Precautions Of Electromagnetic Compatibility - ANDELI TIG Series Instruction Manual

Precautions of electromagnetic compatibility

1. Overview
Welding brings electromagnetic interference.
Minimize the interference emission of arc welding equipment with proper installation way
and correct application method.
The products described in the manual belong to Class A equipment (all occasions except
residential area powered by public electrical power system).
Warning: Class A equipment is not applicable to residential area powered by public
electrical power system. It is difficult to guarantee electromagnetic compatibility because of
conduction and radiated interference.
2. Advice of environment assessment
Before installing the arc welding equipment, the user shall evaluate the potential
electromagnetic disturbance of the surrounding. The considerations are as follows:
 Check surrounding of arc welding equipment for other power cables, control cables, signals
and telephone wire.
 Check for broadcasting and television launching and receiving equipment;
 Check for computer and other controllers;
 Check for high security level equipment, such as industrial protective equipment;
 Consider the health of surrounding staffs, such as staffs with hearing aid and cardiac
pacemaker;
 Check for calibrating or detection equipment;
 Pay attention to immunity to interference of other equipment. The user shall make sure that
the surround equipment can be compatible. The additional protective measures may be
required;
 Welding or other activity time.
The environmental range is decided based on the building structure and possible activities.
This range may exceed the boundary of building.
3. Method of reducing radiation emission
 Public power supply system
