INSTRUCTION MANUAL FOR ARC WELDING MACHINE 

IMPORTANT 

1.2 SPECIFICATIONS 
 

 

Before using this device all people authorised to its use, repair 
or inspection, should read the book 

"Safety rules for using 

machines

" and the 

"Instruction manual"

 specific for every 

machine. Contact your distributor if you have not understood 
some instructions. 

This welding machine is a constant direct current generator, 
created by the INVERTER technology, designed for welding 
with coated electrodes and with the TIG procedure. 

For any requests of information, please always state the item 
and the serial number of the welding machine. 

It is also essential to pay special attention to the "SAFETY 
RULES" Manual. The symbols next to certain paragraphs 
indicate points requiring extra attention, practical advice or 
simple information. 

 

1.3 BEFORE CONNECTING THE WELDING MACHINE 

 
Before connecting and switching on the unit follow all safety 
rules and instructions as indicated in this manual. Make sure 
that the airflow on cooling slots is not obstructed and then 
proceed as follows: 

This MANUAL and the "SAFETY RULES" MANUAL must be 
stored carefully in a place familiar to everyone involved in 
using the machine. They must be consulted whenever doubts 
arise and be kept for the entire lifespan of the machine; they 
will also be used for ordering replacement parts. 

1)  unpack the machine 
2)  take care that the unit is not placed against a wall or in a 

position that might cut off the air; moreover, do not cover 
the unit's source with plastic materials, metal or paper 
sheets because they cause the decrease of the airflow, 

IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE 
FROM QUALIFIED PERSONNEL. 
 

1 GENERAL DESCRIPTIONS 

3)  make sure that the air temperature does not 40°C, 

 

4) do not place any filtering device over the intake air 

passages of this welding machine. 

1.1 EXPLANATION OF TECHNICAL SPECIFICATIONS 

Warranty is void if any type of filtering device is used. 

 

 

2 INSTALLATION 
 
2.1 CONNECTION TO MAINS SUPPLY 
 

Before connecting the unit to the mains make sure that supply 
voltage corresponds to the voltage indicated on the welding 
machine technical specification tag. 

 

 

IEC 60974  - 1 .......The welder is manufactured according to 

2.2 PROTECTION SYSTEM 

IEC 60974 - 10 

this international standards 

 

Cl. A.......................Machine for professional and industrial use 

The unit is equipped with internal protections, which assure a 
lasting proper operation. 

Art......................... Item  number, to be indicated for any 

request concerning the welding machine. 

These protective systems are the following: 

  Single-phase static frequency converter - 

transformer - rectifier. 

 
2.2.1 Electrode anti-sticking protection 

When the electrode sticks itself on the piece, the machine 
brings the I

2

 current to not dangerous values for the electrode. 

....................... Dropping characteristic. 

 

MMA.................... Suitable for manual welding with coated 

electrodes. 

2.2.2 Thermal protections 

The signal light 

B

 (picture 1) indicates the intervention of this 

protection. As soon as the unit has cooled down, it will be in 
working conditions again. Do not shut off the welding machine 
until the led has gone off. 

U

o

.........................

 

Secondary no - load voltage. 

X........................... Duty – cycle percentage. The duty-cycle 

expresses the percentage, calculated on 
10 minutes, in which the welding machine 
can operate at a determined current, 
without over-heating. 

OVER VOLTAGE CAN DAMAGE THE UNIT

 

 

I

2

........................... Welding current. 

2.2.3 Protection against incorrect supply voltages 

U

2

.......................... Secondary voltage with I welding current. 

If the voltage is greater than 270V when the switch 

K

 (pict. 1) 

is turned on, the yellow led 

B

 (pict. 1) will flash briefly twice, 

with a brief pause between flashes, and the machine will not 
deliver current. 

U .......................... Nominal supply voltage. 

1

1 ~ 50/60Hz..........  Single - phase supply 50 or 60 Hz. 
I

1

 max. …………...  This is the maximum value of the absorbed 

current 

In this situation the electric circuits are protected, but the fan 
may burn out after a few minutes. 

I

1

 eff...................... This is the maximum value of the actual 

current absorbed, considering the duty 
cycle. 

In the voltage low during welding, the yellow led 

B

 (pict. 1) 

flashes every 0.5 seconds and the machine does not deliver 
current. 

IP23...................... Grade of protection of frame. Grade 3 as a 

second number means that this unit is fit to 
work outside under the rain. 

 
2.2.4 Motor-driven generators 

....................…….. Symbol meaning that the welding machine 

can be used in high electric shock risk-
working areas. 

They must have an electronic regulator of the tension, a power 
equal to or greater than 6kVA and must not deliver a voltage 
greater than 260V. 

NOTES:................ In addition, the welding machine has been 

designed to work in areas with grade 3 of 
pollution.(See IEC 664).
