High Duty Cycle 220V/380V IGBT Inverter ARC 65A Plasma Cutter from Leading China Suppliers and Factory
Detailed Information
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. 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.
Replace consumables in time
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. Check consumables when you first notice quality decline.
Clean the connecting thread
When replacing consumable parts or during daily maintenance and inspection, be sure to ensure that the inner and outer threads of the torch are clean. If necessary, clean or repair the connecting thread.
Clean contact surfaces
In many cutting torches, the contact surface between the nozzle and the electrode is a charged contact surface. If there is dirt, the torch cannot work normally and should be cleaned with a hydrogen peroxide cleaning agent.
Check gas and cooling air daily
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 during collision.
The Most Common Causes of Torch Damage
- Torch collision.
- Destructive plasma arc due to damage to consumable parts.
- Destructive plasma arc caused by dirt.
- Destructive plasma arc caused by loose parts.
Precautions
- Do not grease the torch.
- Do not overuse O-ring lubricant.
- Do not spray anti-splash chemicals while the protective sleeve is still on the torch.
- Do not use a manual cutting torch as a hammer.

Frequently Asked Questions
Q
How should I maintain the cutting torch O-ring?
Apply a proper amount of lubricating oil to the O-ring until it brightens. Be careful not to overuse the lubricant, and place all parts on clean flannelette during installation to avoid dust contamination.
Q
Why is it important to replace consumables before they are completely worn out?
Severely worn electrodes, nozzles, and swirl rings produce uncontrollable plasma arcs, which can easily cause permanent and severe damage to the cutting torch itself.
Q
What are the main parameters of the LGK-80E plasma cutter?
The LGK-80E features a rated input voltage of AC220V/380V, 12Kva input power, a current range of 20-80A, and is capable of cutting thicknesses up to 25mm using HF non-contact arc striking.
Q
What are the environmental requirements for installing this machine?
The system should operate in ambient temperatures between -10℃ and +40℃. Ensure the air inlets and outlets are unobstructed, keep the machine out of direct sunlight, and take measures to prevent dust buildup.
Q
What are the most common reasons for torch damage?
Torch damage is most commonly caused by torch collisions, loose parts, dirt on contact surfaces, and destructive plasma arcs resulting from damaged consumable parts.
Q
Can I use anti-splash chemicals on the torch?
Do not spray anti-splash chemicals while the protective sleeve is still attached to the torch. Always follow the precautions, which also advise against greasing the torch or using it as a hammer.
