- : Post-gas. Use to adapt the protective gas outow starting from when

welding is stopped.

: Welding current SLOPE DOWN. Used to gradually reduce the current on

releasing the torch button.

N.B.: The current welding parameters, wire feeding speed and material thickness are

related to each other based on a synergic curve.

The actual welding settings (wire speed, welding current and voltage) are shown in the

top section of the display.

7.2.1ATCMode(AdvancedThermalControl)

This is enabled automatically when the thickness selected is less or equal to 1.5 mm.

Description: the particular instantaneous control of the welding arc and the ultra rapid

correcting of parameters minimize current spikes, something that is characteristic of

Short Arc transfer procedures, to the advantage of a low thermal load on the piece

to be welded. The result, on the one hand, is reduced deformation of materials and,

on the other, a uid and accurate transfer of the weld material and the creation of a

welding seam that is easy to model.

Advantages:

- easy welding of thin materials;

- decreased deformation of material;

- stable arc even when working with low currents;

- rapid and accurate spot welding;

- easier coupling of spaced sheets.

7.2.2Usingthespoolgun

All the settings procedures (material, wire diameter, gas type) are described above.

The spool gun knob (Fig. I-5) adjusts the wire speed (and the welding current and

thickness simultaneously). The user only has to adjust the arc voltage via the display

(if necessary).

7.3ABPulseoperatingmode

Pulse mode settings (Fig. L-6).

Press and hold the knob C-5 for at least 3 seconds to access the material, thread

diameter and gas type settings menu. (Fig. L-4). The welding machine sets itself

automatically in the best operation conditions established by the different synergy

curves that are saved. The user only has to select the material thickness to begin

welding.

An additional two parameters are available compared to the synergic operating mode:

: Inrush current.

: Duration of inrush current. If the parameter is set to zero, this function is

disabled.

7.4ABPoP(PULSEonPULSE)operatingmode

Pulse mode settings (Fig. L-7).

PoP mode is used to perform pulse welding with 2 current levels (I

and I

) with a

duration of T2 and T1 respectively.

The following variables are available compared to the PULSE operating mode:

: Secondary welding current;

: Secondary arc correction according to preset arc voltage;

: Secondary wire feed speed;

: Secondary material thickness;

: Duration of I

current;

: Duration of I

current.

7.5ROOTMIGoperatingmode

ROOT MIG mode settings (Fig. L-8).

The settings available are the same as those for synergic mode (see 7.2).

8.CONTROLLINGTHETORCHPUSH-BUTTON

8.1Settingthetorchpush-buttoncontrolmode(Fig.L-9)

Press the knob (Fig. B-5) for at least 3 seconds to access the parameter settings

menu.

8.2Torchpush-buttoncontrolmode

It is possible to set 4 different torch push-button control modes:

2Tmode

Welding begins when the torch push-button is pressed and ends when the push-

button is released.

4Tmode

Welding begins when the torch push-button is pressed and released, and ends only

when the torch push-button is pressed and released a second time. This mode is

useful for long welding operations.

4TBi-Levelmode

Welding begins when the torch push-button is pressed and released. Each time it is

pressed/released it switches from current (I

symbol) to current (I

symbol) and vice-

versa. It only terminates when the torch push-button is pressed for a certain set time.

Spotweldingmode

Used for MIG/MAG spot welding with control of welding duration.

9.WELDINGWITHG.R.A.(for270Aversiononly).

The welding machine recognizes automatically the G.R.A. connection. On the display

there appears the symbol

. When the torch pushbutton is pressed, the G.R.A.

is activated. It is possible to disable the G.R.A. function, by following the instructions

reported in chap. 12. In this case on the display there appears the symbol

10.MMAWELDING:PROCESSDESCRIPTION

10.1GENERALPRINCIPLES

- It is essential to follow the recommendations provided by the manufacturer on the

electrode packaging which indicates the correct electrode polarity and relative rated

current.

- Welding current is regulated to suit the diameter of the electrode being used and the

type of soldering to be performed; an example of the currents used for the various

electrode diameters can be seen below:

Ø Electrode (mm)

Weldingcurrent(A)

Min. Max.

1.6 25 50

2.0 40 80

2.5 60 110

3.2 80 170

- One can see that for the same diameter electrode, high levels of current will be

used for at welding, whilst lower current levels will be used for vertical or overhead

welding.

- The mechanical characteristics of the welded joint are determined by the intensity

of the selected current and also other welding parameters such as the length of the

arc, the operating speed and position, the diameter and quality of the electrodes

(to ensure correct conservation, use special packaging or containers to store and

protect the electrodes against humidity).

 WARNING:

 Instability of the arc due to the composition of the electrode can occur,

dependingonthebrand,typeandthicknessoftheelectrodecoatings.

10.2PROCEDURE

- Keeping the mask IN FRONT OF YOUR FACE, rub the tip of the electrode on the

piece to be welded, moving as if striking a match; this is the most correct method for

igniting the arc.

 WARNING: DO NOT TAP the electrode against the workpiece, which could

damagethecoatingandmakearcstrikingdifcult.

- As soon as the arc has struck, try to keep the electrode at a distance from the

workpiece that is equivalent to the diameter of the electrode being used, and keep

this distance as constant as possible while welding; remember that the electrode

angle while moving forward must be approx. 20-30 degrees.

- At the end of the welding seam, take the electrode end slightly back as to the forward

direction, above the crater to ll it, then quickly lift the electrode from the weld pool

to switch off the arc (Aspects of the welding seam - FIG. M).

10.3MMAmodesettings(Fig.L-10)

The user can customise the following welding parameters (Fig. L-11):

: Welding current measured in Amperes.

: This is the initial “HOT START” overcurrent, the display shows the

percentage increase as to the value of the selected welding current. This adjustment

improves starting.

: This is the dynamic “ARC-FORCE” overcurrent, the display shows the

percentage increase as to the value of the pre-selected welding current. This

adjustment improves welding uidity, prevents the electrode from adhering to the

workpiece and makes it possible to use different types of electrodes.

: ON/OFF: this enables or disables the device that reduces the loadless

output voltage (ON or OFF setting). With the VRD enabled, operator safety increases

when the welding machine is on but not in the welding mode.

The actual welding settings (welding current, voltage and the diameter of the

suggested electrode) are shown in the left section of the display.

11.TIGDCWELDING:PROCESSDESCRIPTION

11.1GENERALPRINCIPLES

TIG DC welding is suitable for all types of low-alloy and high carbon steel, and heavy

metals such as copper, nickel, titanium and their alloys (FIG. N). An electrode with 2%

Cerium (grey band) is normally used for TIG DC welding with electrode at the (-) pole.

The tungsten electrode must be axially sharpened using a grinding wheel, see FIG. O;

make sure the tip is perfectly concentric to prevent arc deviation. The electrode must

be ground along its length. This operation must be repeated periodically according

to the use and wear state of the electrode, or when the electrode itself has been

accidentally contaminated, oxidised or used incorrectly. For the welding to be good,

the exact diameter of the electrode must be used with the exact current, see table

(TAB. 5). The electrode normally projects from the ceramic nozzle by 2-3 mm, but can

reach 8 mm for welding edges.

The weld is created by the edges that melt. Filler metal is not needed when welding

suitably prepared thin material (up to about 1 mm) (FIG. P).

A greater thickness requires rods made from the same material as the basic material

and with a suitable diameter, with edges that have been suitably prepared (FIG. Q).

For welding to be successful, the pieces must be carefully cleaned and free from

oxide, grease, oil, solvent, etc.

11.2PROCEDURE(LIFTSTRIKE)

- Use the knob B-5 to adjust the welding current to the required rate; adjust this value
