1909-01 Section 4 - Plasma cutting General information and choice criteria The new range of plasma cutting equipment developed by SAF-FRO heralds a technological revolution in the eld of compressed air plasma cutting for manual applications. Thanks to its user-comfort, speed and ease of use, these machines provide outstanding levels of industrial performance. SAF-FRO and plasma cutting: tradition and passion This range of portable, single and three phase plasma cutters have been designed to meet the needs of all industrial user applications.They are capable of high-quality cutting on all conductive metals in thicknesses of up to 50 mm. Every installation consists of a power source and a patented cutting torch, designed to offer excellent user comfort and optimum outputs. Drag cutting Plasma gouging The direct contact between the cutting nozzle and the workpiece provides several benets in comparison with the “distance cutting” method. This particular position allows most of the fume, spatter and arc radiation to be kept under the metal sheet thus protecting the operator. The result of a drag cut is very clean and the resulting kerf is a much narrower, superior precision quality cut. The drag cutting process is ideal up to 8 mm thickness in all applications where accuracy is important. The plasma gouging process is performed with a standard plasma cutting torch changing only the nozzle, skirt and skate. Using the same principle of plasma cutting it allows metal to be removed in an efcient, precise and clean way. 2007-114 The benets of the SAF-FRO gouging process are: • reduced noise and fume compared with other thermal gouging methods, • high metal removal rate (up to 12 kg / hour) with superior precision, • reduced risk of carbon contamination compared with the arc gouging process, • possibility to gouge ferrous and non-ferrous metals. Arc Plasma advantages Distance cutting Distance cutting makes full use of the generator power, thus increasing the depth of cut.It is also suitable for precision work due to the excellent view of the cutting arc. 58 • Cutting of all metallic material conducting electricity • Easy to use, it gives professionnal results from the rst cut • Faster than others cutting processes • More accurate results.
