The immunity of other equipment in the environment: the user shall ensure that other
equipment being used in the environment is compatible: this may require additional
protection measures.

The size of the surrounding area to be considered will depend on the structure of the
building and other activities that are taking place. The surrounding area may extend
beyond the boundaries of the premises.
Interference may be transmitted by a high frequency initiated or stabilized arc welding power
source in the following ways:
• Direct radiation: Radiation from the equipment can occur if the case is metal and is not
properly grounded. 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 grounded.
• Transmission via the supply lead: Without adequate shielding and filtering, high
frequency energy may be fed to the wiring within the installation (mains) by direct
coupling. The energy is then transmitted by both radiation and conduction. Adequate
shielding and filtering is provided in the power source.
• Radiation from welding leads: Radiated interference from welding leads, although
pronounced near the leads, diminishes rapidly with distance. Keeping leads as short as
possible will minimize this type of interference. Looping and suspending of leads should
be avoided wherever possible.
• Re-radiation from unearthed metallic objects: A major factor contributing to interference
is re-radiation from unearthed metallic objects close to the welding leads. Effective
grounding of such objects will prevent re-radiation in most cases.
