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.
WARNING
Provided that the public low voltage system impedance at the point of common coupling is lower than:
 56,4 mΩ for the POWERTEC i380C ADVANCED;
 23 mΩ for the POWERTEC i450C ADVANCED.
This equipment is compliant with IEC 61000-3-11 and IEC-3-12 and can be connected to public low voltage systems. It is
the responsibility of the installer or user of the equipment to ensure, by consultation with the distribution network operator if
necessary, that the system impedance complies with the impedance restrictions.
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
While a high electromagnetic field occurs, a welding current can fluctuate.

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.

English 5 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.
MOVING PARTS ARE DANGEROUS: There are moving mechanical parts in this machine, which can
cause serious injury. Keep your hands, body and clothing away from those parts during machine
starting, operating and servicing.
HOT COOLANT CAN BURN SKIN: Always be sure coolant is NOT HOT before servicing the cooler.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in
an environment with increased hazard of electric shock.
The manufacturer reserves the Right to make changes and/or improvements in design without upgrade at the same time
the operator’s manual.

and POWERTEC i450C ADVANCED enables welding:
 GMAW (MIG/MAG),
 FCAW (Flux-Cored),
 SMAW (MMA),
The following equipment has been added to
POWERTEC i380C ADVANCED and

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 and Overheating
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.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
