. It also has an effective cooling system.

Ramsond CUT 50DY:

This plasma cutter is well known for its lightweight nature weighing around 19 lbs only. Since this plasma cutter is lightweight, it is easy transportable. This plasma cutter also has a pilot arc torch. The maximum cut thickness of this plasma cutter is 3/4th inch and the maximum severe thickness is around 1 inch. This plasma cutter also has a digital amp gauge.

Lotos LT5000D 50A Air Inverter Plasma Cutter:

This plasma cutter is one of the best, even for industrial settings. It easily and smoothly cuts thick materials and has low maintenance. Only 50amp of current capacity is sufficient for smooth cutting. The torch of this plasma cutter is compact and thus it becomes easy for narrow cuttings. The fine cut of the material is ensured by the high rate of recurrence of DC plasma. The movement of the plasma is easy as the length of the cable is around 10 feet long. Another best point of this plasma cutter is that it releases less harmful gases. Like the Lotos LTP5000D, this also has a good cooling system.
