5.0 LOADING WIRE

Your Mig welder is designed to accept either 5kg or 15kg wire spools of mild
steel, stainless steel or aluminium according to the type of metal you wish to
weld. Wire spools aren't supplied with the unit and must be purchased separately.
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 (A) of the spool holder (position 1) (brake
drum).Remove the spacer (E). In the case you are replacing the wire spool, extract
it by pushing the snap tongue (D) (Fig.3).
√ √ √ √ √
Remove the plastic protection from the spool. Place it on the spool holder. Mount the
spacer again (only for 5kg spools) and tighten the lock nut (A).

Tighten nut to appropriate tightness. Excessive pressure strains
the wire feeding motor. Too little pressure does not allow the im-
mediate stop of the wire spool at the end of the welding.
