Open the motor panel.
Insert the reel onto the spindle so that the end of the wire is
facing upwards. Make sure that none of the loops of wire on
the reel are overlapping and that the wire unwinds smoothly.
Check that the towing roller is inserted into the groove which
has the same diameter as the wire to be used, if this is not
the case, rotate the roller. Take the end of the wire and cut it,

the pressure between the towing rollers is not too strong, nor
too weak. Excessive pressure may break the wire. Let the
wire unwind for the entire length of the torch. To prevent the
wire from implanting itself into the end of the torch, the
contact tip should be removed. It should be remembered
that the contact tip has to correspond

Replacing the torch
To replace the torch, for instance to repair it, proceed as
follows:
f) Loosen the screws of the casing of the towing motor.
2) Disconnect the gas connection.
3) Loosen the locking nut of the power supply cable.
