WARNING

ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For additional safety information, it is strongly recommend- ed that you purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ELECTRICALLY powered equipment.

1.a. Turn off input power using the dis- connect switch at the fuse box before working on the equipment.

1.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s recommendations.

1.c. Ground the equipment in accordance with the U.S. National Electrical Code and the manufac- turer’s recommendations.

ARC RAYS can burn.

2.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.

2.b. Use suitable clothing made from durable flame- resistant material to protect your skin and that of your helpers from the arc rays.

2.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

ELECTRIC AND MAGNETIC

FIELDS may be dangerous

3.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and weldingmachines

3.b. EMF fields may interfere with some pacemak- ers, and welders having a pacemaker should consult their physician before welding.

3.c. Exposure to EMF fields in welding may have other health effects which are now not known.

3.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:

3.d.1. Route the electrode and work cables together - Secure them with tape when possible.

3.d.2. Never coil the electrode lead around your body.

3.d.3. Do not place your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side.

3.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.

3.d.5. Do not work next to welding power source.
