Matters Needing Attention In CNC Steel Plate Cutting Machine Operations

CNC plasma cutters enable the quick cutting of any electrically-conductive material. We can help you identify the best CNC plasma cutter for your needs, based on your job requirements and material thickness. 

Matters needing attention in plasma cutting operations

The cnc steel plate cutting machine used on site should be equipped with rain, moisture, and sun protection, and be equipped with corresponding fire fighting equipment. Cutting operations cannot be carried out in the open air on rainy days. When working in a humid area, the operator should stand in a place covered with insulating materials and wear insulating shoes to ensure the safety of the operator.

When cutting pressurized containers, sealed containers, oil drums, pipes, and workpieces stained with flammable gases and solutions. Eliminate the pressure in the container and pipeline first, eliminate flammable gases and solutions, and then flush toxic, harmful, and flammable substances. The container with residual grease should be rinsed with steam and alkaline water first. And open the lid, confirm that the container is cleaned, and then fill up with water before cutting. When cutting in the container, measures to prevent electric shock, poisoning, and suffocation should be taken.

Air holes should be left for cutting sealed containers, and equipment ventilation should be installed at the inlet and outlet if necessary. The lighting voltage in the container should not exceed 12V, and the operator and the workpiece should be insulated. A dedicated person should be placed outside the container for supervision. It is strictly forbidden to cut in the container that has been sprayed with paint and plastic. It is strictly forbidden to cut pressure vessels and pipes under pressure. Containers containing flammable and explosive materials cannot be cut.

Hazards

Like most tools on a worksite, working with a plasma cutter does pose its share of possible hazards. Noise, air quality, and electrocution are three of the most dangerous risks when working with a plasma cutter. Each of these risks can result in long-lasting health consequences.

Sparks, flames, and heat hazards are some of the dangers that MCR Safety directly addresses with personal protective equipment (PPE). The process of cutting through metal produces sparks and heat. If your skin is exposed to this hazard, you can quickly burn yourself. Likewise, a small spark could come in contact with your clothing, causing severe burns and personal injury. 

Before we highlight safety and PPE, it is essential to note that plasma workers also face repetitive motion injuries. Advancing technology in plasma cutters has created cutters that can be used for more extended periods. That means a welder can do more work with fewer breaks, leading to repetitive motion injuries if working for prolonged periods.

Safety protection

The lower part of plasma cutting should be set with a water tank. During the cutting process, the cutting part should be cut under water to avoid the toxicity of smoke to human body.

Avoid direct visual plasma arc during plasma arc cutting. Wear professional protective glasses and face mask to avoid eye and skin burns caused by arc light.

A large amount of toxic gas will be produced in the process of plasma arc cutting, which requires ventilation and wear multi-layer filtering dust mask.

During the plasma arc cutting process, it is necessary to wear towel, gloves, foot sheath and other labor protection appliances to prevent the skin from being burned by sparks.

The high frequency and electromagnetic radiation generated by the high frequency oscillator in the plasma arc cutting process will cause damage to the body, and some long-term practitioners even have infertility symptoms. Although there is no definite conclusion in the medical field and the industry, it is still necessary to do a good job of protection.
