FEIFANKE 55A Plasma Cutter Non Contact Pilot Arc High Frequency Airflow IGBT 2T/4T Cutting Torch Maximum Cutting Thickness 20mm for Cutting Stainless Steel Aluminium and Copper Non-Contact Arcing Function:The plasma cutter has a non-contact high-frequency arc starting mode. It can cut steel surfaces with dirt, rust or coatings. The torch head does not need to contact the metal plate, which reduces energy consumption, electrode burnout and prolongs service life. Suitable for all conductive metals such as standard steel, copper, stainless steel, brass, aluminium and titanium. Also suitable for painted metal sheets and flash rusting Cutting Thickness:The plasma cutter machine adopts new and improved MCU technology with fully digital integrated control. Automatically detects input voltage wi.
