Lincoln Electric 8 manual Angle of Operation, High Altitude Operation, Location / Ventilation

A-5 INSTALLATION A-5

Angle of Operation

Internal combustion engines are designed to run in a level condition which is where the optimum perfor- mance is achieved. The maximum angle of operation for the engine is 15 degrees from horizontal in any direction. If the engine is to be operated at an angle, provisions must be made for checking and maintain- ing the oil at the normal (FULL) oil capacity in the crankcase in a level condition.

When operating at an angle, the effective fuel capaci- ty will be slightly less than the specified 10 gallons.

High Altitude Operation

If the Ranger 8 will be consistently operated at alti- tudes above 5000 ft, a carburetor jet designed for high altitudes should be installed. This will result in better fuel economy, cleaner exhaust, and longer spark plug life. It will not give increased power which is decreased at higher altitudes. Engine horsepower is reduced by 3.5% per 1000 feet for altitudes above 377 feet.

CAUTION

Location / Ventilation

The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welder so that engine exhaust fumes are properly vented to an outside area.

WARNING

•Damage to the fuel tank may cause

fire or explosion. Do not drill holes in the Ranger 8 base or weld to the Ranger 8 base.

Wire Feeders

WARNING

Shut off welder before making any electrical connections.

Do not operate a Ranger 8 with a high altitude jet installed at altitudes below 5000 ft. This will result in the engine running too lean and result in higher engine operating temperatures which can shorten engine life.

Contact your local Onan, Kohler or Honda Authorized Dealer for high altitude jet kits that are available from the engine manufacturer.

WARNING

Muffler Relocation Shut off welder and allow muffler to cool before touching muffler.

The Ranger 8 is shipped with the exhaust coming out on the left side. The exhaust can be changed to the opposite side by removing the two screws that hold the exhaust port cover in place and installing the cover on the opposite side. (Operating the Ranger 8 without the cover in place will result in a higher noise level and no increase in machine output.)

Wire Feed (Constant voltage)

Connection of the LN-25 to the Ranger 8

•Shut the welder off.

•Connect the electrode cable from the LN-25 to the “ELECTRODE” terminal of the welder. Connect the work cable to the “TO WORK” terminal of the welder.

•Position the welder “Polarity” switch to the desired polarity, either DC (-) or DC (+).

•Position the “RANGE” switch to the “WIRE FEED” position.

•Attach the single lead from the LN-25 control box to the work using the spring clip on the end of the lead - it carries no welding current.

•Place the idler switch in the “AUTO” position.

•Adjust wire feed speed at the LN-25 and adjust the welding voltage with the output “CONTROL” at the welder.

NOTE: The welding electrode is energized at all times, unless an LN-25 with built-in contactor is used. If the output “CONTROL” is set below “3”, the LN-25 contactor may not pull in.
