COOL ARC®26 Do not use!!
Pre-packaged welding industry coolants. These coolants may contain oil-
based substances, which attack the plastic components of the cooler.
Once added to the cooler, these substances are impossible to purge
from the water lines and heat exchanger.
Automotive anti-freeze. These coolants will damage the pump and block
of the heat exchanger, affecting cooling performance.

Electromagnetic Compatibility (EMC)
11/04
This machine has been designed in accordance with all relevant directives and standards. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommunications (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand this
section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.
Consider the following guidelines to reduce electromagnetic emissions from the machine.
Connect the machine to the input supply according to this manual. If disturbances occur if may be necessary to take
additional precautions such as filtering the input supply.
The output cables should be kept as short as possible and should be positioned together. If possible connect the
work piece to ground in order to reduce the electromagnetic emissions. The operator must check that connecting the
work piece to ground does not cause problems or unsafe operating conditions for personnel and equipment.
Shielding of cables in the work area can reduce electromagnetic emissions. This may be necessary for special
applications.
WARNING
The Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those locations,
due to conducted as well as radiated disturbances.

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.
ARTIFICIAL OPTICAL RADIATION: According with the requirements in 2006/25/EC Directive and
EN 12198 Standard, the equipment is a category 2. It makes mandatory the adoption of Personal
Protective Equipments (PPE) having filter with a protection degree up to a maximum of 15, as required
by EN169 Standard.
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 supplying power for welding operations carried out in
an environment with increased hazard of electric shock.
