D

Have only qualified persons familiar with

electronic equipment perform this installation.

D

The user is responsible for having a qualified electrician prompt-

ly correct any interference problem resulting from the installa-

tion.

D

If notified by the FCC about interference, stop using the

equipment at once.

D

Have the installation regularly checked and maintained.

D

Keep high-frequency source doors and panels tightly shut, keep

spark gaps at correct setting, and use grounding and shielding to

minimize the possibility of interference.

ARC WELDING can cause interference.

D

Electromagnetic energy can interfere with

sensitive electronic equipment such as

computers and computer-driven equipment

such as robots.

D

Be sure all equipment in the welding area is

electromagnetically compatible.

D

To reduce possible interference, keep weld cables as short as

possible, close together, and down low, such as on the floor.

D

Locate welding operation  100 meters from any sensitive elec-

tronic equipment.

D

Be sure this welding machine is installed and grounded

according to this manual.

D

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.
