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.
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.
HF
CAUTION: The high frequency used for contact-free ignition with TIG (GTAW) welding, can interfere
with the operation of insufficiently shielded computer equipment, EDP centers and industrial robots,
even causing complete system breakdown. TIG (GTAW) welding may interfere with electronic
telephone networks and with radio and TV reception.
EQUIPMENT WEIGHT OVER 30kg: Move this equipment with care and with the help of another
person. Lifting may be dangerous for your physical health.
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

Installation and Operator Instructions
General Description
The LADI box is an analog-digital communication
interface which allows to use the ArcLink®(5P) power
feeders with the analog (14P) power sources.
Read this entire section before installation or operation
of the machine.
Controls and Operational Features
Figure 1
1. Status Light: A two color light that indicates
system errors. Normal operation is steady
green light. Error conditions are indicated, per
Table 1.
NOTE: The status light will flash green, and
sometimes red and green, for up to one minute
when the machine is first turned on. When the
power source is powered it can take as long as 60
seconds for the machine to be ready to weld. This is
a normal situation as the machine goes through
initialization.
Table 1
LED Light
Condition
Meaning
Only machines which using ArcLink®
protocol for communication
Steady Green System OK. Power source is
operational, and is communicating
normally with all healthy peripheral
equipment.
Blinking Green Occurs during power up or a system
reset, and indicates the power source
is mapping (identifying)
each component in the system.
Normal for first 1-10 seconds after
power is turned on, or if the system
configuration is changed during
operation.
Alternating Green
and Red
If the status lights are flashing any
combination of red and green, errors
are present in the power source.
Individual code digits are flashed in
red with a long pause between digits.
If more than one code is present, the
codes will be separated by green
light. Read the error code before the
machine is turned off. If occurs, to
clear the error try to turn Off the
machine, wait for a few seconds,
then turn ON again. If the error
remains, a maintenance is required.
Please contact the nearest
authorized technical service center or
Lincoln Electric and report the error
code read.
Steady Red Indicate no communication between
the power source and device which
has been connected to this power
source.
2. Feeder Control Connection: 5 pins receptacle
for wire feeder. To communication wire feeder
with power source is used ArcLink®protocol.
3. Welding Output Socket: Allows the
connection, with the power cable, to the wire
feeder.
4. Welding Input Cable: Allows the connection
to the power source.
5. Control Input Cable: 14-pins connection. To
communication LADI with power source is
used analog control.

6. Mounting holes: Allows the fastening, with 4
screws (M5x20), to the power source. Use the
attached drill mask (R-0010-599-1) to position
LADI on the power source.
7. USB Receptacle: Allows the connection, with
USB cable (A-A type), to the personal
computer. The USB port is used for the
software upgrades of LADI or ArcLink® wire
feeder.
