HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary.
As a rule of thumb, derate the welder output 5% for
every 500 meters (1640 ft.) above 1000 meters (3280
ft.).
Contact a Perkins Service Representative for any
engine adjustments that may be required for high alti-
tude operation.
TOWING
The recommended trailers for use with this equipment
for in-plant and yard towing by a vehicle
(1)
are Lincoln’s
K767-1, K956-1 and K956-2. The K956-1 and K956-2
are also designed to be used at highway speeds
(1) .If the
user adapts a non-Lincoln trailer, he must assume
responsibility that the method of attachment and usage
does not result in a safety hazard nor damage the
welding equipment. Some of the factors to be consid-
ered are as follows:
1. Design capacity of trailer vs. weight of Lincoln
equipment and likely additional attachments.
2. Proper support of, and attachment to, the base of
the welding equipment so that there will be no
undue stress to the trailer’s framework.
3. Proper placement of the equipment on the trailer to
insure stability side to side and front to back when
being moved and when standing by itself.
4. Typical conditions of use, such as travel speed,
roughness of surface on which the trailer will be
operated, and environmental conditions.
5. Proper preventative maintenance of trailer.
6. Conformance with federal, state and local laws. 1

For highway use, consult applicable federal, state
and local laws regarding specific requirements for
use on public highways, such as brakes, lights, fend-
ers, etc.
PRE-OPERATION ENGINE AND
COMPRESSOR SERVICE
READ the engine and compressor operating and main-
tenance instructions supplied with this machine.
ENGINE OIL
The WELD’N AIR is shipped with the engine crankcase
filled with high quality SAE 10W-30 oil (API class CD or
better). Check the oil level before starting the engine. If it
is not up to the full mark on the dip stick, add oil as
required. Check the oil level every four hours of running
time during the first 35 running hours. Refer to the engine
Operator’s Manual for specific oil recommendations and
break-in information. The oil change interval is dependent
on the quality of the oil and the operating environment.
Refer to the engine Operator’s Manual for the proper ser-
vice and maintenance intervals.
AIR COMPRESSOR OIL
The WELD’N AIR is shipped with the compressor filled
with a high quality synthetic compressor oil. If oil is
needed add only Iowa Mold Tooling Co., Inc. (IMT) syn-
thetic compressor oil until compressor is full.
The use of any other oil causes excessive carbon build
up, and will void the warranty on the compressor.
------------------------------------------------------------------------
Check the oil level daily. Refer to the compressor
Operator’s Manual for the proper service and mainte-
nance intervals.
FUEL USE DIESEL FUEL ONLY
•Stop engine and allow to cool before
fueling.
•Do not smoke when fueling.
•Fill fuel tank at a moderate rate and do
not overfill.
•Wipe up spilled fuel and allow fumes to
clear before starting engine.
•Keep sparks and flame away from
tank.
------------------------------------------------------------------------
Fill the fuel tank with clean, fresh diesel fuel. The capac-
ity of the fuel tank is 22.5 gallons (85.1 liters). See engine
Operator’s Manual for specific fuel recommendations.
NOTE: Before starting the engine, be sure the fuel shut-
off valve on the sediment bowl is open by turning the han-
dle counterclockwise.
