REEL AND TORCH ASSEMBLY (FIG. IV)
This product takes Ø 200/300 mm wire reel (ecological).
• Remove the contact tube and its support (fig. D), and the nozzle (fig. E) from the torch.
Fig A :
• Open the door of the machine.
• Place the reel on the drive pin (3) of the reel support.
• Adjust the reel brake (4) to avoid reel movement tangling the wire when the welding stops. Be careful not to tighten
too much - the reel must rotate without straining the motor.
Fig B :
• The drive rollers included have 2 grooves (0.8 and 1.0). For 0.8mm steel wire, use the V shaped groove.
• For flux cored wire, remove and reverse the roller to use the 0.9mm groove.
• For 0.8mm aluminium wire, remove and replace the roll with a model specifically designed for aluminium with a U shaped groove
(not included).
Fig C :
To select the adjustment of the drive rollers.
• Loosen the drive roller knob (3) as far as possible and insert the wire, tighten the knob again slightly.
• Start the motor by pressing the trigger of the torch.
• Tighten the knob whilst pressing the trigger until the wire starts to move.
ATTENTION: When welding with Aluminium, use the minimum possible pressure to avoid crushing the wire.
• Leave about 5cm of wire out of the torch, then put the contact tube (fig. D), and the nozzle (fig. E) adapted to the wire to be
used at the extremity.
GAS CONNECTION
- Connect the manometer (flowmeter) to the gas bottle if needed, then connect the gas hose to the gas connector. To avoid gas
leak, use collars supplied in the accessories box.
- Set the gas flow by adjusting the dial located on the pressure regulator.
NB : to help facilitate the adjustment of the gas flow, operate the drive rollers by pressing the trigger of the torch (ensure that the
drive roller is completely loose so the wire is not fed through). Maximum gas pressure 0.5 MPa (5 bars). This procedure does not
apply to «Gasless» welding mode.
RISK OF INJURY DUE TO MOVING PARTS
The wire feeders contain moving parts that may catch hand, hair, clothes or tools which can lead to injuries! Take
extra care.
• Do not lay a hand to swivel or moving components or parts to the drive!
• Ensure that the housing covers or protective covers remain closed during operation!
• Do not wear gloves when feeding the wire through or changing reel.

CONNECTIONS AND RECOMMENDATIONS
• Connect the cables, electrode holder and earth clamp in the connectors,
• Respect the welding polarities and intensities indicated on the electrodes boxes,
• Remove the electrode from the electrode holder when the machine is not in use.
MODE SELECTION AND SETTING
Press the left button to select MMA welding.
Setting the welding current :
Adjust the welding current using the central knob
work to be carried out. The current setpoint is indicated on the central side
display.
WELDING CURRENT SETTINGS
The following settings concern the current range that may be used depending on the electrode's type and diameter. These ranges are
quite large as they depend on the application and the welding position.
