Installation And Operator Instructions - Lincoln Electric INVERTEC V160 Manuel D'utilisation

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.
•
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.
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.
Verify the connection of grounding wires from the
machine to the input source.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. The necessary fuse and cable sizes are
indicated in the technical specification section of this
manual.
This machine is designed to operate on engine driven
generators as long as the 230Vac (or 115Vac for V160
2V) auxiliary can supply adequate power as indicated in
the technical specification section of this manual. The
auxiliary supply of the generator must also meet the
following conditions:
•
The AC waveform peak voltage is below 205V (for
115Vac input) or 410V (for 230Vac input).
•
The AC waveform frequency is between 50 and 60
hertz.
•
The RMS voltage of the AC waveform is always
equal to:
For V160:
For V160 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.
The V160 2V has an internal fuse placed on the input
power circuit for prevention of internal damages. This
fuse limits the current absorbed from the input supply.
Output Connections
A quick disconnect system
using Twist-Mate™ cable
plugs is used for the
welding cable connections.
Refer to the following
sections for more
information on connecting
the machine for operation
of stick welding (MMA) or
TIG welding (GTAW).
Stick Welding (MMA)
First determine the proper
electrode polarity for the
electrode to be used.
Consult the electrode data
for this information. Then
connect the output cables to the output terminals of the
machine for the selected polarity. For example, if DC(+)
welding will be used then connect the electrode cable to
the (+) terminal of the machine and the work clamp to
the (-) terminal. Insert the connector with the key lining
up with the keyway and rotate approximately ¼ turn
clockwise. Do not over tighten.
For DC(-) welding switch the cable connections at the
machine so that the electrode cable is connected to (-)
and the work clamp is connected to (+).
TIG Welding (GTAW)
This machine does not include a TIG torch necessary for
TIG welding, but one may be purchased separately.
Refer to the accessories section for more information.
Most TIG welding is done with DC(-) polarity; connect
the torch cable to the (-) terminal of the machine and the
work clamp to the (+) terminal. Insert the connector with
the key lining up with the keyway and rotate
