1,a,b) Selecting the torch type**
Three torch types can be selected:
Normal torch: with the welding start trigger.
Torch with wire speed adjustment on the gun: facilitates welding control.
Torch Spool gun: (with a continuous wire spool housed in the handle) ideal for use
with soft wire (aluminium) with no drawing problems.
L For installation, follow the instructions in Fig. 9.
2) Adjusting the welding current
Select the welding current according to the work to be carried out. Start with a low current
if the metal is thin. Then increase the current until the best position is found.
L Do not adjust the welding current while welding, as the current could damage the
switches.
3) Synergic / Manual welding mode selection
Upon starting the machine, the Synergic MIG control is set in synergic mode, in the last
program used.
The message “Synergic” and the program set are displayed on the display.
The Synergic MIG control stores the last program set for each torch. For model 3, it
stores only the programs of the regular torch 1 and 2.
Synergic program setting
¾ Select in the following order: wire type: “WIRE”, its diameter: “WIRE DIAM”, gas type:
“GAS”. The values ash when there are more options available for wire type. Press
the corresponding switches to conrm or modify the selection. Once the selection is
completed, all the indicators will be xed on. If you attempt to weld, without completing
the selections, the welder would not start and the message “SET” is shown on the display.
¾ Place the potentiometer on the neutral value “0” of the “SYN” scale. Then, adjust the
value proposed by the Synergic MIG control up to +/- 20%.
Manual welding mode
¾ Press the “Man /Syn” switch. The message “Manual” is displayed on the screen. The
welding machine operates in regular mode.
¾ Adjust the wire speed with the potentiometer Fig.4,4.
L In welding machines with several types of torches (Spool On Gun, etc.) synergy or wire
speed are adjusted only with the potentiometer placed on the torches.
4) 2 stroke 4 stroke selector
In the 4 stroke position the torch button changes function. When the button is pressed,
the gas is delivered, and when released welding starts. By pressing the button once more
the welding stops, and once more again also the gas delivery stops.
The selection is shown on the display.
5) Selector for Continuous welding: “Cont”; Spot welding:
“Spot”; “Stitch” (sequence of welding cycles and pause)
¾ Press the switch several times to select the welding mode.
The selection is shown on the display.
¾ Adjust the welding time in the “Spot” and “Stitch” modes with the “+ , -“ switches .
¾ The selection is shown on the display.
L In the “Stitch” mode you can also adjust the pause time present in the secondary
parameters.
6) Secondary parameters selector
¾ Press the “Menu” switch several times to select the parameter and change its value
with the “+ , -” switches. Modications become active 5 seconds after the last switch
release, when the control automatically exits the secondary parameters list.
The selection is shown on the display.
Burn back: Modies the length of the wire that remains outside the contact tip at
the end of the welding operation. The setting carried out at the factory should be
correct.
Soft start: Modies the approach speed of the wire to the piece to be welded at the
start of welding. The setting carried out at the factory should be correct.
Pause time: Pause time in “Stitch” mode
Back light: Display brightness
Contrast: Screen and message contrast
L Welding not allowed while “Menu” is open.
L Adjustments are not allowed when torch switch is pressed. Only the potentiometer on
the control or on the torch is active.
7) Ammeter Voltmeter
The welding voltage and current values are shown on the display during welding and for
10 seconds after welding ends.
8) Thermal cut-out signal
The message “Thermal protection” on the display signals that the thermal cut-out
protection is on.
If the duty cycle “X” shown on the data plate is exceeded, a thermal cutout stops the
machine before any damage is caused. Wait for operation to be resumed and, if possible,
wait a few minutes more.
If the thermal cutout continues to cut in, the welding machine is being pushed beyond its
normal performance levels.
Wire loading function
In “2T” “CONT” mode, press the torch switch for more than 3 seconds: the gas ow is
interrupted, the torch is not energised and the wire moves at reduced speed.
In “4T”, “CONT” mode, the function is similar, 3 seconds after the torch switch is
released.
When the loading function is active, the message “Wire Load” is shown on the display.
** (This component may not be included on some models).
Recommendations for use
Only use an extension lead when absolutely necessary and providing it has an equal or
larger section to the power cable and is tted with a grounding conductor.
Do not block the welder air intakes. Do not store the welder in containers or on shelving
that does not guarantee suitable ventilation.
Do not use the welder in any environment in the presence of gas, vapours, conductive
powders (e.g. iron shavings), brackish air, caustic fumes or other agents that could
damage the metal parts and electrical insulation.
L The electric parts of the welder have been treated with protective resins. When used for
the rst time, smoke may be noticed; this is caused by the resin drying out completely.
The smoke should only last for a few minutes.
Maintenance
Switch off the welder and remove the plug from the power socket before carrying out any
maintenance operations.
Ordinary maintenance to be carried out periodically by the operator depending on use.
• Check the gas hose, torch cable and ground cable connections. • Clean the contact
tip and the gas diffuser with an iron brush. Replace if worn. • Clean the outside of the
welder with a damp cloth.
Every time the wire spool is replaced:
• Check the alignment, cleanliness and state of wear of the wire roll Fig.12. • Remove
any metal powder deposited on the wire feeder mechanism. • Clean the wire guide liner
with anhydrous solvent and grease remover and dry with compressed air. • Check the
condition of the warning labels. • Replace any worn parts.
Extraordinary maintenance to be carried out by expert staff or qualied electrical
mechanics periodically depending on use. (Apply the rule EN 60974-4).
• Inspect the inside of the welder and remove any dust deposited on the electrical parts
(using compressed air) and the electronic cards (using a very soft brush and appropriate
cleaning products). • Check that the electrical connections are tight and that the insulation
on the wiring is not damaged.
