Lincoln Electric RANGER IM511-D - Manual (Page 19)

Stopping the Engine
Remove all welding and auxiliary power loads and
allow engine to run at low idle speed for a few minutes
to cool the engine.
Stop the engine by placing the “Engine” switch in the
“OFF” position.
A fuel shut off valve is not required on the Ranger 8
because the fuel tank is mounted below the engine.
Break-in Period
It is normal for any engine to use a greater amount of
oil until the break-in is accomplished. Check the oil
level twice a day during the break-in period (approxi-
mately 50 running hours)).
IMPORTANT: IN ORDER TO ACCOMPLISH THIS
BREAK-IN, THE UNIT SHOULD BE SUBJECTED TO
MODERATE LOADS, WITHIN THE RATING OF THE
MACHINE. AVOID LONG IDLE RUNNING PERIODS.
REMOVE LOADS AND ALLOW ENGINE TO COOL
BEFORE SHUTDOWN.
The engine manufacturer’s recommendation for the
running time until the first oil change is as follows:
The oil filter is to be changed at the second oil change.
Refer to the Engine Owner’s Manual for more informa-
tion.
Welding Processes
Stick (Constant Current) Welding
Connect welding cables to the “TO WORK” and
“ELECTRODE” studs. Start the engine. Set the
"POLARITY” switch to the desired polarity. Set the
output “CONTROL” or remote output control to max
(10) and the “RANGE” switch to the setting that is
closest to the recommended current for the electrode
being used and make a trial weld. A fine adjustment
of the welding can be made by adjusting the output
“CONTROL” or remote control. For the best arc
stability, always use setting that results in the highest
setting of the output or remote control and the lowest
setting of the “RANGE” switch.
The Ranger 9 can be used with a broad range of AC
and DC stick electrodes. See “Welding Tips 1”
included with the Ranger 9 for electrodes within the
rating of this unit and recommended welding currents
of each. See the following table for welding current
ranges:
CURRENT RANGES (AC and DC STICK WELDING
- 5 to 10 ON CONTROL DIAL)
TIG (Constant Current) Welding
The Ranger 9 can be used in a wide variety of AC
and DC Tungsten Inert Gas (TIG) welding applications
for AC TIG welding up to 200 amps and DC TIG
welding up to 250 amps.
The K930-1 TIG Module installed on a Ranger 9
provides high frequency and shielding gas control for
AC and DC GTAW (TIG) welding processes. The TIG
Module allows full range output control. Afterflow time
is adjustable from 0 to 55 seconds.
When using the Ranger 9 for AC TIG welding of
aluminum, the TIG Module is to be set for CONTINU-
OUS HF. The following settings and electrodes are
recommended:
When AC TIG welding, the actual maximum welding
current is 40 to 80 amps higher than the current
marked on the RANGE SWITCH dial. This is a result
of a lower effective reactance due to the natural rectifi-
cation that occurs with the AC TIG welding process.
Wire Feed (Constant Voltage) Welding
The Ranger 9 can be used with a broad range of flux-
cored wire (Innershield and Outershield) electrodes
and solid wires for MIG welding (gas metal arc
welding).
Some recommended Innershield electrodes are:
NR-211MP, NR-311, NR-203 series as well as,
Lincore® 33 and 55 hardfacing electrodes. Diameters
from .035 (0.9mm) up to and including 5/64” (2.0mm)
can be used. 5/64” (2.0mm) NS-3M can be used in
limited applications. Cable length and other condi-
tions can affect the ultimate results of this application.
Request Lincoln publication N-675 for additional infor-
mation.
