Safety 11/04
WARNING
This equipment must be used by qualified personnel. Be sure that all installation, operation, maintenance and repair
procedures are performed only by qualified person. Read and understand this manual before operating this equipment.
Failure to follow the instructions in this manual could cause serious personal injury, loss of life, or damage to this
equipment. Read and understand the following explanations of the warning symbols. Lincoln Electric is not responsible
for damages caused by improper installation, improper care or abnormal operation.
WARNING: This symbol indicates that instructions must be followed to avoid serious personal injury,
loss of life, or damage to this equipment. Protect yourself and others from possible serious injury or
death.
READ AND UNDERSTAND INSTRUCTIONS: Read and understand this manual before operating
this equipment. Arc welding can be hazardous. Failure to follow the instructions in this manual could
cause serious personal injury, loss of life, or damage to this equipment.
ELECTRIC SHOCK CAN KILL: Welding equipment generates high voltages. Do not touch the
electrode, work clamp, or connected work pieces when this equipment is on. Insulate yourself from
the electrode, work clamp, and connected work pieces.
ELECTRICALLY POWERED EQUIPMENT: Turn off input power using the disconnect switch at the
fuse box before working on this equipment. Ground this equipment in accordance with local electrical
regulations.
ELECTRICALLY POWERED EQUIPMENT: Regularly inspect the input, electrode, and work clamp
cables. If any insulation damage exists replace the cable immediately. Do not place the electrode
holder directly on the welding table or any other surface in contact with the work clamp to avoid the
risk of accidental arc ignition.
ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS: Electric current flowing through any
conductor creates electric and magnetic fields (EMF). EMF fields may interfere with some
pacemakers, and welders having a pacemaker shall consult their physician before operating this
equipment.
CE COMPLIANCE: This equipment complies with the European Community Directives.
FUMES AND GASES CAN BE DANGEROUS: Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases. To avoid these dangers the operator must use
enough ventilation or exhaust to keep fumes and gases away from the breathing zone.
ARC RAYS CAN BURN: Use a shield with the proper filter and cover plates to protect your eyes from
sparks and the rays of the arc when welding or observing. Use suitable clothing made from durable
flame-resistant material to protect you skin and that of your helpers. Protect other nearby personnel
with suitable, non-flammable screening and warn them not to watch the arc nor expose themselves to
the arc.
WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION: Remove fire hazards from the welding
area and have a fire extinguisher readily available. Welding sparks and hot materials from the welding
process can easily go through small cracks and openings to adjacent areas. Do not weld on any
tanks, drums, containers, or material until the proper steps have been taken to insure that no
flammable or toxic vapors will be present. Never operate this equipment when flammable gases,
vapors or liquid combustibles are present.
WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and
materials in work area can cause serious burns. Use gloves and pliers when touching or moving
materials in the work area.
SAFETY MARK: This equipment is suitable for welding operations carried out in an environment with
increased hazard of electric shock.

CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Location and Environment
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.
•Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.
•Do not use this machine for pipe thawing.
•This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when
switched on.
•Dirt and dust that can be drawn into the machine
should be kept to a minimum.
•This machine has a protection rating of IP23. Keep
it dry when possible and do not place it on wet
ground or in puddles.
•Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility
in this manual.
•Do not operate in areas with an ambient
temperature greater than 40°C.
Duty cycle
The duty cycle of a welding machine is the percentage
of time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% duty cycle:
Welding for 6 minutes.
Break for 4 minutes.
Refer to the Technical Specification section for more
information about the machine rated duty cycles.
Input Supply Connection
Check the input voltage, phase, and frequency of the
power source that will be connected to this wire feeder.
The allowable input voltage of the power source is
indicated on the rating plate of the wire feeder. Verify
the connection of grounding wires from the power
source to the input source.
Gas Connection
A gas cylinder must to be installed with a proper flow
regulator. Once a gas cylinder with a flow regulator has
been securely installed, connect the gas hose from the
regulator to the machine gas inlet connector. Refer to
point 8 of the images below. The wire feeder supports
all suitable shielding gases including carbon dioxide,
argon and helium at a maximum pressure of 5,0 bar.
The Linc Feed also includes an internal gas flow
regulator, showed at point 11 of the images below.
Output Connections
Refer to item 3 of the images below.

recommended cooling liquid and flow rates.
8. Gas Connector: Connection for gas line.
9. Wire Drive: 4-Roll wire drive compatible with
37mm drive rolls.
10. Cold Inch / Gas Purge Control: This switch allows
gas flow or wire feeding without turning on output
voltage.
11. Gas Flow Regulator: Regulate flow between 0-25
LPM (liter/min.).
12. Wire Spool Support: Maximum 15kg spools.

spindle. Also accepts Readi-Reeltype spools onto
included spindle adapter.
WARNING
The Linc Feed wire feeders must be used with the door
completely closed during welding.
Maintenance
WARNING
For any maintenance or repair operations it is
recommended to contact the nearest Technical Service
Center or Lincoln Electric. Maintenance or repairs
performed by unauthorized service centers or
personnel will null and void the manufacturer's
warranty.
The frequency of the maintenance operations may vary
in accordance with the working environment where the
machine is placed.
Any noticeable damage should be reported
immediately.
Routine maintenance
•Check condition of insulation and connections of
the work cables and input power supply cable.
•Remove the spatters from the welding gun nozzle.
Spatters could interfere with the shielding gas flow
to the arc.
•Check the welding gun condition: replace it, if
necessary.
•Check condition and operation of the cooling fan.
Keep clean its airflow slots.
Periodic maintenance
Perform the routine maintenance and, in addition:
•Keep the machine clean. Using a dry (and low
pressure) airflow, remove the dust from the
external case and from the cabinet inside.
•Check condition of all connections and change if
necessary.
•Check and tighten all screws.
WARNING
Mains supply network must be disconnected from the
machine before each maintenance and service. After
each repair, perform proper tests to ensure safety.
