Frequently Asked Questions
What is pilot arc technology and why is it important?
Pilot arc technology allows the plasma cutter to start the arc without direct contact with the metal, enabling cuts on painted, rusty, or rough surfaces without stopping or damaging the consumables.
Can plasma cutters run on generators for outdoor use?
Many portable plasma cutters, especially those with inverter technology, can run on clean, stable power from generators. Always check the manufacturer’s guidelines for generator compatibility and power requirements.
How thick can a portable plasma cutter cut?
Cutting capacity varies by model but typically ranges from 1/4 inch up to 3/4 inch for portable units. Choosing a cutter with a thickness rating slightly above your project needs ensures better performance and cleaner cuts.
Do I need an air compressor for plasma cutting outdoors?
Yes, plasma cutters use compressed air to blow away molten metal and shield the arc. Some models require an external air compressor, while others have built-in or integrated units for easier portability.
Are plasma cutters safe to use outdoors?
Plasma cutters can be safely used outdoors if proper safety measures are followed, including wearing protective gear, ensuring dry conditions to avoid electrical hazards, and working in well-ventilated areas.
