Since 2000 Lotos operated by Zion Global LLC introduced Inverter Technology in welding and cutting machines. Lotos" latest high frequency inverter technology utilizes IGBT to deliver a far more constant, concentrated and precise current to the cutting surface. This technology has been substantially reduced in size and weight of Inverter Plasma Cutters and tig welders. It helps you to easily achieve smooth, clean cuts of wide range of surfaces and material (e.g. stainless steel, alloy steel, brass, aluminum and other conductive material) with minimal heat input and without distortion of metal. Lotos Plasma cutters are designed especially for businesses and DIY (do-it-yourself) users, while fully accommodating the demands of professional operators.
