TOWING
The recommended trailer for use with this equipment for road,
in-plant and yard towing by a vehicle
(1)
is Lincoln’s K957-1. If
the user adapts a non-Lincoln trailer, he must assume responsi-
bility 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 considered 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 weld-
ing equipment so there will be no undue stress to the frame-
work.
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 while being operated or ser-
viced.
4. Typical conditions of use, i.e., travel speed; roughness of
surface on which the trailer will be operated; environmental
conditions; like maintenance.
5. Conformance with federal, state and local laws.

PRE-OPERATION SERVICE
READ the engine operating and maintenance instruc-
tions supplied with this machine.
OIL
The Weldmark 225 is shipped with the engine crankcase
filled with SAE 10W-30 oil. 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. Make certain that the oil
filler cap is tightened securely. Refer to the engine
Owner’s Manual for specific oil recommendations.
FUEL
Fill the fuel tank with clean, fresh, lead-free gasoline.
Observe fuel gauge while filling to prevent overfilling.
BATTERY CONNECTIONS
This welder is shipped with the negative battery cable
disconnected. Make sure that the Engine Switch is in the
“STOP” position and attach the disconnected cable
securely to the negative battery terminal before attempt-
ing to operate the machine. If the battery is discharged
and does not have enough power to start the engine, see
the battery charging instructions in the Battery section.
WELDING OUTPUT CABLES
With the engine off, connect the electrode and work
cables to the studs provided. These connections should
be checked periodically and tightened if necessary.
Loose connections will result in overheating of the output
studs.
When welding at a considerable distance from the
welder, be sure you use ample size welding cables.
Listed below are copper cable sizes recommended for
the rated current and duty cycle. Lengths stipulated are
the distance from the welder to work and back to the
welder again. Cable sizes are increased for greater
lengths primarily for the purpose of minimizing cable volt-
age drop.

VEHICLE MOUNTING
Improperly mounted concentrated loads may
cause unstable vehicle handling and tires or other
components to fail.
• Only transport this Equipment on serviceable
vehicles which are rated and designed for such
loads.
• Distribute, balance and secure loads so vehicle
is stable under conditions of use.
• Do not exceed maximum rated loads for compo-
nents such as suspension, axles and tires.
• Use appropriate nuts bolts and lockwashers to
attach the equipment base to the metal bed or
frame of vehicle.
• Follow vehicle manufacturer’s instructions.
