Installation and Operator Instructions
General description
CITOTIG 315 AC/DC machine is designated to performe
SMAW and GTAW welding process in DC and AC
current.
Unit is designed mainly to satisfy GTAW requestes in
both DC and AC mode: thanks an advance menu
options both beginners and experts welder can adjust
welding parameters to
performances.
Following paragraphs will show how to access to the
menu and the parameters tha can be set.
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 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.
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 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.
auxiliary supply of the generator must also meet the
following conditions:

have the best welding
The
400Vac 3 phases:

Vac peak voltage: below 670V

Vac frequency: in the range of 50 and 60Hz

RMS voltage of the AC waveform: 400Vac ± 15%
230Vac 3 phases:

Vac peak voltage: below 410V

Vac frequency: in the range of 50 and 60Hz

RMS voltage of the AC waveform: 230Vac ± 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-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)
This machine does not include a MMA welding kit
cables, but may be purchased separately. Refer to the
accessories section for more information.
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.
Shown here is the connection method for torch.
Connect the electrode cable to the torch terminal and the
work clamp to the work piece terminal.
