DBe sure all equipment in the welding area is electromagnetically compatible.
DTo reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor.
DLocate welding operation 100 meters from any sensitive elec- tronic equipment.
DBe sure this welding machine is installed and grounded according to this manual.

1-6. 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 reproductive harm. Wash hands after handling.
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.

Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electro- magnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power- frequency electric and magnetic fields is a
To reduce magnetic fields in the workplace, use the following procedures:
1.Keep cables close together by twisting or taping them, or using a cable cover.
2.Arrange cables to one side and away from the operator.
3.Do not coil or drape cables around your body.
4.Keep welding power source and cables as far away from operator as practical.
5.Connect work clamp to workpiece as close to the weld as possible.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the device manufacturer before performing or going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If cleared by your doctor, then following the above procedures is recom- mended.
