CE COMPLIANCE: This equipment complies to the European Communities directives.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in
an environment with increased hazard of electric shock.

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 400Vac 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 720V.
• The AC waveform frequency is between 50 and 60
hertz.
• The RMS voltage of the AC waveform is always
equal to 400Vac ± 15%.
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-MateTM 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
approximately ¼ turn clockwise. Do not over tighten.
For V270-S machines, connect the gas hose from the
TIG torch to a gas regulator on the cylinder of gas to be
used.
