ENGINE BREAK-IN

Lincoln Electric selects high quality, heavy-duty indus- trial engines for the portable welding machines we offer. While it is normal to see a small amount of crankcase oil consumption during initial operation, excessive oil use, wetstacking (oil or tar like substance at the exhaust port), or excessive smoke is not normal.

Larger machines with a capacity of 350 amperes and higher, which are operated at low or no-load conditions for extended periods of time are especially susceptible to the conditions described above. To accomplish suc- cessful engine break-in, most diesel-powered equip- ment needs only to be run at a reasonably heavy load within the rating of the welder for some period of time during the engine’s early life. However, if the welder is subjected to extensive light loading, occasional moder- ate to heavy loading of the engine may sometimes be necessary. Caution must be observed in correctly loading a diesel/generator unit.

BATTERY CONNECTION

WARNING: Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.

Remove and discard the insulating caps from the neg- ative battery terminals. Attach and tighten negative battery cable terminals.

NOTE: This machine is furnished with wet charged batteries; if unused for several months, the batteries may require a booster charge. Be careful to charge the batteries with the correct polarity. Make sure that the batteries are level while charging.

WARNING

GASES FROM BATTERY can explode.

●Keep sparks, flame and cigarettes away from battery.

1.Connect the welder output studs to a suit- able resistive load bank. Note that any attempt to short the output studs by con- necting the welding leads together, direct shorting of the output studs, or connecting the output leads to a length of steel will result in catastrophic damage to the gener- ator and voids the warranty.

2.Set the welder controls for an output cur- rent and voltage within the welder rating and duty cycle. Note that any attempt to exceed the welder rating or duty cycle for any period of time will result in catastrophic damage to the generator and voids the warranty.

3.Periodically shut off the engine and check the crankcase oil level.

●INSTALLING A NEW BATTERY — disconnect negative cable from old battery first and connect to new battery last.

●CONNECTING A BATTERY CHARGER — remove battery from welder by disconnecting negative cable first, then positive cable and battery clamp. When reinstalling, connect negative cable last. Keep well ventilated.

●USING A BOOSTER — connect positive lead to battery first then connect negative lead to neg- ative battery lead at the lower control panel support.

BATTERY ACID can burn eyes and skin.

● Wear gloves and eye protection and be careful when working near battery.

●Follow instructions printed on battery.

ENGINE COOLING SYSTEM

The cooling system has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solu- tion as needed. (See Engine Manual or antifreeze container for alternate antifreeze recommendation.)

IMPORTANT: To prevent ELECTRICAL DAMAGE WHEN:

a)Installing new batteries.

b)Using a booster.

Use correct polarity — Negative Ground.

To prevent BATTERY BUCKLING, tighten nuts on bat- teries only until snug. DO NOT OVERTIGHTEN.
