GX 271 Chopper
B-2
OPERATION
B-2
• One 50 amp 120/240 V AC, single phase power,
dual voltage receptacle with two 35 amp circuit
breakers. Supplies up to 33 amps of 240 V AC and
up to 66 amps of 120 V AC single phase auxiliary
power per side to separate branch circuits (not in
parallel). Allows easy connection to premises wiring.
• Welding and AC auxiliary power at the same time
(within machine total capacity).
OTHER FEATURES
• Overhead valve, V-twin, 20 HP gasoline engine.
Designed for long life, easy maintenance and excel-
lent fuel economy.
• Engine protection system shuts the engine down
with low oil pressure.
• Large maintenance-free battery. Group 58 with 435
cold cranking amps.
• Battery charging ammeter.
• Engine hour meter.
• Extended range 9 U.S. gallon (7.5 Imp. Gal., 34
liters) fuel tank.
• Automatic idler reduces engine speed when not
welding or drawing auxiliary power. This feature
reduces fuel consumption and extends engine life.
• Compact size fits crosswise in compact size pick-up
truck.
• Copper alternator windings for dependability and
long life.
• CSA approved.
RECOMMENDED APPLICATIONS
WELDER
The GX-271 provides excellent constant current 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 GX-271 gives AC power output for medium use
demands.
LIMITATIONS
• The GX-271 is not recommended for any process-
es besides those that are normally performed using
stick welding (SMAW), TIG welding (GTAW), MIG
(GMAW) welding and Innershield® (FCAW) welding.
• The GX-271 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.
