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: TIG = GTAW Stick = SMAW 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 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 5/97 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. D Ne pas placer l’appareil sur, au-dessus ou à proximité de surfaces infllammables. D Rester à l’écart des organes mobiles comme le ventilateur. D Maintenir fermés et fixement en place les portes, panneaux, recouvrements et dispositifs de protection.

SECTION 2 – INSTALLATION 2-1. Specifications Rated Weld Output Model Weld Output Mode NEMA Class II (40): 200 Amperes, 28 Volts AC, 40% Duty Cycle 60 Hz NEMA Class II (50): 300 Amperes, 32 Volts DC, 50% Duty Cycle NEMA Class II (40): 200 Amperes, 28 Volts AC, 40% Duty Cycle 50 Hz NEMA Class II (50): 300 Amperes, 32 Volts DC, 50% Duty Cycle Max.
2-3. Duty Cycle And Overheating Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. If unit overheats, thermostat opens, output stops, and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before welding. Y Exceeding duty cycle can damage unit and void warranty. A. AC Mode AC Mode: 40% Duty Cycle At 200 Amperes 4 Minutes Welding 6 Minutes Resting B.
2-4. Selecting A Location 1 2 Lifting Eye Lifting Forks Use lifting eye or lifting forks to move unit. 1 If using lifting forks, extend forks beyond opposite side of unit. Movement OR 2 3 4 Location And Airflow Rating Label (Under Access Door) Use rating label to determine input power needs. 3 4 Line Disconnect Device Locate unit near correct input power supply.

2-8. 115 Volts AC Duplex Receptacle Y Turn Off power before connecting to receptacle. 1 115 V AC Receptacle Receptacle is protected from overload by circuit breaker CB1 (see Section 4-2). Power output is shared between this receptacle and the Remote 14 receptacle (see Section 2-7). 1 Ref. ST-152 973-A 2-9.
2-10. Placing Jumper Links And Connecting Input Power Check input voltage available at site. 1 Jumper Link Label Check label – only one is on unit. 2 200 VOLTS 230 VOLTS 460 VOLTS 3 L L L L L L 460 VOLTS Input And Grounding Conductors Select size and length using Section 2-9. S-083 566-C 230 VOLTS Jumper Links Move jumper links to match input voltage. 4 575 VOLTS Line Disconnect Device Select type and size of overcurrent protection using Section 2-9.
SECTION 3 – OPERATION 3-1. Controls 1 2 3 4 5 8 1 Arc Force (Dig) Control For SMAW, control increases short-circuit amperage which allows the operator to use a very short arc length without sticking the electrode. Set control at 0 for GTAW. When set at 0 (zero), short circuit amperage at low arc voltage is the same as normal welding amperage. 2 Amperage/Voltage Adjustment Control For AC or DC CC welding, such as GTAW Ref.
SECTION 4 – MAINTENANCE & TROUBLESHOOTING 4-1. Routine Maintenance Y Disconnect power before maintaining. 3 Months Repair Or Replace Cracked Weld Cables Replace Unreadable Labels Clean And Tighten Weld Terminals 14-Pin Cord Torch, Electrode Holder, Or Gun Cable Replace Cracked Parts 6 Months OR Blow Out Or Vacuum Inside, During Heavy Service, Clean Monthly 4-2.
4-3. Troubleshooting Trouble No weld output; unit completely inoperative. Remedy Place line disconnect switch in On position (see Section 2-10). Check and replace line fuse(s), if necessary (see Section 2-10). Check for proper input power connections (see Section 2-10). Check for proper jumper link position (see Section 2-10). No weld output; fan on. If using remote control, place Output (Contactor) switch in Remote 14 position, and make sure remote control is connected to Remote 14 receptacle.
