WEAR PROTECTIVE GLOVES WHEN THREADING THE WIRE.
- Remove the cover by unscrewing the relative screw (1).
- Position the wire coil onto the reel.
- Release the pressure counter-roller and distance it from the lower roller (2).
- Free the wire end, cut off the misshaped end by cutting it cleanly and without leaving
a burr; rotate the reel counter-clockwise and position the wire end into the wire feed
input, pushing it by 50-100 mm into the torch swan neck (2).
- Reposition the counter-roller, adjusting the pressure at an intermediate value, make
sure the wire is positioned correctly in the hollow of the lower roller (3).
- Gently stop the reel, using the relative adjustment screw.
- With the SPOOL GUN connected, insert the welding machine plug into the mains
socket, switch on the welding machine, press the spool gun push-button and wait
for the end of the wire which is running along the whole wire feed casing, to exit by
100-150 mm from the front of the torch, then release the torch push-button.
6. MIG-MAG WELDING PROCESS DESCRIPTION
6.1 SHORT ARC
The wire melts and the weld bead detaches because the wire tip in the weld pool short-
circuits (up to 200 times per second). The free length of the wire (stick-out) is normally
between 5 and 12 mm.

7. MIG-MAG OPERATION MODE
7.1 Operation in SYNERGIC mode
When the parameters such as material, wire diameter
defined by the user, 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 (OneTouch Technology).

welding selected previously.

7.1.2 Setting the parameters
To access the parameter adjustment menu press the knob (Fig. C-2) for at least 1
second then release it:
a) material selection (Fig. L-2 material flashing)
- rotate the knob (Fig. C-2) to select the required material and confirm by pressing
and releasing the same knob;
b) wire diameter selection (Fig. L-3 wire diameter flashing)
- rotate the knob (Fig. C-2) to select the required material and confirm by pressing
and releasing the same knob;
c) gas selection (Fig. L-4 gas type flashing)
- rotate the knob (Fig. C-2) or directly select the proposed gas and confirm by
pressing and releasing the knob; this allows exiting from the parameter settings
menu and the display on the monitor of the pre-set values.
After having defined with the knob (Fig. C-1) the material thickness (Fig. L-5) the user
can start welding.
7.1.3 Using the spool gun
All the settings procedures (material, wire diameter, gas type) are described above.
Use the knob (Fig. C-1) to define the width of the material (Fig. L-5). Set the wire
feeding speed using the knob on the spool gun (Fig. I-5). If it falls within a set interval
(recommended value) the torch symbol light will remain fixed, otherwise it will flash.
It is now possible to start welding.
7.1.4 Adjusting the welding seam shape
The shape of the welding seam can be adjusted using the knob (Fig. C-2) which
adjusts the arc length, therefore establishing the higher or lower temperature for
welding.
The adjustment scale ranges from -9 ÷ 0 ÷ +9; in most cases the optimal basic setting
is given (the value is shown on the LCD display to the left of the graphic signal showing
the welding seam and disappears after a set time) when the knob is in the intermediate
position (0 ).
Using the knob (Fig. C-2) the graphic indication on the display of the welding seam
changes, showing a more convex, flatter or more concave result.
Convex shape. It means that there is a low thermal supply therefore welding is
"cold", with little penetration; rotate the knob clockwise for greater thermal supply to

"hot", with excessive penetration; rotate the knob counter-clockwise for lower fusion.
7.1.5 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 fluid 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 Operation in MANUAL mode
The user can personalise all the welding parameters.

7.2.2 Setting of torch T1 and T2 parameters
In manual mode, the wire feeding speed and the welding voltage are adjusted
separately. The knob (Fig. C-1) adjusts the wire speed, the knob (Fig. C-2) adjusts
the welding voltage (which determines the welding power and influences the seam
shape). The welding current is shown on the display (Fig. M-2) only during welding.

In manual mode, the wire feeding speed and the welding voltage are adjusted
separately. The spool gun knob (Fig. I-5) adjusts the wire speed, the knob Fig. C-2
adjusts the welding voltage (which determines the welding power and influences the
seam shape). The welding current is shown on the display (Fig. M-2) only during
welding.
The knob (Fig. C-1) is not enabled.
7.3 T1, T2 and SPOOL GUN torch settings
The T1, T2, SPOOL GUN torch settings can be edited in two different ways:
- press the button on the control panel (Fig. C-4) where the corresponding LED will
come on;
- press and release, after at least one second, the button for the torch to be used until
the corresponding LED comes on.
8. CONTROLLING THE TORCH PUSH-BUTTON

8.1 Torch push-button control mode
3 different torch push-button control modes can be set, which remain valid with both
synergic and manual operation:
Spot welding mode (Fig. N-5)
Use for MIG/MAG spot welding with control of welding duration (when at OFF
excluded; 0.1÷5 seconds).
2T mode (Fig. N-6)
Welding begins when the torch push-button is pressed and ends when the push-
button is released.
4T mode (Fig. N-6)
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.
8.2 Setting the torch push-button control mode
To access the parameter adjustment menu press the knob (Fig. C-2) for at least 3
second then release it:
a) Spot welding time adjustment (Fig. N-5 flashing).
Rotate the knob (Fig. C-2) to select the required time or select "OFF" to disable the
function; confirm by pressing and releasing the same knob.
If the spot welding time is set at a value of between 0.1-5 sec., the "2T/4T" modes
cannot be selected. In this case pressing the knob causes the exit from the menu.
b) 2T or 4T selection (Fig. N-6 flashing and "2T" or "4T" written on Fig. N-7).
The user can select whether to use the 2T or the 4T mode, but only if the spot
welding time is set at "OFF". Rotate the knob and select the required mode, then
confirm and exit from the menu by pressing the knob.
9. ADVANCED SETTINGS
9.1 Adjustable advanced parameters
The following welding parameters can be personalised, both when working in synergic
and manual mode:
Wire up slope (Fig. N-1)
Use to set the wire starting slope to prevent initial accumulation in the welding seam.
Adjustment from 30 to 100 (start as a % of the running speed).
Electronic reactance (Fig. N-2)
Use to set the welding dynamics according to the material and gas used.
Adjustment from 0 (machine with little reactance) to 5 (machine with great reactance).
Wire burning when welding stops (burn back) (Fig. N-3)
Use to adjust the wire burn back time, optimising the final wire cut to make restarting
welding easier.
Adjustment from 0 to 200 (hundredths of a second).
