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 visible and invisible (ultraviolet and infrared) rays D Always ventilate confined spaces or use 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.
