Installation And Operator Instructions - Lincoln Electric INVERTEC V160-T Operator's Manual

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.
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:
•
V160: (230Vac, single phase)
• V160 2V: (115 / 230Vac, single 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 205V (for 115Vac input) or
410V (for 230Vac input).
•
Vac frequency: in the range of 50 and 60 Hertz.
•
RMS voltage of the AC waveform:
V160:
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.
ARFU (Auto-Restore FUse)
The dual input voltage machine is provided with the
ARFU device. It operates only when the input is
connected to the 115Vac mains and protects from input
overcurrent. When active, the "Power LED" blinks (see
"Controls and Operational Features" section).
Note: The ARFU device operates independently from
the machine's duty-cycle.
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
