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 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
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 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 410V.
• The AC waveform frequency is between 50 and 60
hertz.
• The RMS voltage of the AC waveform is always
equal to 230Vac ± 10%.
BACK
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.
Output Connections
A quick disconnect system using Twist-Mate
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
approximately ¼ turn clockwise. Do not over tighten.
For V160-S machines, connect the gas hose from the
TIG torch to a gas regulator on the cylinder of gas to be
used.
For V160-T machines, connect the gas hose from the
TIG torch to the gas connector (B) on the front of the
machine. If necessary, an extra gas connector for the
fitting on the front of the machine is included in the
package. Next, connect the fitting on the back of the
machine to a gas regulator on the cylinder of gas to be
used. An input gas line and the required fittings are also
included in the package. Connect the TIG torch trigger
to the trigger connector (A) on the front of the machine.
Remote Control Connection
For V160-T machines only, refer to the accessories
section for a list of remote controls. If a remote control
is used, it will be connected to the remote connector (C)
on the front of the machine. The machine will
automatically detect the remote control, turn on the
TM
cable
