How to extend the life of plasma cutting machine

How to extend the life of plasma cutting machine is the most concerned things of our customer.Now let Morn show you how to extend the life of machine CNC plasma cutting. The main information as follows:

1. The reasonable cutting distance
Accordance with the instructions of the machine, you need use the reasonable cutting distance. The cutting distance that is cut from the nozzle and the workpiece surface. When the perforation, 2 times the distance as far as possible from the normal cut or by plasma arc can deliver the maximum height.
2. Please ensure the correct plasma pressure and flow
Plasma proper pressure and flow of life is very important consumption items. If the pressure is too high, it will greatly reduce the life of the electrode. If the pressure is too low, the nozzle life will be affected.
3. The cutting edge should start
Start cutting from the edge as possible, instead of perforated cutting. Using as a starting point edge will extend the life of consumable parts, the correct way is nozzle directly at the edge of the workpiece before starting the plasma arc.
4. Do not overuse the nozzle use
If nozzle is over using (over the nozzle operating current), it will quickly damage the nozzle. Current intensity should be 95% of the operating current is appropriate nozzle. For example the nozzle 100A current intensity should be set to 95A.
5. Use demineralized water injection and cutting torch
Hard water will cause precipitation of metal impurities on the nozzle ring, which will affect air flow and reduce the quality and shorten the torch consumable parts life.
6. Please check the air flow and cooling flow every day
One of the most common causes of damage torch is the lack of cooling flow, need regular checks to torch flow and pressure (the case of air-cooled) or coolant (case of water), if found insufficient airflow or leakage, should immediately stop excluded malfunction.
7.Ensure correct air pressure and plasma flow
Plasma proper pressure and flow of life is very important consumption items. If the pressure is too high, it will greatly reduce the life of the electrode; pressure is too low, the nozzle life will be affected.
