Important: The water cooler is activated
from the menu "Basic Setup". Refer to "Ba-
sic Setup" section.
Ensure the gas and electrical supplies
are disconnected. Before proceeding,
remove the nozzle and the contact tip
from the torch.
• Open the side panel.
• Loosen the nut of the spool holder (brake
drum). In the case you are replacing the wire
spool, extract it.
• Remove the plastic protection from the spool.
Place it on the spool holder. Tighten the lock
nut turning it.
The unit can also accept 100 mm dia-
meter wire spools. For the mounting
follow these instructions:
• Remove the wire spool from the spool holder.
• Loosen the nut, mount the new spool and the
washers as shown in the picture 12.

Tighten nut (A) to appropriate tightness.
Excessive pressure strains the wire fee-
ding motor. Too little pressure does not
allow the proper wire feeding.
