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.

English English

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.

Controls and Operational Features

1. Water Connectors: Connections for water cooled

torches.

Warm water from torch.

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.

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.
