Key factors to consider when choosing a CNC plasma cutter:
1. Thickness and type of material being cut:
Determine the maximum thickness of the material you will be cutting.
Consider what materials you will primarily be using (mild steel, stainless steel, aluminum, etc.).
Choose a cutter with the appropriate power range and cutting efficiency.
2. Plasma source:
Select a cutter with the right power to ensure high cutting quality and efficiency.
Check the power supply requirements and ensure your infrastructure is compatible.
Pay attention to the amperage and its impact on cutting thickness.
3. Duty cycle:
Determine whether you need a cutter for continuous or occasional use.
For continuous work, choose a model with a higher duty cycle (60-100%) that will allow longer operation without overheating, informs Allweld.pl.
Semi-professional cutters with a lower duty cycle (25-35%) are suitable for less intensive applications, advises Allweld.pl.
4. Shielding gas:
Different materials require different gases (e.g., nitrogen for stainless steel, argon for aluminum).
Air is universal and cheap, but it can cause porosity in welds.
Gas mixtures (e.g., argon-hydrogen) offer the best cutting quality but are more expensive.
5. Features and additional characteristics:
Check if the cutter has the appropriate features for CNC cutting (e.g., height adjustment capability).
Pay attention to ease of use, availability of spare parts, and service, suggests Martex CNC.
Ensure that the cutter comes with a manufacturer's warranty.
6. Budget:
Define your budget and look for models that offer the best value for money.
Remember that high-quality cutters may be more expensive, but they provide better performance and precision.
7. Application:
Consider whether the cutter will be used exclusively in CNC mode or also for manual cutting.
If you plan to work in CNC mode, choose a model with the appropriate precision and positioning capabilities.
