• Direct Radiation: Radiation from the machine 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.
5.3 LIFTING INSTRUCTIONS
The power source can be lifted using any of the handles.
