Lincoln Electric IM571 RANGER 300 D and 300 DLX - Manual (Page 17)

B-2 OPERATION B-2
ADDITIONAL FEATURES
RANGER 300 D (K1522-1):
• One constant voltage wire-feed welding range - 80 to
200 amps.
The wire feed setting permits the Ranger 300D to be
used with the LN-25 Wire Feeder and .035, .045 or
.068 NR®-211-MP Innershield electrodes. Limited
MIG (GMAW) welding can also be done with .030 or
.035 L-50 & L-56 using blended Argon shielding gas.
“Auto-Idle” functions when using an LN-25 with an
internal contactor.
ADDITIONAL FEATURES
RANGER 300 DLX (K1522-2):
• Four constant voltage (CV) wire-feed welding
ranges with fine control on each range for welding at
40 to 300 amps.
• Excellent arc characteristics with MIG (GMAW) and
recommended Innershield electrodes (FCAW).
• Wire feeder amphenol receptacle (14 pin) for quick
connection of control cable.
• Voltmeter for reading CV wire-feed welding arc volt-
age.
• Built in contactor with front panel selection of "cold"
or "hot" welding terminals.
• Aluminum TIG welding when used with K930-1 TIG
Module. Output contactor control with Amptrol.
• Recommended wire feeders are the LN-25 with 42
Volt Remote Output Control Module or with internal
contactor and all models of the LN-7.
RECOMMENDED APPLICATIONS
WELDER
The RANGER 300 provides excellent constant current
AC/DC welding output for stick (SMAW) welding and
for TIG welding, and it offers constant voltage output
for DC semiautomatic wire feed welding.
GENERATOR
The RANGER 300 gives AC generator output for
medium use demands.
LIMITATIONS
• The Ranger 300 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.
• The RANGER 300 D/DLX 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
permissible simultaneous welding and auxiliary
power loads.
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.
Only qualified personnel should install, use, or service
this equipment.
CONTROLS AND SETTINGS
All generator/welder controls are located on the
Output Control Panel of the machine case front.
Diesel engine glow plug, idler control, and start/stop
controls are also on the case front. See Figure B.1
and the explanations that follow.
