6.0 MIG/MAG WELDING
6.1.1 TORCH CONNECTION
•
Plug the torch hose into the socket (9) on the front of the welder having care to not damage the
contacts and secure by hand screwing in the threaded connection.
6.1.2 WIRE LOADING
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 (I) of the spool holder (brakedrum) and
remove the spring (R) and the external ring (3). (Fig.4)
•
Remove the plastic protection from the spool (4) and
place it on the spool holder.
•
Mount the external ring (3), the spring (2) and the plas-
tic lock nut (1) again. These parts form the braking system
of the wire spool speed. NOTE: Do not tighten the nut too
much, excessive pressure strains the wire feeding motor, whi-
le too little pressure does not allow the immediate stop of the
wire spool at the end of the welding.
•
Loosen and lower the plastic knob (A) (Fig.5). Open the
pressure arm (B) of the feeder. Extract the wire from the torch
liner.
•
When the wire is disconnected, grasp it with pliers so
that it cannot exit from the spool. If necessary, straighten it
before inserting it in the wire input guide (C). Insert the wire
on the lower roll (D) and in the torch liner.
WARNING: keep the torch straight. When fee-
ding a new wire through the liner, make sure the
wire is cut cleanly (no burrs or angles) and that at least
2 cm from the end is straight (no curves). Failure to fol-
low these instructions could cause damage to the liner.
• Lower the pressure arm (B) and place the knob (A).
Tighten slightly. If tightened too much, the wire gets locked
and could cause motor damage. If not tighten enough, the
rolls will not feed the wire.
WARNING: When changing the wire diameter being used, or replacing the wire feed
roll, be sure that the correct groove for the wire diameter selected is inside, closest
to the machine. The wire is driven by the inside groove. Feed rolls are marked on the
side identifying the groove nearest that side.
•
Close the side panel of the machine.
•
Connect the power supply cable to the power output line. Turn on the switch. Press the torch
switch. The wire fed by the wire feeding motor at variable speed must slide through the liner. When
it exits from the torch neck, release the torch switch.
•
Turn off the machine.
•
Mount the contact tip and the nozzle.
When checking the correct exit of the wire from the torch do not bring your face
near the torch, you may run the risk to be wounded by the outgoing wire. Do not
bring your fingers close to the feeding mechanism when working! The rolls, when
moving, may crush the fingers. Periodically, check the rolls. Replace them when
they are worn and compromise the regular feeding of the wire.
