Elettro MIG 245 DOUBLE TORCH Betriebsanleitung Seite 9

I – Central connection SIDE A
Where the welding torch is connected.
J – Commutator
Selects the machine side.
When the commutator is in position A, SIDE A of the machine is
activated.
•
Weld with the torch connected to the SIDE A central attachment
I.
•
Gas used for welding is fed from the cylinder connected to the
SIDE A gas fittings U.
When the commutator is in position B, SIDE B of the machine is
activated.
•
Weld with the torch connected to the SIDE B central attachment
P.
•
Gas used for welding is fed from the cylinder connected to the
SIDE B gas fittings S.
K – Display.
Using the manual program 00 the instrument displays the wire speed
in meters per minute before welding, and the current while welding.
Using the synergic programs it always displays the current.
As described in the paragraphs above, the following may be displayed
on the instrument before beginning to weld: the program being used,
the spot welding time, the pause time, the Burn-Back time, the
recommended thickness, the Soft Start function, the speed set on the
motor of the WEL3105, and the post-gas time.
The last program used and the settings relative to it, are saved and
displayed on display K when the method of welding from side A to
side B is commuted, and also when the machine is disconnected from
main supply.
L – M- Keys.
• When the LED A is lit, the display K shows the program number
selected by the 2 keys. Once the selection has been completed the
LED remains lit for 5 more seconds, then shuts off.
• When the LED B is lit the display K shows the time selected by the
2 keys. Once the selection has been completed the LED remains lit for
5 more seconds, then shuts off.
• When the LED C is lit, the display K shows the time selected by the
2 keys. Once the selection has been completed the LED remains lit for
5 more seconds, then shuts off.
• When the LED D is lit the display K shows the time selected by the
2 keys. Once the selection has been completed the LED remains lit for
5 more seconds, then shuts off.
• When the LEDs A, B, C and D are off and we are within any
synergic program, pressing one of the 2 keys will cause the display K
to show either the current set or the recommended thickness in
millimetres.
Adjusting the selector switch Q, you can see, on the display K, the
increase or decrease in the value selected. This function is used when
one wishes to know in advance at what current or thickness welding is
to begin.
• Pressing the 2 keys simultaneously for at least 5 seconds causes
us to enter the sub-menu, where we find 3 functions that may be
selected via the key E:
1 – Soft Start (speed).
Changes the wire speed from the one set; this speed remains active
for the time governed by the Soft Start function (time).
The speed may be adjusted using the 2 keys L – M from 10% to a
maximum of 150% of the set welding speed.
WEL2600
This function, combined with the Soft Start function (time), serves
to improve arc striking. The value shown on the display K is
preceded by the letter (A).
2 – Speed set on the motor of the WEL3105.
Adjusting the two keys L – M varies the speed of the WEL3105
from –9 to +9 compared to the set value. This function maximizes
wire advancement, putting the wire feeder motor of the welding
machine in step with the motor of the WEL3105. The value shown
on the display K is preceded by the letter (H).
3 – Post gas.
Using the two keys L – M, it is possible to adjust the gas flow after
welding to between 0 and 5 seconds. This function is especially
useful when welding stainless steel and aluminium. The value
shown on the display K is preceded by the letter (P).
4 – Soft Start (time).
Adjusts the time for which the Soft Start speed remains active. This
function, combined with the Soft Start function (speed), serves to
improve arc striking.
Using the 2 keys L – M, the Soft Start time may be adjusted from 0
to 1 second. The value shown on the display K is preceded by the
letter (D).
5 – Two-stage manual mode and 4-stage automatic mode.
Adjust the 2 keys L – M to select the 2-stage or 4-stage mode.
If the welding machine is set to 2-stage manual mode, welding
begins when the button E is pressed, and stops when it is released.
If the welding machine is set to 4-stage automatic mode, press the
torch trigger to begin welding; you may release the trigger once the
procedure has begun.
Press and release the trigger again to stop welding. This setting is
suitable for long-term welding, where the welder may tire of
holding down the torch trigger. The value shown on the display K
is preceded by the symbols (2t and 4t).
N – Setting knob.
Adjusts the wire speed, and is active only when using the standard
welding torch and not the WEL3105 torch.
When using the program 00, adjusts the welding wire speed from 0 to
20 meters/minute.
When using any synergic program, the knob indicator must be set to
the label SYNERGIC. Choose a synergic program; the display K
indicates the current set by the selected program. This current
corresponds to a given speed. If you wish to correct this speed, simply
turn the knob clockwise to increase or counter-clockwise to decrease.
Changes in wire speed are always indicated on the display K by a
current.
O – 10-pin connector.
This connector must be connected to the 10-pin patch connector of the
WEL3105 torch.
P – Central connection SIDE B
Where the welding torch is connected.
This connection can also be used for a WEL3105 type torch.
Q – Selector switch.
Adjust the welding tension.
