Lincoln Electric IM604-B manual Angle of Operation Location / Ventilation, High Altitude Operation

9	9
Angle of Operation	Location / Ventilation

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 25 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.

High Altitude Operation

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.

WARNING

• Operate welder in open well ventilated area or vent the engine exhaust fumes outdoors.

The Ranger 8 LPG requires no adjustment for high altitude operation.

Muffler Relocation

WARNING

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.)

WARNING

Shut off welder before making any electrical

connections.

Wire Feed (Constant voltage)

Connection of the LN-25 to the Ranger 8

a.Shut the welder off.

b.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.

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

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

e.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.

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

g.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.
