Installation And Operator Instructions - Lincoln Electric INVERTEC V270 Bedienungsanleitung

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 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.
CAUTION: The high frequency used for contact-free ignition with TIG (GTAW) welding, can interfere
HF
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.

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 IP23S.
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
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: 35% duty cycle:
Welding for 3.5 minutes.
Refer to the Technical Specification section for more
information about the machine rated duty cycles.
Break for 6.5 minutes.
Input Supply Connection
Check the input voltage, phase, and frequency supplied
to this machine before turning it on. The allowable input
voltage is indicated in the technical specification section
of this manual and on the rating plate of the machine.
Be sure that the machine is grounded.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. The fuse rating and cable sizes are both
indicated in the "Technical Specification" section of this
manual.
The machines:
V205 2V: (230 / 400Vac, single phase)
V270: (400Vac, three phase)
V270 2V: (230 / 400Vac, three phase)
V405: (400Vac, three phase)
are designed to operate on engine driven generators as
long as the auxiliary can supply adequate voltage,
frequency and power as indicated in the "Technical
Specification" section of this manual. The auxiliary
supply of the generator must also meet the following
conditions:
Vac peak voltage: below 410V (for 230Vac input) or
720V (for 400Vac input).
Vac frequency: in the range of 50 and 60 Hertz.
RMS voltage of the AC waveform:
V270, V405:
V205 2V, V270 2V:
It is important to check these conditions because many
engine driven generators produce high voltage spikes.
Operation of this machine on engine driven generators
not conforming to these conditions is not recommended
and may damage the machine.
