What Sets Lotos Plasma Cutters Apart From Its Competitors?

Duty cycle

In layman’s language, Duty Cycle is the ratio of time of device operated and the ratio of on and off period. It is expressed in percentage. 

A heavy-duty plasma cutter has a high duty cycle. It means the cutter has a high production rate. This is because the downtime is less and production speed is more.

Power input

This is based on the power distribution frequency of your country. It is better to buy a plasma cutter that has a dual voltage operation system. It allows you to work on both frequencies. However, you will need a pigtail extension for this.

Mobility

Plasma Cutting technology is now portable in small units with a compact design and high efficiency. They are easy to operate under conventional cutters. Hence, choose a cutter that allows you to be mobile in operation.

Safety

Prefer getting a plasma cutter with air compressor compatibility or with an inbuilt air compressor. A separate air compressor tank can increase the risk of explosion around the work area.

Cut Thickness

The plasma cutter is categorized according to its cutting thickness. Depending upon the type of work, you should choose the cutter that operates at your job thickness.

Cut Rating

There are three types of cutting plasma rate. Firstly, the machine that can cut at a rate of 10 inches per minute. This is called a rate cut. Second is the quality cut at lower speed and higher thickness. The third is the severe cut. It is the maximum cut that can be achieved. 

The cut rating is important, and depending upon your job type, you can select the convenient plasma cutter.

Operating Cost

The consumption rate of a plasma cutter is different for different machines and consumables types. This adds to the operating costs. 

The consumption rate may or may not be mentioned. You will have to ask the salesperson to guide you towards the cutter with optimum operating costs

Summing it Up

Lotos LTP5000D 50Amp Non-Touch Pilot Arc Plasma Cutter tops my list due to its technology. It has all topped all the parameters necessary for a plasma cutter.

These reviewed Plasma Cutters are not only cost-effective but also environmentally friendly. The operation costs and maintenance costs of these cutters are lower. They are easy to use. On the contrary to their lightweight and size, these cutters enhance the aesthetics of cutting parts. You can cut intricate shapes of small size at a faster precision and pace.
