1, plasma cutting machine every month and a half to 2 months to open the shell for dust treatment (such as blowing with compressed air or with high-precision electronic components cleaning agent cleaning and then blow dry with compressed air), to ensure the smooth completion of the host work.
2, to ensure that the host into the line of 3 compartments electric balance, do not appear lack of compartments or pressure difference is too large.
3, to ensure good grounding of the steel plate, the resistance of the steel plate to the earth should be no more than 3 ohms.
4, to maintain good conductivity between the positive grounding clamp and the steel plate being cut.
5, to ensure adequate gas pressure and flow, the pressure in the normal cutting of not less than 9 kilograms (on-board power supply not less than 6 kilograms), pay attention to the distance from the gas to the plasma host shall prevail.
6, try to cut in accordance with the cutting table parameter settings, such as arc pressure value, cutting height, perforation height, etc..
7、Try not to suspend the arc and perforation for a long time, in order to improve the service life of wearing parts.
8、When the plasma cutting is not used temporarily, please ensure enough heat dissipation of the host before stopping the machine, subject to the reduction of fan noise in the host.
9, in the feeling of plasma cutting machine cutting energy is insufficient (such as penetration of the steel plate, arc offset or trailing), please immediately stop the machine to check, prohibit the continuation of cutting.
10, each time before cutting, empty range of high-speed low-speed operation, shutdown maintenance, shutdown, to ensure that the cutting gun to maintain the high point of the lift position.
