General CNC plasma cutting machine is divided into the main cutting methods: contact arc cutting and non-contact arc cutting, but in the cutting time, the two cutting methods are different for different plates. Their main cutting nozzle Therefore, when we are purchasing a CNC plasma cutting machine or a manual plasma cutting machine, we must first have a clear understanding of the characteristics of the board we want to cut. Then choose the cutting method that suits us. In general, the advertising CNC cutting machine industry plasma cutting machines are contact cutting, using water-cooled cutting methods, while the carbon steel plate thicker plate cutting, CNC plasma cutting machine power is the use of non-contact plasma cutting machine, can effectively prevent the cutting nozzle In the process of perforation, the cutting nozzle and the electrode are lost! So how should we maintain the cutting torch tip in order to increase its lifespan when used in everyday equipment? A blank flange is one that is to be machined to a finished product.

Three tips for maintenance:
(a) minimize perforation cutting, perforation is the molten steel back splash will hurt the nozzle, this is one of the most important reasons for cutting nozzle damage, if you must perforation cutting, it is best to use a drill in the perforation to drill holes in the Cut from the pre-drilled hole;
(2) Cut as much as possible within the normal cutting thickness range of the cutting machine, try not to cut at the extreme cutting thickness, the normal cutting thickness of the domestic cutting machine is generally 60% of the maximum cutting thickness marked by the manufacturer (Example Domestic 100A Plasma Cutting Machine manufacturers marked the maximum cutting thickness is generally 32mm, but the normal normal cutting thickness is only 15-20mm), as far as possible in this thickness range, you can best protect the cutting nozzle;
(3) The distance from the cutting tip to the steel plate should be kept as constant as possible, generally around 3-8mm. If the distance is too far, not only the power consumption is too high, but also the penetrating power will decrease, and the electrode will be relatively consumed, which will reduce the service life of the electrode. Too close it is simpler, it is very expensive nozzle, the service life of the nozzle will decrease exponentially, even burned with the up; of course, the life of the plasma electrode nozzle is also related to other factors, such as: input voltage High and low, the quality of the electrode itself, the quality of the plasma cutting machine and the integrity of the equipment, the quality of the plasma torch, the user's experience, etc., but the most important is the above 3 points, these 3 points attention The electrode nozzle life will be greatly improved. ?
