Tig Process:
In TIG welding process, gas usage depends on cross-sectional area of the nozzle. For comonnly used torches:
Helium: 14-24 l/min
Argon: 7-16 l/min
Notice: Excessive flow rates causes turbulence in the gas stream which may aspirate atmospheric contamination into
the welding pool.
Notice: A cross wind or draft moving can disrupt the shielding gas coverage, in the interest of saving of protective gas
use screen to block air flow.

Electromagnetic Compatibility (EMC)
01/11
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.
This machine has been designed to operate in an industrial area. The operator must install and operate this
equipment as described in this manual. If any electromagnetic disturbances are detected the operator must
put in place corrective actions to eliminate these disturbances with, if necessary, assistance from Lincoln
Electric. This machine is not in accordance with IEC 61000-3-12. If it is powered by a low voltage public
distribution network in the connection responsibility of the installer or user of equipment, consultation, if necessary, with
the electricity service distributor.
Before installing the machine, the operator must check the work area for any devices that may malfunction because of
electromagnetic disturbances. Consider the following.
Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the
machine.
Radio and/or television transmitters and receivers. Computers or computer controlled equipment.
Safety and control equipment for industrial processes. Equipment for calibration and measurement.
Personal medical devices like pacemakers and hearing aids.
Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure
that all equipment in the area is compatible. This may require additional protection measures.
The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.
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 can be potential difficulties in ensuring electromagnetic compatibility in those locations,
due to conducted as well as radio-frequency disturbances.

death.
READ AND UNDERSTAND INSTRUCTIONS: Read and understand this manual before operating this
equipment. Plasma cutting or gouging 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.
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

Protective Equipments (PPE) having filter with a protection degree up to a maximum of 15, as required
by EN169 Standard.
WORK MATERIALS CAN BURN: Cutting 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.
EQUIPMENT WEIGHT OVER 30kg: Move this equipment with care and with the help of another
person. Lifting may be dangerous for your physical health.
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 torch, 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 cutting process including sparks and heat
sources.

Cutting sparks can cause explosion or fire. Keep
flammables away from cutting. Do not cut near
flammables. Have a fire extinguisher nearby, and have
a watch person ready to use it. Do not cut on drums or
any closed container.
The plasma arc can cause injury and burns. Keep your
body away from nozzle and plasma arc. Turn off
power before disassembling torch. Do not grip material
near cutting path. Wear complete body protection.
Electric shock from torch or wiring can kill. Wear dry
insulating gloves. Do not wear wet or damaged gloves.
Protect yourself from electric shock by insulating
yourself from work and ground. Disconnect input plug
or power before working on machine.
Breathing cutting fumes can be hazardous to your
health. Keep your head out of the fumes. Use forced
ventilation or local exhaust to remove the fumes. Use
ventilating fan to remove fumes.
Arc rays can burn eyes and injure skin. Wear hat and
safety glasses. Use ear protection and button shirt
collar. Use welding helmet with correct shade of filter.
Wear complete body protection.
Become trained and read the instructions before
working on the machine or cutting.
Do not remove or paint over (cover) the label.
SAFETY MARK: This equipment is suitable for supplying power for cutting 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
