This kind of torch belongs to the new range of compressed air plasma torches with striking of the pilot arc without high frequency. This kind of torches has the following advantages as: -          Less electromagnetic disturbance, with consequent absence of problems for any electronic, radio, television, telephone and computer systems in the vicinity of the cutting position. -          Greater simplicity in design and production of the generator for plasma cutting. -          Less electric stress on the torch and on the respective connecting cables. -          Greater simplicity in comparison with other torches. -          A striking new design -          A new mechanical safety device- in the operation of the trigger-together with the existing electrical safety device has made these torches some of the safest and most reliable on the market.   The first trafimet automatic torch with air striking without high frequency.   As per the other torches of the S range, the striking without hifh frequency involves, as well as a series of remarkable advantages, less electromagnetic disturbance with consequent absence of problems for electronic control systems in automatic equipment.
