Plasma Cutting Machine torch maintenance
1. Correctly assemble the cutting torch
Install the cutting torch correctly and carefully to ensure that all parts are in good coordination and ensure that the gas and cooling air flow. Installation Place all components on a clean flannel to prevent dirt from sticking to the components. Add appropriate lubricating oil to the O-ring, and the O-ring should become brighter.
2. Consumable parts should be replaced in time before they are completely damaged
Do not replace the consumable parts after they are completely damaged, because severely worn electrodes, nozzles and vortex rings will produce an uncontrollable plasma arc, which can easily cause serious damage to the torch. Therefore, when the quality of cutting is found to decrease for the first time, the consumables should be checked in time.
3. Clean the connection thread of the torch
When replacing consumable parts or during routine maintenance and inspection, make sure that the internal and external threads of the torch are clean. If necessary, the connection threads should be cleaned or repaired.
4. Clean the contact surface between electrode and 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 it 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 every day. If it is found that the flow is insufficient or there is a leak, it should be immediately stopped and queued for failure.
6. Avoid torch collision damage
In order to avoid torch collision damage, it should be correctly programmed to avoid system overrun. Installing anti-collision device can effectively avoid torch damage during collision.
7. The most common causes of torch damage
(1) The 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.
8. Precautions
(1) Do not apply grease to the torch.
(2) Do not overuse O-ring lubricant.
(3) Do not spray splash-proof chemicals while the protective sleeve is still on the torch.
(4) Do not use the manual torch as a hammer
