SECTION 1 − SAFETY PRECAUTIONS − READ BEFORE USING rom_2007−04 Protect yourself and others from injury — read and follow these precautions. 1-1. Symbol Usage DANGER! − Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text. Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
FUMES AND GASES can be hazardous. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Keep your head out of the fumes. Do not breathe the fumes. If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases. If ventilation is poor, wear an approved air-supplied respirator.
1-3. Engine Hazards BATTERY EXPLOSION can BLIND. Always wear a face shield, rubber gloves, and protective clothing when working on a battery. Stop engine before disconnecting or connecting battery cables or servicing battery. Do not allow tools to cause sparks when working on a battery. Do not use welder to charge batteries or jump start vehicles. Observe correct polarity (+ and −) on batteries. Disconnect negative (−) cable first and connect it last. FUEL can cause fire or explosion.
HOT METAL from air arc cutting and gouging can cause fire or explosion. Do not cut or gouge near flammables. Watch for fire; keep extinguisher nearby. HOT PARTS can cause burns and injury. READ INSTRUCTIONS. Read Owner’s Manual before using or servicing unit. Stop engine and release air pressure before servicing. Use only genuine replacement parts from the manufacturer. Do not touch hot compressor or air system parts. Let system cool down before touching or servicing. 1-5.
H.F. RADIATION can cause interference. High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment. Have only qualified persons familiar with electronic equipment perform this installation. The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation. If notified by the FCC about interference, stop using the equipment at once.
SECTION 2 − CONSIGNES DE SÉCURITÉ − LIRE AVANT UTILISATION rom_2007−04fre Se protéger, ainsi que toute autre personne travaillant sur les lieux, contre les étincelles et le métal chaud. 2-1. Signification des symboles DANGER! − Indique une situation dangereuse qui si on l’évite pas peut donner la mort ou des blessures graves. Les dangers possibles sont montrés par les symboles joints ou sont expliqués dans le texte.
Une tension DC importante subsiste à l’intérieur des onduleurs après avoir coupé l’alimentation. Couper l’alimentation du poste et décharger les condensateurs d’entrée comme indiqué dans la Section Maintenance avant de toucher des composants. DES PIÈCES CHAUDES peuvent provoquer des brûlures graves. Ne pas toucher à mains nues les parties chaudes. Prévoir une période de refroidissement avant de travailler à l’équipement.

6-2. Description Of Controls (See Section 6-1) 1 Engine Switch Use switch to control ignition circuit, and to stop engine. 2 Choke Control Move Choke control to the left (Run) as the engine warms. This unit has a low oil level shutdown to prevent starting an engine that is too low on oil. The low oil level shutdown may not stop a running engine. Check oil level if the engine does not start, or has stopped and cannot be restarted. Use control to change engine air/fuel mix.
SECTION 7 − OPERATING AUXILIARY EQUIPMENT The welding generator provides power while welding and with the Amperage control in any position. However, under these conditions equipment connected to the welding generator may be subject to larger than normal voltage fluctuations. It is recommended that only lamps be powered under these conditions. 7-1. Generator Power Panel Receptacles 2 1 3 226 005 !

SECTION 8 − MAINTENANCE 8-1. Routine Maintenance ! Recycle engine fluids. = Check = Change = Clean * To be done by Factory Authorized Service Agent Stop engine before maintaining. See Engine Manual and Maintenance Label for important start-up, service, and storage information. Service engine more often if used in severe conditions.
8-2. Servicing Air Cleaner ! Stop engine. NOTICE − Do not run engine without air cleaner or with dirty element. 1. Cover 2. Precleaner Remove air cleaner cover. Wash precleaner with soap and water solution. Allow precleaner to air dry completely. Spread 1 tablespoon SAE 30 oil evenly into precleaner. Squeeze out excess oil. 3. Element Replace element if dirty or oily.
SECTION 9 − TROUBLESHOOTING 9-1. Troubleshooting A. Welding Trouble No weld output; no generator power output at ac receptacles. Remedy Be sure all equipment is disconnected from receptacles when starting unit. Have Factory Authorized Service Agent check brushes, slip rings, rotor, stator, and integrated rectifier SR1. No weld output; generator power output okay at ac receptacles. Check Amperage control setting (see Section 6-1). Check weld connections.
Trouble Erratic output at generator power ac receptacles. Remedy Check fuel level. Check Amperage control setting. Set Amperage control at max for generator power. Check receptacle wiring and connections. Check governor linkage for smooth, non-binding operation. Service air cleaner according to engine manual. Have Factory Authorized Service Agent check engine speed, and adjust if necessary. C. Engine Trouble Engine will not start. Remedy Check fuel level (see Section 5-3).

SECTION 12 − STICK WELDING (SMAW) GUIDELINES 12-1. Stick Welding Procedure Weld current starts when electrode touches workpiece. Weld current can damage electronic parts in vehicles. Disconnect both battery cables before welding on a vehicle. Place work clamp as close to the weld as possible. 1 5 2 3 4 2 Work Clamp Electrode A small diameter electrode requires less current than a large one. Follow electrode manufacturer’s instructions when setting weld amperage (see Section 12-2).

Troubleshooting − Porosity Porosity − small cavities or holes resulting from gas pockets in weld metal. Possible Causes Corrective Actions Arc length too long. Reduce arc length. Damp electrode. Use dry electrode. Workpiece dirty.
12-16. Troubleshooting − Incomplete Fusion Incomplete Fusion − failure of weld metal to fuse completely with base metal or a preceeding weld bead. Possible Causes Corrective Actions Insufficient heat input. Increase amperage. Select larger electrode and increase amperage. Improper welding technique. Place stringer bead in proper location(s) at joint during welding. Adjust work angle or widen groove to access bottom during welding.
12-19. Troubleshooting − Burn-Through Burn-Through − weld metal melting completely through base metal resulting in holes where no metal remains. Possible Causes Excessive heat input. Corrective Actions Select lower amperage. Use smaller electrode. Increase and/or maintain steady travel speed. 12-20. Troubleshooting − Waviness Of Bead Waviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal. Possible Causes Unsteady hand. Corrective Actions Use two hands.
