Electromagnetic energy arising during welding and cutting operations can interfere with sensitive
electronic equipment such as microprocessors, computers, and computer-driven equipment such as
robots
Be sure all equipment in the welding area is electromagnetically compatible
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such
as on the floor
To avoid possible EMC damages, locate welding operation as far as possible (100 meters) from any
sensitive electronic equipment
Be sure this welding machine is installed and grounded according to this manual
If interference still occurs, the user must take extra measures such as moving the welding machine, using
shielded cables, using line filters, or shielding the work area
