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.

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.

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.

duty cycle

Input Supply Connection

Installation and mains outlet socket shall be made and

protected according to appropriate rules.

•

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.

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.

•

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.

For machines having the following CODE numbers:

•

Dirt and dust that can be drawn into the machine

should be kept to a minimum.

CODE 50135, 50137, 50139 and 50141: the

allowable input voltage is 3x400V 50/60Hz.

•

This machine has a protection rating of IP23. Keep

it dry when possible and do not place it on wet

ground or in puddles.

•

CODE 50136, 50138, 50140 and 50142: the

allowable input voltages are 3x230V and 3x400V

50/60Hz (400V: factory default).

•

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.

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 main supply voltage:

•

Do not operate in areas with an ambient

temperature greater than 40°C.

Ensure that the input cable must be disconnected

from the main supply and the machine switched

OFF.

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.

•

Remove the big side cover from the machine.

•

Reconnect X11 and X12 according to the diagram

below.

X12

35% duty cycle:

X11

400V

230V

Replace the big side cover.

•

Welding for 3.5 minutes.

Break for 6.5 minutes.

Make sure the amount of power available from the input

connection 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.

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.

Output Connections

Refer to points 8 and 10 of the images below.
