Plasma cutting quickly became the world's preferred cutting technology. A veteran flame cutting user can obtain good cutting results for certain cutting applications, for example, cutting very thick mild steel. However, plasma has become the ideal choice for many metal cutting applications due to its superior cutting speed, excellent cutting quality, and ability to cut other types of metals.
![The reasons for the choice of metal cutting cutting plasma cutting machine]()
1. Better Cutting Quality Dross, heat affected zone, top fillet, and cut angle are some of the major factors that affect cut quality. Especially in the two aspects of scum and heat affected zone, plasma cutting is much better than flame cutting, plasma cutting edges do not substantially leave scum, and the heat affected zone is much smaller.
2. The scum plasma process uses a high temperature charged gas to melt the metal and blow the molten metal material off the cutting surface. Flame cutting is the use of chemical reactions between oxygen and steel to produce a cut, which can produce iron red slag or scum. Because of this process difference, plasma cutting produces less scum, and the attached scum is easier to remove. These scums can often be knocked down easily without grinding or erasing, greatly reducing the time required for secondary processing. Less sanding operation leads to higher productivity.
3. One issue that needs attention in heat-affected zone cutting is the size of the heat affected zone. High temperatures can change the chemical structure of the metal, causing the heated edges to darken (warm) and warp. If the heated edges are not removed, the workpiece may not be suitable for secondary welding. Regardless of the process used, the faster the torch moves, the smaller the heat affected zone. The rapid cutting characteristics of the plasma results in a smaller heat affected zone, which shortens the time spent on secondary processing to remove heated edges. Some flame cutting users may also be concerned about the tempering color. The heat-affected zone is not visible from the outside and the tempering color is not. It will discolor the metal. Also, the rapid cutting of the plasma makes the tempered area smaller.
4. Higher production efficiency The fastest cutting and perforating of plasma can reach 8.5 times that of flame cutting, and a significant increase in production efficiency can bring huge benefits, which is not counting the savings in preheating and secondary processing. time.
5. Lower costs per part When analyzing costs, it is important to understand the difference between operating costs and the cost of running each part or operating costs per meter. So how do you determine the actual cost of cutting a part? The operating cost per meter is the value obtained by dividing the total cost per hour required for cutting by the total length (meters) that can be cut in one hour. The costs involved in cutting include consumables, electricity, gas, labor, and ongoing expenses. The cost per part is the value obtained by multiplying the total cut length required to produce a part by the running cost per meter. Plasma systems cut faster and produce more parts in a given amount of time, so their cost per part is much lower. For handheld cutting, calculating the cost of each job or task can better assess the cost savings. The hourly operating cost multiplied by the total time required to complete the job is equal to the cost of the job. For flame cutting, be sure to calculate the warm-up time and lengthy secondary processing time within the required time.
6. Higher profitability The lower cost per part of the plasma system directly leads to an increase in profits. Cutting each part saves money and thus improves profitability. The more parts you cut per hour, the more total profit you increase.
7. Easier to use For users who use flame cutting, it takes time to learn and practice to master the flame chemistry parameters and maintain the flame chemistry. Hypertherm's Powermax series is operated by compressed air, and there is no gas to be mixed or regulated. If you are using a machine plasma system with a CNC or an automatic gas console, all parameters are set at the factory for the operator. No need to manually adjust the gas. In addition, the Powermax handheld plasma system can pull and cut, which means that the operator can drag the torch along the metal surface. No need to maintain any distance (a key element of good flame cutting). And it is easier to cut according to templates and patterns, especially curved templates and patterns. No need to adjust the gas, drag and drop cutting capabilities, and easy-to-use controls make the plasma system easier to learn.
8. More flexibility The plasma system can cut any conductive metal, including stainless steel, aluminum, copper and brass. In contrast, flame cutting machines use a chemical reaction between oxygen and iron in mild steel to cut it, and can only be used to cut low (carbon) steel. In addition, the plasma system can also be used to plan, mark or cut rusty, painted or even stacked metals. Moreover, you can also use the plasma system for bevel cutting or cutting steel mesh, which is difficult to achieve with flame cutting.
9. Higher safety The fuel used for flame cutting is a mixture of oxygen and gas. The most common fuel gases are acetylene, propane, MAPP, propylene, and natural gas. Acetylene is the most common of these because acetylene produces flames with higher temperatures and faster perforation rates than other gases. However, acetylene is an unstable and highly flammable gas that is extremely sensitive to excessive pressure, temperature, and even static electricity. Acetylene explosions can cause tens of thousands of dollars in property damage and cause serious injury to nearby people. Some plasma systems (such as the Powermax series) are usually operated by compressed air and do not require the use of flammable gases. Hypertherm's HPR and HSD plasma systems can use a variety of gases including air, most commonly oxygen and nitrogen. These gases are more stable than acetylene and do not require much special treatment. All types of thermal cutting produce some odors and noises, however, hot cuts using cutting beds and machine plasma systems can use water cutting beds, which can greatly reduce odors and noise. Most flame cutting should not be carried out underwater, as it may explode.
