在高频焊机旁长期工作对健康有危害吗
        There is a lot of concern these days about the long term health effects of exposure to low frequency, non
ionizing radiation of the type generated by power lines, computer monitors and even cellular phones. Induction
welders have the potential to produce the same type of radiation, particularly in the vicinity of the coil,
transmission lines and tank circuit components. So far there is no proven link between this type of radiation,
and any type of health hazard, but avoiding unnecessary exposure is probably a wise precaution. Electromagnetic
radiation drops off very rapidly with distance from the source, and at the 3 to 10 ft. distance at
which mill operators are exposed, the risk to health is minimal.

        At close range, induction welders can affect the operation of certain types of cardiac pacemakers. If you
have one of these, you should not work in the vicinity of a high frequency tube welder without first consulting
your doctor.

        Induction welders concentrate a lot of energy into a very small area, and the voltages and currents applied to
the work coil are very high. The high frequencies used by welders are not generally considered to constitute
an electrical shock hazard but serious deep burns will result if you touch any part of the coil, coil clamps or
bus bars while the welder is operating. These burns can be severe enough to completely incinerate a finger!
No part of the body should be brought closer than 6" from any metal object that is electrically connected to
the welder output terminals.

       If the welder uses an SCR phase angle controller, and the B+ voltage is not adequately filtered, the high
frequency output may be modulated at some multiple of the line frequency. This presents a very high shock
hazard.
