Lincoln Electric LINC FEED 24M PRO Manual De Instrucciones página 5

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.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
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 (on front panel of wire feeder) 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.

Break for 4 minutes.
Input Supply Connection
Check the input voltage, phase, and frequency of the
power source that will be connected to this wire feeder.
The allowable input voltage of the power source is
indicated on the rating plate of the wire feeder. Verify
the connection of grounding wires from the power source
to the input source.
Gas Connection
A gas cylinder must be installed with a proper flow
regulator. Once a gas cylinder with a flow regulator has
been securely installed, connect the gas hose from the
regulator to the machine gas inlet connector. Refer to
point [8] of the images below. The wire feeder supports
all suitable shielding gases including carbon dioxide,
argon and helium at a maximum pressure of 5,0 bar.
Output Connections
Refer to point [1] of the images below.
Controls and Operational Features
1. EURO Socket: For connecting welding torch.
2. WFS (Wire Feed Speed) Control Knob: It enables
continuous control of wire feeding speed in the
range from 1.0 to 20m/min with manual mode or
correction of the speed automatically matched by
the machine in the range ±50% at synergic mode.
Before welding beginning and during Cold Inch
Switch using the Wire Feed Slow Run Control Knob
[12] has also an influence on the wire feeding
speed.
