ARC WELDING can cause interference.
DElectromagnetic energy can interfere with sensitive electronic equipment such as computers and
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.
DIf 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.

1.6EMF Information
Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields − Background Paper,
To reduce magnetic fields in the workplace, use the following procedures:
1.Keep cables close together by twisting or taping them.
2.Arrange cables to one side and away from the operator.
3.Do not coil or drape cables around the 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 possi- ble.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor, then following the above procedures is recommended.
