Plasma Cutting speed setting
According to the instructions of the device, set good cutting speed range or through experiments to determine the selection. Because of the material, different materials, different melting point, size thermal conductivity coefficient and thickness of the surface tension melting, etc., corresponding to the change the cutting speed.
1. Cutting speed can improve the quality of the slit, that is, slightly narrow the incision, the cut surface is smooth, and can reduce distortion.
2. Cutting speed too fast, so below the cutting line energy value to cut the crack required will not quickly melt the jet, cut melt spray closed a large number of resistance after the formation, immediately with the slag incision, cut surface is mass.
3. When the cutting speed is too low, due to the plasma arc is anode cutting, in order to maintain the arc itself stable anode spots, or anode region is bound from. Near the slit arc the place of conduction current, will also eject multiple heat radial, thereby expanding the incision, in the molten material on both sides of the incision at the bottom edge of the agglomeration, forming the slag and difficult to clean, formed by melting the incision due to overheating the upper edge of the round.
when the speed is very low, the arc will even go out because the slit is too wide. Therefore, good cutting quality and cutting speed are inseparable.
