  • Page 4: Safety Warning

    SAFETY WARNING The safety notes listed in this manual is to ensure correct use of the machine and to keep you and other people from being hurt. The design and manufacture of plasma cutting machine considers safety. Please refer to the safety warning listed in the manual to avoid accidents.
  • Page 5 Please follow the rules below to avoid heavy accidents. Never use the equipment to do other things but cutting. Follow related regulations for the construction of the input-driven power source, choice of place, usage of high-pressure gas, storage, configuration, safe-keeping of workpiece after cutting and disposal of waste, etc.
  • Page 6 Keep hot workpiece after cutting away from flammable gas. Do move away the combustible around when cut the dooryard, ground and wall,. The wire connection of base metal should be as close to the cutting place as possible. Never cut those facilities with gas pipe or airtight slot. Put fire extinguisher around the cutting area to prevent fire.
  • Page 7 Fix the gas cylinder with appropriative holder and other relative parts. Never put the cylinder under high temperature or sunshine environment. Keep your face away from the gas cylinder exit when opening it. Put on the gas shield when it is not used. Never put the torch on the gas cylinder.

It may need extra preventive measures when the equipment is used in particular location. Before the installation, please estimate the potential electromagnetism problems of the environment as follows.

  • Page 9: Machine Description

    MACHINE DESCRIPTION The plasma welding machine adopts the most advanced inverter technology, it’s applicable for plasma cutting system with compressed air. The development of welding and cutting equipment benefits from the appearance of the inverter power supply theory and components. Inverter cutting machine, firstly transfers the working voltage of 50/60Hz to high frequency (above 100KHz) via high-power device MOSFET, then reduces the voltage and adjusts the current, delivers high-power cutting current via PWM technology.
