feed speed (and thus the corresponding current). The set
metres per minute will be added to or deducted from this
value, alternatively.
Prior to execution, it should be remembered that in a
correct seam the overlapping between one "weld pass"
and the other must be at least 50%.
Water unit (only for items 384 and 385).
•
Display A shows the words WATER UNIT. This function
allows the setting of the cooling unit start-up.
Pressing the knob B, the display A shows ON-OFF-AUTO
function.
If "AUTO" is selected, when the machine is switched on,
the cooling unit starts; if the torch trigger is not pressed,
after 30 seconds it shuts off.
By pressing the torch trigger, the group starts again and
shuts off 3 minutes after releasing the torch trigger.
To activate the desired function, select between ON OFF
and AUTO with knob C. After having confirmed the choice,
it is possible to return to the previous screen (PROCESS
PARAMETERS) by pressing knob B.
By default the OFF function is selected.
Factory OFF
•
The purpose is to return the welding machine to the
original default settings.
To access the function, simply highlight it using the knob B
and press it, the display screen A shows the words OFF
and ALL. To make the reset, highlight the word ALL and
press the knob B. After confirming the selection made, to
return to the previous page (PROCESS PARAMETERS)
press the knob B. If you want to go back to the main menu,
press the knob B again for at least 2 sec.
5.2 MIG WELDING WITHOUT GAS
The actions to prepare the welding machine for work are the
same as those described previously, but for this type of
welding proceed as follows:
Mount a coil of flux-cored wire for welding without gas.
The separate wire feeder must remain connected to the power
source.
Connect the earth cable to the positive pole O and the power
cable adaptor of the wire feeder/power source to the negative
pole G using the optional connection cable code 530347.
Connect the welding torch to the euro adapter D.
Select the program suited for flux-cored wire. The program is
available only in MIG SHORT SYNERGIC and MIG MANUAL
processes.
5.3 WELDING WITH COATED ELECTRODES (MMA).
Before welding it is recommended to remove the MIG torch
and mount the electrode holder.
The separate wire feeder must remain connected to the power
source.
Connect the electrode clamp cable connector to connector O
and the earth cable clamp to connector G (observing the
polarity stated by the electrode manufacturer.
VERY IMPORTANT: Connect the terminal of the earth cable
to the workpiece, making sure that contact is good to ensure
smooth equipment operation and avoid voltage dips with the
workpiece.
Turn on the welding machine.
To choose this process, just select it with the knob B and
press the latter.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- H. Start Time
- H. Start Curr.
- A. Force Curr.
- Factory
- Password
Keep the knob B pressed to go back to the previous page
(PROCESS PARAMETERS).
To go back to the main menu, press the knob B again for at
least 2 sec.
Do not touch the electrode clamp and the earth clamp
simultaneously.
Always remember to shut off the machine and remove the
electrode from the clamp after welding.
5.4 TIG WELDING
Before welding it is recommended to remove the MIG torch
and mount the TIG torch.
The separate wire feeder must remain connected to the power
source.
Connect the earth cable to the positive pole O and the power
cable adaptor of the wire feeder/power source to the negative
pole G using the optional connection cable code 530347.
Connect the welding torch to the euro adapter D.
Connect the gas hose to the outlet of the pressure regulator of
an ARGON cylinder.
Use a 2% thorium-covered tungsten electrode (red strip),
diameter 1.6 ( 1/16" ).
Turn on the machine using the switch I.
To choose this process, just select it with the knob B and
press the latter.
From the process, using the knob B, it is possible to select
and set (with the knob C) the following functions:
- Start Mode
- Slope Up
- Slope Down
- Pulse
- Spot
- Pre Gas
- Post Gas
- Factory
- Password
Keep the knob B pressed to go back to the previous page
(PROCESS PARAMETERS).
To go back to the main menu, press the knob B again for at
least 2 sec.
Strike the arc by contact using a firm, rapid stroke.
Always remember to shut off the machine and close the
gas cylinder valve when you have finished welding.

6 MAINTENANCE

Periodically make sure that the welding machine and all
connections are in good condition to ensure operator safety.
After making a repair, be careful to arrange the wiring in such
a way that the parts connected to the power supply are safely
insulated from the parts connected to the welding circuit.
Do not allow wires to come into contact with moving parts or
those that heat up during operation.
Mount the clamps as on the original machine to prevent, if a
conductor accidentally breaks or becomes disconnected, a
connection from occurring between power supply and the
welding circuits.
