1 INTRODUCTION
IMPORTANT!
This handbook must be consigned to the user prior to installation and commissioning of the unit.
Read the "General prescriptions for use" handbook supplied separately from this handbook before
installing and commissioning the unit.
The meaning of the symbols in this manual and the associated precautionary information are given in
the "General prescriptions for use”.
If the "General prescriptions for use" are not present, it is mandatory to request a replacement copy
from the manufacturer or from your dealer.
Retain these documents for future consultation.

1.1 PRESENTATION
Multi Power 204T is an inverter DC TIG/MMA portable welding power source.
The sturdiness of the components of this unit makes it a reliable working companion for workshop and
outdoor applications.
The available DC TIG functions and digital control make this unit ideal for maintenance, building con-
struction, and light metalwork.
In MMA welding the Hot Start and Arc Force functions are adjustable and they allow improved arc strik-
ing, a atter bead and more uniform weld.
The Anti Sticking function makes it possible to detach the electrode rapidly from the workpiece in the
event of accidental sticking.
Up to 4,00mm diameter electrode welding is possible in MMA.
The power source is designed to guarantee safety and exibility through the following features:
OVERCUT: in case of over-voltage in the supply line, the supply to the power source is cut o󰀨.
The overcut protection protects electronic parts of the machine against damage caused by voltage
surges.
CURRENT AUTO-CALIBRATION: the power source works at a supply voltage ranging between
115V~±15%/50-60Hz and 230V~±15%/50-60Hz.
The maximum value of the adjustable welding current is automatically limited based on the supply volt-
age measured when the power source is switched on.
DERATING: Derating limits current during welding when supply voltage drops below the limit value of
190Vac.
This limits current input so as not to overload the inverter and keeps the welding arc stable.
FANS: Fan speed varies based on power source internal temperature measured by thermal sensors.
This function brings the following improvements:
- reduction of noise.
- reduction of dust extracted (cleaner equipment, less maintenance).
The welding modes and procedures available are those indicated in the table.

The reset procedure is useful in the following cases:
- Too many changes made to the welding parameters so user nds it di󰀩cult to restore defaults.
- Unidentied software problems that prevent the welding power source from functioning correctly.

- Coo [COOLER ACTIVATION GROUP]
○ ON= The cooler is always running when the power source is switched on. This mode is preferable
for heavy duty and automatic welding procedures.
○ OFF= The cooler is always disabled because an air-cooled torch is in use.
○ AUT= When the unit is switched on the cooler is switched on for 15s. During welding procedures
the cooler runs constantly. When welding is terminated the cooler continues to run for 90s + a
number of seconds equivalent to the average current value shown using the HOLD function.
- St.C. [STARTING CURRENT]
○ The value of this parameter can be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
F.Cu. [FINAL CURRENT]
○ The value of this parameter can be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
- HF.C. [HF CURRENT]
○ This parameter establishes the current value during HF discharge. The value of this parameter
can be set as an absolute value or in SYN.
○ With SYN setting the HF current value is calculated automatically on the basis of the preset weld-
ing current value.
Consequences of a higher value:
• Arc striking is facilitated, even on very dirty workpieces.
• Risk of piercing excessively thin gauge workpieces.
- PUL. [TYPE OF PULSED CURRENT]
○ SLo. = This setting enables slow pulsed mode. The peak time and Base time are set.
○ FA.= This setting enables fast pulsed mode. The frequency and duty-cycle are set.
- P.A. [PILOT ARC]
○ The function enables the output of a low current between the 1st and 2nd times of the torch trig-
ger to shield the mask in advance and avoid the risk of blinding ashback caused by the welding
current.
-StS [SPECIAL TORCH STROKE]
○The parameter changes the torch trigger operating mode.
○ oFF: indicates standard operation.
○1: species the 4T B-level management variant. Allows the transition to the secondary welding cur-
rent by pressing and holding down the UP or DOWN button; when the button is released, the primary
current is restored. With variant oFF selected, the UP/DOWN buttons are disabled for all procedures.
○ 2: species the down slope management variant. By releasing the torch trigger during the third
stroke (3S) the down slope is stopped and the nal current is immediately delivered without ha-
ving to go through the entire slope time.
-rHF [RESTART HF]
○This parameter changes the HF arc striking operation in the HF 4 stroke torch button mode. When
set to “oFF”, the automatic HF arc striking discharge is disabled when the long arc welding mode is
exited; to restart the welding operation, the torch trigger must be pressed again. When set to “on”
and the long arc welding mode is exited, the HF discharge is automatically started as soon as the
torch electrode approaches the workpiece. Disabling the automatic striking is useful to prevent the
accidental arc striking when the torch touches a part connected to the equipment earth (such as the
welding table) after exiting the long arc welding mode.

6.1 TORCH LOADING
WARNING!
Make sure the torch in use is correctly sized in relation to the welding current required and for the
available and selected cooling type. This prevents the risk of burns to which the operator is potentially
exposed, potential faults, and irreversible damage to the torch and the system.
If a torch is installed or replaced while the unit is running, the circuit of the newly installed torch must
be lled with coolant to avoid the risk of damage to the torch in the case of high voltage arc strikes
without any liquid in the circuit.
Power-up with operation of the cooler set to “ON” or “AUT” mode
○A check is performed automatically of the presence of liquid in the cooling circuit and the cooler
is switched on for 15 seconds.
○ If the coolant circuit is full, the power source sets up in the most recent stable welding congura-
tion.
○ If the coolant circuit is not full, all functions are inhibited and there will be no output power present.
AL. Coo. : The message appears on the following displays: D1.
Press any button to repeat the checking procedure for an additional 15seconds.
If the problem persists, rectify the cause of the alarm.
Power-up with operation of the cooler set to “OFF”
Operation of the cooler and the cooler alarm are disabled.
Welding is performed without liquid cooling of the torch.
Torch change-over with operation of the cooler set to “ON”
Press and release the torch trigger.
This serves to start the cooler for 15 seconds to ll the torch cooling circuit.

MESSAGE MEANING EVENT CHECKS
Al.C.
Cooler alarm
Indicates insu󰀩cient pressure in
the torch liquid cooling circuit.
All functions disabled.
Exceptions:
• Cooling fan.
The alarm message persists on
the display until the rst operation
is performed on the user interface.
• Cooler “ON”: the alarm is signal-
led as long as the unit alarm is
active and the cooler presence
signal persists.
• Cooler “OFF”: the alarm is ne-
ver signalled, irrespective of the
circumstances.
• Cooler “AUT”: the alarm is si-
gnalled at the times in which the
unit is running; the alarm signal
occurs as long as the unit pre-
sence signal persists.
• Check that the connection to
the cooler is correct.
• Check that the O/I switch is set
to I and that it illuminates when
the pump is running.
• Check that the cooler is lled
with coolant.
• Check that the cooling circuit
is liquid tight, notably the torch
hoses and the internal connec-
tions of the cooler.

8 DERATING
Derating is a machine function that cannot be selected by the user.
Derating limits the maximum welding current if the supply voltage drops below 190Vac.
For example, if the power source is set to weld with a current of 175A, that current will be the power
source output until the supply voltage will range between 184Vac and 230Vac.
If voltage drops to 165Vac, the power source automatic output current will be 160A.
The following diagram displays the maximum output current, based on the voltage supplied to the po-
wer source.
