RASOR™ 90/120 SilverLine® OXYGEN CUTTING PARAMETERS Rasor 120 Torch K35-006 65-0442-006 O-Ring Kit K35-021 65-0434-021 Cooling Tube, 90/120 Amp (red band) C35-110 65-0442-009
To achieve maximum SilverLine® Electrode life: ▪ A fully used electrode will have a pit depth of .100 in. (2.5 mm). Standard electrodes only achieve a pit depth of .050 in. (1.3 mm). ▪ As the electrode wears, the torch will get closer to the plate. To compensate for this, increase arc voltage in 2-volt increments up to 10 volts higher than the initial setting. ▪ Make sure the torch is purged for at least 30 seconds after each parts change to remove all moisture. ▪ Leak check the torch after purging to make sure all o-ring and metal-to-metal seals are working as designed.
SilverLine® Electrode 90/120 Amp C35-1020 65-0442-001
To achieve maximum nozzle life: ▪ Use 90 amp shield and spacer ring for all cutting. This shield provides greater nozzle protection. ▪ Use at least 3 kg/cm2 (bar) assist gas on 1/4" plate and above. Increased assist gas flow helps to keep the nozzle clean and cool. ▪ Clean the shield and nozzle periodically to remove slag buildup and prevent double arcing. ▪ Use the lowest possible pilot arc setting to achieve arc transfer. Pilot current is adjustable with a toggle switch on the power supply or as a function in the Operator Control Unit (OCU).

Rasor 90/120 SilverLine® Oxygen Electrode Life Half Used Electrode
Fully Used Electrode
This SilverLine® electrode is only half consumed. The pit in the center of the part is .040 in. (1.0 mm). Electrodes are often removed prematurely due to cut quality deterioration related to nozzle failure. Additional life can be achieved by replacing the nozzle.
This SilverLine® electrode has provided full use. The pit depth is .100 in. (2.5 mm). The operator increased the arc voltage by 8 volts from the first cuts made with this electrode to the last. This maintains a constant distance between the torch and the work-piece throughout the life of the electrode.
