ARC RAYS can burn eyes and skin. BUILDUP OF GAS can injure or kill. D Shut off shielding gas supply when not in use. Arc rays from the welding process produce intense D Always ventilate confined spaces or use visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin.
1-3. Additional Symbols For Installation, Operation, And Maintenance FIRE OR EXPLOSION hazard. MOVING PARTS can cause injury. D Do not install or place unit on, over, or near D Keep away from moving parts such as fans. combustible surfaces. D Keep all doors, panels, covers, and guards D Do not install unit near flammables.
1-5. EMF Information Considerations About Welding And The Effects Of Low Frequency 1. Keep cables close together by twisting or taping them. Electric And Magnetic Fields 2. Arrange cables to one side and away from the operator. Welding current, as it flows through welding cables, will cause electro- magnetic fields.
