Maintenance of Plasma Cutting Torch

　1. Properly assemble Plasma Cutting Torch

　　Install the torch correctly and carefully to ensure that all parts are well matched to ensure gas and cooling airflow. Installation Place all parts on a clean flannel to prevent dirt from sticking to the parts. Add the appropriate lubricating oil to the O-ring, which is subject to the brightening of the O-ring.

　　2. Replace consumables in time before they are completely damaged

　　Do not replace the consumables with complete damage, as severely worn electrodes, nozzles, and swirl rings will create an uncontrolled plasma arc that can easily cause severe damage to the torch. Therefore, when the quality of the cut is found to be degraded for the first time, the consumables should be inspected in time.

　　3. Cleaning the connecting thread of the torch

　　When replacing consumables or routine maintenance inspections, be sure to clean the internal and external threads of the torch and, if necessary, clean or repair the connecting threads.

　　4. Cleaning the contact surface of the electrode and the nozzle

　　In many torches, the contact surface of the nozzle and the electrode is a charged contact surface. If there is dirt on these contact surfaces, the torch will not work properly and should be cleaned with a hydrogen peroxide cleaning agent.

　　5. Check gas and cooling gas daily

　　Check the flow and pressure of the gas and cooling air flow daily. If the flow is found to be insufficient or leaking, stop the queuing failure immediately.

　　6. Avoid torch collision damage

　　In order to avoid damage to the torch collision, it should be properly programmed to avoid the system from overrunning. The installation of the anti-collision device can effectively avoid the damage of the torch during the collision.

　　7. The most common cause of torch damage

　　(1) Torch collision.

　　(2) A destructive plasma arc due to damage to the consumables.

　　(3) Destructive plasma arc caused by dirt.

　　(4) Destructive plasma arc caused by loose parts.

　　8. Precautions

　　(1) Do not apply grease to the torch.

　　(2) Do not overuse the O-ring lubricant.

　　(3) Do not spray splash-proof chemicals while the protective cover is still on the torch.

　　(4) Do not use the manual torch as a hoe
