Connection of the LN-25 to the Ranger

INSTALLATION

A-5

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.

STACKING

RANGER 10,000 machines cannot be stacked.

CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

WARNING

Shut off welder before making any electrical connections.

------------------------------------------------------------------------

WIRE FEED (CONSTANT VOLTAGE) CONNECTION OF LN-15 ACROSS-THE-ARC WIRE FEEDER

The LN-15 has an internal contactor and the electrode is not energized until the gun trigger is closed. When the gun trigger is closed the wire will begin to feed and the welding process is started.

a.Shut the welder off.

b.Connect the electrode cable from the LN-15 to the“ELECTRODE” terminal of the welder. Connect the work cable to the “TO WORK” terminal of the welder.

c.Set the Polarity switch to the desired polarity, either DC (-) or DC (+).

d.Attach the single lead from the front of the LN-15 to work using the spring clip at the end of the lead. This is a control lead to supply current to the wire feeder motor; it does not carry welding current.

e.Set the “RANGE” switch to the “WIRE FEED-CV” position

f.Place the Engine switch in the “High Idle” position.

g.Adjust the wire feed speed at the LN-15 and adjust the welding voltage with the output “CONTROL” at the welder. Output “CONTROL” must be set above 3.

Note: LN-15 Control Cable model will not work with the RANGER 10,000.

10,000

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 engine 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.

CONNECTION OF K930-2 TIG MODULE TO THE RANGER 10,000.

The TIG Module is an accessory that provides high frequency and shielding gas control for AC and DC GTAW (TIG) welding. See IM528 supplied with the TIG Module for installation instructions.

Note: The TIG Module does not require the use of a high frequency bypass capacitor. However, if the RANGER 10,000 is used with any other high frequen- cy equipment, the bypass capacitor must be installed, order kit T12246.

INSTRUCTIONS

ADDITIONAL SAFETY PRECAUTIONS

Always operate the welder with the roof and case sides in place as this provides maximum protection from moving parts and assures proper cooling air flow.

Read and understand all Safety Precautions before operating this machine. Always follow these and any other safety procedures included in this manual and in the Engine Owner’s Manual.

WELDER OPERATION

WELDER OUTPUT

•Maximum Open Circuit Voltage at 3700 RPM is 80 Volts RMS.

•Duty Cycle is the percentage of time the load is being applied in a 10 minute period. For example, a 60% duty cycle represents 6 minutes of load and 4 minutes of no load in a 10 minute period. Duty Cycle for the RANGER 10,000 is 100%.

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” termi- nal of the welder.

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