Install the cutting torch correctly and carefully, ensure that all parts are well matched, and ensure that the gas and cooling air flow. Install all the parts on a clean flannel to avoid dirt sticking to the parts. Add proper lubricating oil to the O-ring, subject to the brightening of the O-ring, and no more.
Do not replace the consumable parts after they are completely damaged, because severely worn electrodes, nozzles and swirl rings will produce uncontrollable plasma arcs, which can easily cause serious damage to the cutting torch. Therefore, when the cutting quality is found to be degraded for the first time, the consumable parts should be checked in time.
When replacing consumable parts or daily maintenance and inspection, be sure to ensure that the internal and external threads of the cutting torch are clean. If necessary, clean or repair the connecting threads.
In many cutting torches, the contact surface between the nozzle and the electrode is a charged contact surface. If these contact surfaces are dirty, the cutting torch will not work properly and should be cleaned with hydrogen peroxide cleaning agent.
Check the flow and pressure of the gas and cooling air flow every day. If you find that the flow is insufficient or leaks, you should stop the machine immediately to troubleshoot.
In order to avoid collision damage to the cutting torch, it should be programmed correctly to prevent the system from overrun. The installation of an anti-collision device can effectively avoid damage to the cutting torch during collision.
(1) The cutting torch collides.
(2) Destructive plasma arc caused by damage to consumables.
(3) Destructive plasma arc caused by dirt.
(4) Destructive plasma arc caused by loose parts.
(1) Do not apply grease on the cutting torch.
(2) Do not overuse O-ring lubricant.
(3) Do not spray anti-splash chemicals while the protective cover is still on the cutting torch.
(4) Do not use the manual cutting torch as a hammer.
