ELECTRIC AND MAGNETIC FIELDS - May be dangerous.

· Electric current following through any con-

ductor causes localized Electric and Mag-

netic Fields (EMF). Welding/cutting current

creates EMF elds around cables and pow-

er sources.

 The magnetic elds created b high currents ma affect

the operation of pacemakers. Wearers of vital electronic

equipment (pacemakers) shall consult their physician be-

fore beginning any arc welding, cutting, gouging or spot

welding operations.

 Exposure to EMF elds in welding/cutting ma have oth-

er health effects which are now not known.

· All operators should use the followingprocedures in or-

der to minimize exposure to EMF elds from the welding/

cutting circuit:

- Route the electrode and work cables together

- Secure them with tape when possible.

- Never coil the electrode/torch lead around your body.

- Do not place your body between the electrode/torch

lead and work cables. If the electrode/torch lead

cable is on your right side, the work cable should also

be on your right side.

- Connect the work cable to the workpiece as close as

possible to the area being welded/cut.

- Do not work next to welding/cutting power source.

T1 process key.

With a long pressure of this key, LEDs L1 or L2 are

alternatively chosen.

LED L1 (TIG) LED L2 (MMA)

With a short pressure of this key, LEDs L35 or L36 are

alternatively chosen.

LED L35 (DC) LED L36 (AC)

2 LEDs will be always selected: one between LED L1 and

L2 and one between LED L35 and L36.

T2 program key.

One of the LEDs L3, L4, L5, L6 or L7 lights when

selected.

LED L3 - (manual) spot welding.

After selecting the welding current (LED L28) and the spot

welding time (LED L34) using key T8, set the values using

the knob M1.

This welding mode can only be selected in start-up mode

with HF (LED L9). The operator presses the torch trigger,

the arc lights and shuts off automatically after the pre-set

spot welding time. In order to weld the following spot, it is

necessary to release the torch trigger and press it again.

Range from 0.1 to 30 s.

To obtain points in sequence split up by intervals, the

item “tin” (time interval) is available from the second

functions menu; this item is displayed only if spot

welding is selected.

To activate the function proceed as follows:

1. Press keys T7 and T8 at the same time to enter the

“Second Functions” menu.

2. Brie press ke T8 until the display D1 shows the

abbreviation "tin". The display D2 will show the word

"OFF".

3. Turn knob M1 to select the time interval. Range from 0.1

to 25 s.

4. Press keys T7 and T8 at the same time to return to

normal display.

LED L4 - 2-stage TIG welding (manual).

B pressing the torch trigger the current moves to rst

level (LED L23) and remains there for the time previously

regulated and displayed by the LED L24 before reaching

the welding current in the “slope-up” time indicated by the

LED L25 the reaching of the welding current is indicated

by the start-up of the LED L28; when the torch trigger

is released, the current starts to drop, taking the “slope-

down” time indicated by the LED L30, before reaching the

third current LED L31 where it stays for the time regulated

and displayed by the LED L33.

In this position the pedal control accessory ART. 193 can

be connected.

NOTE: in order for art. 193 to work well set:

1. rst current value (LED L23) at the desired one as pedal

minimum value

2. rst current time at zero (LED L24).

3. slope-up and slope-down time at zero (LED L25 and

L30)

4. third current at the minimum.

LED L5 - 5-stage TIG welding (automatic).

This program differs from the previous one in that the arc

is both started and shut off by pressing and releasing the

torch trigger.

LED L6 - TIG welding with three levels of

current.

To set the three minimum welding currents, proceed as

follows:

Press key T8 until the LED L28 lights, then adjust the

main current value using knob M1.

Press key T7 until the LED L23 lights, then adjust the

initial current value using knob M1.

Press key T8 until the LED L31 lights, then adjust the nal

current value using knob M1.

hen the arc strikes, the current reaches the rst setting

(LED L23lit); By keeping the key pressed, the operator

can maintain this current as long as desired (for example

until the part is heated). Upon releasing the torch trigger,

the current passes from rst

to second

level during the

slope time (LED L25); once the 2

level of welding current

is reached the LED L28 lights.

In order to pass to the 3rd current level the torch trigger is

to be pressed and kept pressed, while the current reaches

the 3rd value selected, in the slope time (LED L30): The

LED L31 will light, and the LED L28 will go off.

To switch off, press the torch trigger.

LED L7 - TIG welding with 4-stage current

levels.

To set the welding currents, proceed as follows:

Press key T8 until the LED L28 lights, then adjust the main

current value.

Press key T7 until the LED L23 lights, then adjust its

value; later on it is possible to adjust also this current time

LED L24.

Press key T8 until LED L29 lights, then adjust its value.

Press key T8 until LED L31 lights, then adjust its value.

Later on it is possible to adjust also this current time LED

L33.

By pressing and releasing the torch trigger, the current

moves to rst level (LED L23) and stays there for the

time previously regulated and displayed by the LED L24

before reaching the welding current in the “slope-up”

time indicated by the LED L25 the reaching of the welding

current is indicated by the start-up of the LED L28.

Should it be necessary to reduce the current during

welding, without shutting off the arc (for instance when

changing the welding material or working position, moving

from horizontal to upright, etc.), press and immediately

release the torch trigger, the current reaches the second

set value, the LED L29 lights and the LED L28 shuts off.

When the torch trigger is released, the current starts to

drop and takes the “slope-down” time indicated by the

LED L30, before reaching the third current LED L31

where it stays for the time regulated and displayed by the

LED L33.

In order to go back to the previous main current, repeat

the same torch trigger pressing and releasing action, the

LED L28 lights while LED L29 shuts off.

To stop welding at any time, simply hold down the torch

trigger for more than 0.7 seconds, then release it; the

current starts to gradually decrease in the time previosly

set (LED L20 lit) until reaching the crater current (LED

L31).

T3 Mode key.

With a long pressure (more than 0.7 sec) of this

key LEDS L8 or L9 are alternatively chosen.

With a short pressure (less than 0.7 sec) of this

key LEDS L10 or L11 are alternatively chosen.

2 LEDs will be always selected: one between LED L8 and

L9 and one between LED L10 and L11.

LED L8 - TIG welding with contact starting

(striking).

LED L9 - TIG welding starting with high

voltage/frequency device.

LED L10 - CONTINUOUS TIG welding.

LED L11 - PULSE TIG welding.

The pulse frequency is adjustable from 0.1 to

2,500 Hz (LED L27), peak current and base current can

be activated via LEDS L28 and L29, respectively, and are

adjustable using the knob M1.

With pulse frequency from 0.1 to 1.1 Hz display D1

alternatively shows peak current (main) and base current;

3.4. WELDING WITH COVERED ELECTRODES (MMA).

- This welding machine is suitable for welding all types of

electrodes which can be welded in direct current, with

the exception of cellulosic (AWS 6010).

- Check that switch BE is in O position, then connect the

welding cables in compliance with the polarity requested

by the manufacturer of the electrodes you are going to

use; connect the earth cable terminal to the workpiece

as close as possible to the welding point and make sure

that there is a good electric contact.

- Do not touch the torch or electrode clamp simultaneously

and the mass terminal at the same time.

- Turn the machine on using the switch BE.

- Select MMA process, by pressing key T1 until LED L2

lights.

- Adjust the current according to electrode diameter,

welding position and type of joint to be made.

- Always remember to shut off the machine and remove

the electrode from the clamp after welding.

If you wish to adjust the Hot-start and Arc force

functions, see second functions (paragraph 3.3.1).

3.5. TIG WELDING.

By selecting TIG (LED L1) with contact start-up or HF

(LED L8 or L9), you can weld:

- in TIG AC welding, aluminium, brass, and magnesium

- in TIG DC welding, stainless steel, iron, and copper.

Connect the mass cable connector to the positive pole (+)

of the welding machine, and the terminal to the workpiece

as close as possible to the welding point, making sure

there is good electrical contact.

Connect the power connector of the TIG torch to the

negative pole (-) of the welding machine.

Connect the torch controlling connector to connector BC

of the welding machine.

Connect the tting of the torch gas hose to the BD

machine connector and the gas hose coming from the

clinder pressure regulator to the gas tting BH.

3.5.1 Cooling unit (optiona for Art. 369).

If you use a water cooled welding torch, use the cooling

unit.

Insert the torch cooling hoses in the ttings BI and BL

of the cooling unit, being careful to correctly place the

delivery and return.

3.5.1.1 Description of protection devices.

- Coolant pressure protection device.

This protection is achieved by means of a pressure

switch, inserted in the uid deliver circuit, which controls

a microswitch. Low pressure is indicated b the ashing

message H2O on the display D1.

3.5.1.2 Start-up

Unscrew the cap BF and ll the tank (the equipment is

supplied with approximatel one liter of uid).

It is important to periodically check, through the slot BM,

that the uid remains at the “max” level”.

Insert the pressure switch connector and the power cord

into the sockets BR and BQ.

Turn on the machine.

To select the operating mode of the cooling unit, proceed

as follows:

1. Select the TIG Process.

2. Press at the same time keys T7 and T8 and hold both

down until the display D1 shows the abbreviation H2O.

3. Select the operation by means of knob M1.

OnC = continuous operation

OnA = automatic operation

To exit this selection brie press es T7 and T8.

If on start-up the uid does not circulate, it is necessar to

remove air from the tubes. In this case shut off the power

source, connect one end of the torch hose to tting BL

and insert the other end into the tank.

Turn the power source on for approximately 10 to 15

seconds while checking that water exits the tube. Shut

off the welding machine, connect the tube to the tting BI.

NOTE: “Automatic operation” means that the cooling unit

starts when the torch trigger is pressed and stops running

approximately 2 minutes after the torch trigger is released.

Warning! If MMA electrode welding is selected, cooling

is not on and may not be selected. It is normal for the

machine display D1 to show the ashing message 2O

on start-up.

3.5.2 Start-up

Do not touch live electrical parts and output terminals

when the machine is powered.

At rst start-up, select the operation mode b means of

key T3 and the welding parameters by means of key T8

and knob M1 as indicated in paragraph 3.3.

The inert gas ow must be set at a value (liters per minute)

approximately 6 times the electrode diameter.

If gas-lens type accessories are used, the gas delivery

can be reduced by approximately 3 times the electrode

diameter.

The ceramic nozzle diameter must be between 4 and 6

times the electrode diameter.

When ou have nished welding, do not forget to shut

off the machine and close the gas cylinder valve.

3.5.3 Preparing the electrode

Be especially careful when preparing the electrode tip.

Grind it so that it has a vertical groove as shown in the

gure 4.

FIG. 4

WARNING: LOOSE HOT METAL PARTS may cause

personal injuries, res and damages to the equipment;

TUNGSTEN CONTAMINATION may lower the quality of

the weld.

• Use only a grinder equipped with adequate safety guards

to shape the tungsten electrode and wear protections for

face, hands and body.

• To shape the tungsten electrodes, use a hard, ne-

grained abrasive grinding wheel used solely for this

purpose.

• Grind the tungsten electrode tip in a conical form and a

length 1.5 to 2 times the electrode diameter (g. 3).

3.5.4 “Synergy” welding.

The purpose of “Synergy” is to give the operator a

quick guidance to TIG welding parameters setting. It is

therefore not compulsory, but only a suggestion.

“Synergic” relationships between current thickness and

electrode diameter have been developed using Ceriati

grey 2% electrodes (EN 26848 WC20), at an alternating

current frequency of 90 Hz.

The teasts were carried out with the waveform n°. 12

(square penetration - sinusoidal cleaning).

The logic:

The operator sets the type of material to be welded, the

welding position and thickness in relation to the welding

process; an electrode diameter is suggested based on

these choices, and if conrmed the machine prepares for

welding.

Turn Synergy on.

Brie (less than 1.5 s) press ke T4: LED L12 (Syn) lights

simultaneously with LED L13 (material). Display D1 shuts

off and Display D2 shows an abbreviation corresponding

to the material to be welded (see description LED L13).

Turn the knob M1 to choose.

Pressing the key T4 again conrms the choice of material

and causes the LED L14 to light; the display D2 then

shows the welding positions available (see description of

LED l14).

Turn the knob M1 to choose. Pressing key T4 again

conrms the position selected and causes LED L15

to light; the display D1 shows the set current, while

the display D2 shows the thickness in millimeters that

corresponds to the current (see description of LED 15).

A further pressing of key T4 conrms the choice of

thickness and causes LED L16 to light.

One or more electrode diameters are proposed based on

the set choice of material, position, thickness and current.

The recommended electrode will be proposed rst and

the numerical value of the diameter will always be steadily

lit, next to the letter A; if the amp setting selected for

welding falls within the current range of two diameters,

the second choice of electrode diameter will be proposed

only by turning knob M1. The second choice will also be

displayed steadily lit. If you turn the knob further, on the

display D2 the diameter above the second choice and

the diameter below the rst choice will be ashing.

iven that the electrode diameter mainl denes the start

current level (LED L34) and the minimum current (LED

L23), the operator may choose a combination that is not

recommended.

At this point the operator has two choices:

1. To exit snerg without conrming the choices made.

To do this, brie press ke T4, the LED L12 shuts off

and the panel displays the settings in effect before you

entered synergy.

2. Conrm snerg b pressing ke T4 for more than 1.5

seconds. At this point all synergy functions are set and,

if selected using the key T8, the display D2 shows the

message “AU” (automatic).

The LED L12 remains lit to conrm that the parameters

have been set.

hen the electrode is conrmed, the LED L16 shuts off

and the LED L12 lights.

To summarize, when ou conrm the electrode diameter

(by holding down the button T4 when the LED L16 is

selected) the start (LED L37), wave (LED L38), Hz (LED

L39), balance (LED L40) and current (LED L23) functions

are arranged according to the automatic logic described

previously.

hen the electrode is conrmed, the LED L16 shuts off

and the LED L12 lights.

3.6. SAVING (JOB)

With this function the user can save in the machine the

settings

chosen and call them up later on. The machine features 9

memory positions for user settings, called JOBs.

When the operator is working and using one of these 9

settings saved LED L18 (JOB) is on and display D1 brie

shows the wording P01... P09.

3.6.1 Saving of parameters.

While in main display page (LED L18 off) the operator can

change any welding parameter.

B brie (one or more times) pressing ke T5 the user can

select the memory position chosen in a range from P01 to

P09. Display D1 ashes, D2 shows: --- and all LEDs are

off to indicate that that memory position is empty. With

a longer pressing of key T5 (for over 1.5 s) the machine

saves the settings in the selected position, the display

stops ashing and the LEDs light to indicates the setting

saved.

From position P09 b brie pressing ke T5 the user

exits JOB mode (LED L18 off).

3.6.2 Creating a JOB.

Brie press ke T5 until nding a position P..... empt

(display D1 ashing and displa D2 showing ---). Going

from left to right use keys T7 and T8 and knob M1 all

welding parameters desired.

A long pressure of key T5 saves those parameters.

3.6.3 Deleting a JOB.

Brie press ke T5 until reaching the desired position P...

(display D1 is not ashing), turn knob M1 until the display

D2 shows the wording DEL and press key T5 for over 1.5 s.

Display D1 starts ashing to indicate the OB has been

deleted.

3.6.4 Modifying a JOB.

Brie press ke T5 until reaching the desired position

(display D1 is not ashing) and use kes T7 and T8 and

knob M1 to modif the parameters selected. hen rst

modifying a parameter LED L18 starts ashing to indicate

that present position setting has been modied.

At this point it is possible:

• to overwrite present position: press key T5 till LED L18

stops ashing.

• to save in another position: brie press ke T5 until

reaching the new position desired and press key T5 for

a long time for the new saving.

• to cancel modications: press ke T5 ten times until

returning to the preceding position. LED L18 is not

ashing.
