Installation And Operator Instructions - Lincoln Electric INVERTEC 160SX Operator's Manual

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.
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.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in an
environment with increased hazard of electric shock.
The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time

Installation and Operator Instructions

Read this entire section before installation or operation
of the machine.
Location and Environment
This machine can 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.

Input Supply Connection
®
The Invertec 160SX is a wide input voltage range:
before installing and turning it on, check the supplied
input voltage, phase, and frequency. The allowable input
voltage range, phase, and frequency are indicated in the
technical specification section of this manual and on the
machine's rating plate. Be sure that the machine is
grounded.
Make sure the power available at 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.
Input Supply From Engine Driven Generators
The machine is 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.

Vac frequency: in the range of 50 and 60Hz.

RMS voltage of the AC waveform: from 115V to
230V ± 15%.
It is important to check these conditions because many
engine driven generators produce high voltage spikes.
Operation of this machine with engine driven generators
not conforming to these conditions is not recommended
and may damage the machine.
