RECOMMENDED APPLICATIONS

WELDER
The RANGER 10-LX provides excellent constant cur-
rent AC/DC welding output for stick (SMAW) welding
and for TIG welding, and it offers constant voltage out-
put for DC semiautomatic wire feed welding. For more
details on using the machine as a welder, see Welding
Operation in the Operation section of this manual.
GENERATOR
The RANGER 10-LX gives AC generator output for
medium use demands.
ing the generator, see Auxiliary Power in the
Operation section of this manual.

RANGER 10-LX
• Top-mounted 10 gallon (38.0 litre) fuel tank with
convenient top fil.
• Front-panel mounted fuel gauge.
• Quiet engine muffler and insonorized case for
extremely quiet operation.
• All copper alternator windings and high quality insu-
lation for dependable long life.
• Automatic engine shutdown protection for low oil
pressure.
• Automatic engine idler goes to low idle 10 to 14
seconds after welding for greater fuel economy;
includes high idle switch.
• Standard Remote Control Receptacle provides
interface for Lincoln remote control accessories.
Both 6 pin and 14 pin amphenols are provided for
ease in hooking up wire feeders.
• Canadian Standard Association (CSA) approved
models available; include integrated generator out-
put overload protection through circuit breakers.

WELDING CAPABILITY

The RANGER 10-LX is rated 250 amps, 25 volts con-
stant current AC or 250 amps, 25 volts constant cur-
rent DC (250 amps 30 volts constant voltage DC) at
100% duty cycle on a ten-minute basis.
The current is continuously variable from 45 to 250
amps AC or 45 to 250 amps DC. The RANGER 10-LX
can weld with all 3/32 and most 1/8 inch and 1/16
diameter Lincoln AC stick electrodes.
processes using wire diameters from .030 to .068 inch
are possible, depending on the specific process and
wire feeder. (See LIMITATIONS.)

LIMITATIONS

• The RANGER 10-LX is not recommended for any
processes besides those that are normally per-
formed using stick welding (SMAW), TIG welding
(GTAW), MIG (GMAW) welding and Innershield
(FCAW) welding. Specific limitations on using the
RANGER 10-LX for these processes are described
in the Welding Operation section of this manual.
• The RANGER 10-LX is not recommended for pipe
thawing.
• During welding, generator power is limited and out-
put voltages can drop. Therefore, DO NOT OPER-
ATE ANY SENSITIVE ELECTRICAL EQUIPMENT
WHILE YOU ARE WELDING. See Table B.4 for per-
missible simultaneous welding and auxiliary power
loads.
