High Duty Cycle 220V/380V IGBT Inverter ARC 65A Plasma Cutter

●Assemble the cutting torch correctly

Install the torch correctly and carefully, making sure all parts fit together well and that gas and cooling air flow. Installation Put all the parts on a clean flannelette to avoid dirt sticking to the parts. Add proper lubricating oil to the O-ring, subject to the brightening of the O-ring, do not add more.

● Consumable parts should be replaced in time before they are completely damaged

Do not replace 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. So when you first notice that the cutting quality has declined, you should check the consumables in time.

● Clean the connecting thread of the cutting torch

When replacing consumable parts or daily maintenance and inspection, be sure to ensure that the inner and outer threads of the torch are clean, and if necessary, clean or repair the connecting thread.

● Clean the contact surface of the electrode and the nozzle

In many cutting torches, the contact surface between the nozzle and the electrode is a charged contact surface. If there is dirt on these contact surfaces, the torch cannot work normally and should be cleaned with a hydrogen peroxide cleaning agent.

● Check gas and cooling air every day

Check the flow and pressure of gas and cooling air every day. If insufficient flow or leakage is found, stop the machine immediately to troubleshoot.

● Avoid torch collision damage

Check the flow and pressure of gas and cooling air every day. If insufficient flow or leakage is found, stop the machine immediately to troubleshoot.

● Avoid torch collision damage

In order to avoid collision damage to the cutting torch, it should be programmed correctly to avoid the system from overrunning. Installing an anti-collision device can effectively avoid damage to the cutting torch during collision.

● The most common causes of torch damage

(1) Torch collision.

(2) Destructive plasma arc due to damage to consumable parts.

(3) Destructive plasma arc caused by dirt.

(4) Destructive plasma arc caused by loose parts.

(1) Do not grease the torch.

(2) Do not overuse O-ring lubricant.

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

(4) Do not use a manual cutting torch as a hammer.
