1.13. EMC device classi cation
Radiation Class A Device.
Only can be used in the industrial area. If it is used in other area, it may cause connection and
radiation problems of circuit.
Radiation Class B device.
It can meet the radiation requirements of residential area and industrial area. It also can be used in
residential area which power is supplied by public low voltage circuit.
SKYARC 2850 MX
belong to Class A.
1.14. EMC measure
In the special situation, The speci ed area may be a ected, the standard of radiation limit value has
been complied with (eg: The device, which is easy e ected by electromagnetism, is used at the
installation location, or there is radio or TV near the installation location). In this condition, the
operator should adopt some appropriate measures to remove interference.
Accoring to the domestic and international standards, the ambient devices' electromagnetism
situation and anti-interference ability must be checked ：
- Safety device
- Power line, Signal transmission line and Date transmission line
- Date processing equipment and telecommunication equipment
- Inspection and calibration device
The e ective measures avoid the problem of EMC ：
a) Power source
Even though the power source connection meet rules, we still need to take additional measure to
remove the electromagnetic interference. (eg: Use the right power lter. )
b) The welding line
- Try to shorten the length of cable
- Put the cable together
- Be Far away from other cable
c) Equipotential connection
d) Ground connection of work-piece
- When necessary, use appropriate capacitance to connect the ground.
e) Shielding, when necessary
- Shield the ambient devices
- Shield the whole welding machine
