1-4. California Proposition 65 Warnings
Welding or cutting equipment produces fumes or gases
which contain chemicals known to the State of California to
cause birth defects and, in some cases, cancer. (California
Health & Safety Code Section 25249.5 et seq.)
Battery posts, terminals and related accessories contain
lead and lead compounds, chemicals known to the State of
California to cause cancer and birth defects or other repro-
ductive harm. Wash hands after handling.
MOVING PARTS can cause injury.
Keep away from moving parts such as fans.
Keep all doors, panels, covers, and guards
closed and securely in place.
H.F. RADIATION can cause interference.
High-frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.
Have only qualified persons familiar with elec-
tronic equipment perform this installation.
The user is responsible for having a qualified electrician
promptly correct any interference problem resulting from the
installation.
If notified by the FCC about interference, stop using the equip-
ment at once.
Have the installation regularly checked and maintained.
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.
Electromagnetic energy can interfere with sen-
sitive electronic equipment such as 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.
Locate welding operation 100 meters from any sensitive elec-
tronic equipment.
Be sure this welding machine is installed and grounded accord-
ing 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.
For Gasoline Engines:
Engine exhaust contains chemicals known to the State of
California to cause cancer, birth defects, or other reproduc-
tive harm.
For Diesel Engines:
Diesel engine exhaust and some of its constituents are
known to the State of California to cause cancer, birth
defects, and other reproductive harm.
