How to maintain the gas supply system in a plasma cutter with CNC in good working condition
To ensure the reliable operation of the gas supply system in a plasma cutter with CNC and extend the lifespan of consumable parts, the following actions should be performed regularly:
-
Check connections and hoses for rust. Small rust particles that enter the system can damage the equipment.
-
Monitor gas supply pressure. Ensure that the compressor's performance and hose diameter provide the necessary gas flow rate for your plasma cutting machine.
-
Inspect the compressor pump and pistons. A lack of oil in the pump may indicate a leak through the piston rings into the system.
-
Clean the compressor’s intake air filter. The filter should be clean and located away from sources of contamination such as dust.
-
Avoid manual adjustments of the gas flow without consulting the user manual. Incorrect settings can lead to equipment malfunctions.
Pay attention to the color of the plasma arc:
-
Bright white to blue: Optimal operating condition.
-
Dark orange to purple: Indicates gas contamination.
-
Green: May indicate damage to the electrode and melting of the copper housing; replace consumables immediately.
Following these guidelines will help maintain the gas supply system in the plasma cutter with CNC in good working condition and ensure high-quality cuts.
