Page Cold Weather Engine Operation This condition occurs when the temperature is near freezing and the rela- tive humidity is high. Page Solid Wire Applications Page 32 B. Page Optional Generator Power Receptacles Generator power decreases as weld current increases. Set Fine Control R1 at 10 for full genera- tor power. Page Simultaneous Weld And Power Precleaner Wash precleaner with soap and wa- ter solution.

Allow precleaner to air dry completely. Welding Troubleshooting Trouble Low or no weld output; generator pow- Check control settings. Check weld connections. Check fuse F1, and replace if open see Section or Page Engine Troubleshooting Trouble No generator power or weld output. Be sure all equipment is disconnected from receptacles when starting unit.

Check fuses F1 and F2, and replace if open see Section or Check plug PLG6 connection. Clean battery, terminals, and posts with baking soda and water solution; rinse with clear water. Periodically recharge battery approximately every 3 months. Replace battery. Check voltage regulator and connections according to engine manual. Page 53 A OM Page Your unit may differ from those shown.

Selecting Equipment Grounding When Supplying Building Systems Ground Device Use ground device as stated in electrical codes. Ground generator to system earth ground if supplying power to a premises home, Page 56 Page 57 Page 58 Page 59 Page 60 Weld current can damage elec- tronic parts in vehicles. Discon- nect both battery cables before welding on a vehicle.

Place work clamp as close to the weld as possible. Page 63 Poor Weld Bead Characteristics Conditions That Affect Weld Bead Shape Weld bead shape is affected by electrode angle, arc length, travel speed, and thickness of base metal. Electrode Movement During Welding Normally, a single stringer bead is satisfactory for most narrow groove weld joints; however, for wide groove weld joints or bridging across gaps, a weave bead or multiple stringer beads work better.

Page Butt Joints Butt Joints Page Weld Test Damp electrode. Workpiece dirty. Arc length too long or voltage too high. OM Page 62 2 To 3 in mm Page 67 Improper welding technique. Improper weld technique. Insufficient heat input. Page 68 Use two hands. Practice technique. Possible Causes Excessive heat input. Conditions That Affect Weld Bead Shape Weld bead shape depends on gun angle, direction of travel, electrode extension stickout , travel speed, thickness of base metal, wire feed speed weld current , and voltage.

Page Gun Movement During Welding Gun Movement During Welding Normally, a single stringer bead is satisfactory for most narrow groove weld joints; however, for wide groove weld joints or bridging across gaps, a weave bead or multiple stringer beads works better.

Voltage too high. Electrode extension stickout too long. Insufficient shielding gas at welding arc. Dirty welding wire. Wrong gas. Unsteady hand. Page Common Mig Shielding Gases Many different combinations mixtures of shielding gases have been developed over the years. 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. 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 ventilation is poor, wear an approved air-supplied respirator. 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. FUEL can cause fire or explosion. Do not cut or gouge near flammables. Watch for fire; keep extinguisher nearby. 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.

High-frequency H. 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. Suivre les recommandations dans OSHA Utiliser les supports de la remorque ou des blocs pour soutenir le poids. A complete Parts List is available at www.

Do not exceed D d tilt il angles l or engine i could ld be damaged or unit could tip. Volt-Ampere Curves A. Curves of all other settings fall between the curves shown. Generator Power Curve The generator power curve shows the generator power in amperes available at the receptacles. Duty Cycle Duty cycle is the percentage of 10 minutes that unit can weld at rated load without overheating. Installing Welding Generator Movement! Do not lift unit from end.

Do not weld on base. Welding on base can cause fuel tank fire or explosion. Bolt unit down using holes provided in base. Always securely fasten welding generator onto transport vehicle or trailer and comply with all DOT and other applicable codes. Do not mount unit by supporting the base only at the four mounting holes. Engine must be cold and on a level surface. Unit is shipped with 10W30 engine oil. Follow run-in procedure in engine manual. However, some conditions may cause engine damage before the engine shuts down.

Installing Exhaust Pipe! Engine backfire can cause severe burns or other injuries. Do not point exhaust pipe toward control panel. Keep away from exhaust outlet. Point exhaust pipe in desired direction but always away from front panel and direction of travel. Be sure to tighten exhaust clamp nuts. Exhaust clamp supplied with muffler. Connecting to Weld Output Terminals!

Stop engine. Connect electrode holder cable or electrode weld cable to Electrode terminal for Stick and MIG welding. Connect torch cable to Electrode terminal for TIG welding. Use Process Selector switch to select type of weld output see Section Weld Output Terminals Turn off power before connecting to weld output terminals. Do not use worn, damaged, undersized, or poorly spliced cables. Place switch in Run position to operate most MIG equipment. This condition occurs when the temperature is near freezing and the relative humidity is high.

Ice forms on the throttle plate and inner bore of the carburetor. The engine typically restarts without problems but soon stalls again. This section provides general guidelines and may not suit all applications. For best arc starts and best results using weld and generator power together, use a low Coarse Range setting and the Fine control set at 7 or higher. Solid Wire Applications! This section provides general guideTypical Control Settings For. The control panel shows the typical 1 2 3 settings for welding with.

Use Argonbased shielding gas. This Typical Control Settings For. The control panel shows the typi1 2 3 cal settings for welding with. Work 12 5 Plug and sensing lead not used in this application. Standard Receptacles!

Generator power decreases as 1 weld current increases. Set Fine Control R1 at 10 for full generator power. Optional Generator Power Receptacles! Generator power decreases as weld current increases. Routine Maintenance Robin-Powered Units! Recycle engine fluids. See Engine Manual and Maintenance Label for important start-up, service, and storage information.

Service engine more often if used in severe conditions. Allow precleaner to air dry completely. Squeeze out excess oil. Stop engine and let cool. Oil Fill Close valve and valve cap before adding oil and running engine. Fill crankcase with new oil to full mark on dipstick see Section If necessary, adjust speeds as follows: Start engine and run until warm.

Remove rear panel and air cleaner to access idle speed adjustments. If F1 opens, weld output stops or is low. Routine Maintenance Kohler-Powered Units! Full Close valve and valve cap before adding oil and running engine.

Turn Fine Control to If F2 opens, generator power output stops or is low. Welding Troubleshooting Trouble Low or no weld output; generator power output okay at ac receptacles. Remedy Check control settings. Check weld connections. Check fuse F1, and replace if open see Section or No weld output or generator power output at ac receptacles.
