FEIFANKE 230V 50A Plasma Cutter Non Contact Low Frequency IGBT 2T/4T Cutting Torch with Blow Back for Cutting Stainless Steel Aluminium and Copper Maximum Cutting Thickness 25mm Low frequency ignition system without contact, which enables cutting of steel surfaces with dirt, rust or coatings. The torch head does not need to touch the metal, reducing energy consumption and electrode wear, which extends service life. Ideal for all conductive metals such as steel, copper, stainless steel, brass, aluminium and titanium. This plasma cutter automatically recognises the input voltage and provides a 60% duty cycle. The 50A torch allows a maximum cutting thickness of up to 1‘’ (25mm), with 15/32‘’ (12mm) being optimal for clean cuts, Made from high quality components, it offers 30% more durabili.
