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 supplying power for welding operations carried out in
an environment with increased hazard of electric shock.
A-2
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 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.
The welding transformer in the machine is protected
from overheating by a thermostat. When the machine is
overheated the output of the machine will turn “OFF“,
and the Thermal Indicator Light will turn “ON“. When the
machine has cooled to a safe temperature the Thermal
Indicator Light will go out and the machine may resume
normal operation. Note: For safety reasons the machine
will not come out of thermal shutdown if the trigger on
the welding gun has not been released.
Minutes or decrease
duty cycle
Input Supply Connection
Installation and mains outlet socket shall be made and
protected according to appropriate rules.
Check the input voltage, phase, and frequency supplied
to this machine before turning it on. Verify the
connection of grounding wires from the machine to the
input source. The allowable input voltages are 3x220V,
3x380V and 3x440V 50/60Hz (440V: factory default).
For more information about input supply refer to the
technical specification section of this manual and to the
rating plate of the machine.
If it is necessary to change the input voltage:
• The input cable must be disconnected from the
mains supply and the machine switched OFF.
• Remove the big side cover from the machine.
• Reconnect X6 and X7 according to the diagram
below:
• Replace the big side cover.
Make sure that the amount of mains power available
from the input supply is adequate for normal operation of
the machine. The necessary delayed fuse (or circuit
breaker with ”D” characteristic) and cable sizes are
indicated in the technical specification section of this
manual.
