9. High Frequency Considerations
9.1 Introduction
The importance of correct installation of high frequency welding equipment cannot be over-
emphasised. Interference due to high frequency initiated or stabilised arc is almost invariably traced
to improper installation. The following information is intended as a guide for personnel installing
high frequency welding machines.
9.2 Warning
a) Explosives
The high frequency section of this machine has an output similar to a radio transmitter. The
machine should NOT be used in the vicinity of blasting operations due to the danger of
premature firing.
b) Computers
It is also possible that operation close to computer installations may cause computer
malfunction.
9.3 High Frequency Interference
Interference may be transmitted by a high frequency initiated or stabilised arc welding machine in the
following ways:
a) Direct Radiation
Radiation from the machine can occur if the case is metal and is not properly earthed. It can
occur through apertures such as open access panels. The shielding of the high frequency unit in
the Power Source will prevent direct radiation if the equipment is properly earthed.
