DESCRIPTION
Thank you for choosing this machine! To get the best use from your machine please read the following carefully.
The TIG 250 AC/DC is a portable, single phase, ventilated Inverter welding unit to be used with non consumable
electrode (TIG) in direct (DC) or alternative (AC) current. TIG welding requires a gas shield protection of
pure(Argon). In MMA mode, it allows you to weld with any kind of electrodes: rutile, basic, stainless steel or cast
iron.
The TIG 250 AC/DC can be equipped with a remote control or foot pedal.
The TIG 250 AC/DC has an integrated liquid cooling system to connect liquid cooled torches.
POWER SUPPLY – STARTING UP
• This machine is delivered with a 5 pin three-phase plug (3P + N + PE) 400V 16A type CEE17. The TIG 250 AC/DC
must be connected to a 400 V socket (50 - 60 Hz) WITH earth protected by a 16A circuit breaker and a 30mA
overcurrent discontactor.
The absorbed current (I1eff) is indicated on the device, for its maximum setting.
Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with the
current needed by the machine. In some countries, it may be necessary to change the plug to allow the
use at maximum settings.
This unit has an internal cooling liquid system which has 2 main functions: the cooling of the water torch if
connected and the cooling of internal spare parts. So the tank of the unit needs to be filled to the maximum line
indicated at the back of the machine.
•
The starting up is made by pushing on the standby button.
•
The device turns into protection mode if the power supply tension is under 360V or over 440V or if a
phase is missing. To indicate this default, the screen displays. Once in protection mode, you have to
unplug the device and plug it back into a socket delivering the correct voltage (see the table of error
messages).
• Fan: in MMA mode, the fan works nonstop. In TIG mode, the fan works only when welding, then stops after
cooling.
•
These are Class A devices. They are designed to be used in an industrial or professional environment. In a
different environment, it can be difficult to ensure electromagnetic compatibility due to conducted
disturbances as well as radiation
. They comply with the norm CEI 61000-3-12.

CONTROL BOARD (IHM) (FIG-2)
The control board is made of a colour TFT screen and two potentiometers. How it works in 3 states:
State 1 or Standby mode: with the potentiometer 1 you will be able to set the welding current, and with the
potentiometer 2 the parameters related to the welding current.
State 2 or Welding mode: by pushing the potentiometer 1 you will have access to the top menu. Then by turning the
button you will select the welding mode. You will exit this menu by waiting 8s or by pushing the potentiometer 2 ->
back to State 1.
State 3 or Welding parameters mode: by pushing the potentiometer 2 you will have access to the welding
parameters and you will see the selection by turning the button. You will exit this menu by waiting 8s or by pushing
the potentiometer 2 -> back to State 1.
