to avoid the reel inertia tangling the wire when welding stops. In general, do not tighten
too much!
• The electrical roller

is a double groove roller (0,8/1). The indication on the visible side of the roller is the
diameter in use. For a 0,8 wire, use the 0,8 groove.
• To set the adjusting knob of the pressing rollers, proceed as on picture

to the maximum
Start by pressing the torch trigger,
Tighten the adjusting knob while pressing the trigger.
When the wire starts to be restricted, stop the tightening.
AlSi5 : Recommendation for automotive aluminium for metal sheets > 1,5mm of thickness. NB: for the
aluminium wire put a minimum pressure in order not to crush the wire.
• Choose the contact tip diameter at the end of the torch. Use a contact tip adapted to the wire diameter used.
GAS COUPLING
Screw the regulator/flowmeter on the gas bottle

To avoid gas leaks, use the collars provided in the accessories box.
CHOICE OF REELS:
Possible settings:
* Consider Teflon sheath (ref 041548) and special aluminium contact tip (Ø 0, 8: 041059)

Welding mode choice
NORMAL (2T)
:
standard two-stage welding
DELAY: intermittent welding modes for an
optimised operating procedure.
SPOT : Spot welding with adjustable spot
diameter
Wire speed settings
Wire speed fitting potentiometer.
The speed varies from 1 to 15 m/minute.
SPOT/DELAY potentiometer fitting
Manual Mode
In manual mode, the wire speed is determinated by
the user by adjusting the potentiometer
.
Synergic Mode
Position the potentiometer in the middle of
the« OPTIMAL SYNERGIC » zone
In this mode, the device determines the optimal wire
speed according to 3 parameters:
Voltage
Wire diameter
The power mode
It is possbile to adjust the wire speed + / -.
