From Hobart to You Thank you and congratulations on choosing Hobart. Now you can get the job done and get it done right. We know you don’t have time to do it any other way. This Owner’s Manual is designed to help you get the most out of your Hobart products. Please take time to read the Safety precautions. They will help you protect yourself against potential hazards on the worksite. We’ve made installation and operation quick and easy.
TABLE OF CONTENTS The following terms are used interchangeably throughout this manual: MIG = GMAW WARNING This product, when used for welding or cutting, 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.) SECTION 1 – SAFETY PRECAUTIONS - READ BEFORE USING . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1. Symbol Usage . . . . . . . . . . . . . . . . . . . .
SECTION 1 – SAFETY PRECAUTIONS - READ BEFORE USING som _nd_5/97 1-1. Symbol Usage Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols. Y Marks a special safety message. . Means “Note”; not safety related. This group of symbols means Warning! Watch Out! possible ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the hazards. 1-2.
ARC RAYS can burn eyes and skin. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. D Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). D Wear approved safety glasses with side shields under your helmet.
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 combustible surfaces. D Do not install unit near flammables. D Do not overload building wiring – be sure power supply system is properly sized, rated, and protected to handle this unit. D Keep away from moving parts such as fans. D Keep all doors, panels, covers, and guards closed and securely in place.
1-5. EMF Information Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields 1. Keep cables close together by twisting or taping them. Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields.
SECTION 1 – CONSIGNES DE SECURITE – LIRE AVANT UTILISATION som _nd_Fre 4/97 1-1. Signification des symboles Signifie Mise en garde ! Soyez vigilant ! Cette procédure présente des risques de danger ! Ceux-ci sont identifiés par des symboles adjacents aux directives. Y Identifie un message de sécurité particulier. . Signifie NOTA ; n’est pas relatif à la sécurité.
LES RAYONS DE L’ARC peuvent provoquer des brûlures dans les yeux et sur la peau. Le rayonnement de l’arc du procédé de soudage génère des rayons visibles et invisibles intenses (ultraviolets et infrarouges) susceptibles de provoquer des brûlures dans les yeux et sur la peau. Des étincelles sont projetées pendant le soudage. D Porter un casque de soudage muni d’un écran de filtre approprié pour protéger votre visage et vos yeux pendant le soudage ou pour regarder (voir ANSI Z49.1 et Z87.
1-3. Dangers supplémentaires en relation avec l’installation, le fonctionnement et la maintenance Risque D’INCENDIE OU D’EXPLOSION. DES ORGANES MOBILES peuvent provoquer des blessures.
