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.

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.
