ELECTRODE WELDING
• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode holder and earth
clamp. Connect the electrode holder and earth clamp as indicated on the electrode packaging.
• Respect the basic rules of welding.
• This device has 1 feature specific to Inverter machines :
- Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start, requires approximately
a 3 seconds delay before resuming normal welding operations.
SETTINGS PANEL (FIG V)
• Green light «ON»: when the machine is switched on the light turns on.
1
• In case of power failure, the green light goes off but the device remains powered while the
power cable is unplugged.
Orange light :
• Over-temperature: in such a case you shall wait a few minutes, the light will turn off and the
2
machine will start again.
• Over-current on primary circuit: in such a case you shall switch off the machine (with the main
switch) and switch on.
• Left button:
- MIG / MAG Welding : Adjust the wire feeder speed up to maximum speed.
3
- MMA welding : Adjust the welding current.
• Right button:
4
- Adjust the voltage reference up to the maximum value.
Advices
The wire speed adjustment is often determined « by the noise »: the arc must be stable and have a low crackling.
If the speed is too low, the arc is not continuous.
If the speed is too high, the arc crackles and the wire pushes back the torch.
PROCESS OF REELS AND TORCHES ASSEMBLY (FIG IV)
• Remove the contact tube and its support (fig D), and the nozzle (fig E) from the torch.
Fig A :
• Position the wire reel on the reel support :
• Adjust the reel brake (1) to avoid reel movement tangling the wire when welding stops. Be careful not to tighten too much.
Fig B :
The drive rollers included have 2 grooves (0,8 and 0,9). 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.
Nb : 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.
