5.0.1 - TORCH CONNECTION

Plug the torch hose into the socket on the front of the welder having care
to not damage the contacts and secure by hand screwing in the threaded
connection.

5.0.2 - WIRE LOADING

ENSURE THE GAS AND
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). In
■
the case you are replacing the wire spool, extract it by pushing the
snap tongue (D) (Fig 16). Remove the plastic protection from the
spool. Place it on the spool holder. Tighten the lock nut (A) turning it
to position 2. (Fig. 16).
The unit can also accept 100
mm diameter wire spools.
For the mounting follow these
instructions:
Remove the wire spool (B)
■
from the spool holder (C).
Loosen the nut (A), remove
■
the spring and the washer;
remove the spool holder
(C) from the pivot.
Insert on the pivot the
■
100mm diameter wire
spool; Mount the washer
and the spring.
Tighten the lock nut (A).
■
Tighten nut (A) to appropriate tightness. Excessive pressure strains
the wire feeding motor.
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 (Fig.17). Open
the pressure arm of the
feeder. Extract the wire
from the torch liner.
When the wire is
■
disconnected, grasp
with pliers so that it cannot
exit from the spool. If
necessary, straighten it
before inserting it in the
wire input guide.
Insert the wire on the lower roll and in the torch liner.
■
WARNING: KEEP THE TORCH STRAIGHT. WHEN FEEDING 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 FOLLOW
THESE INSTRUCTIONS COULD CAUSE DAMAGE TO THE LINER.

MIG/MAG WELDING SETUP
Lower the pressure arm and place the pressure knob.
■
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
ARE
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.
NOTE: AFTER THREE SECONDS TORCH TRIGGER IS PRESSED
WIRE FEEDING SPEED INCREASES TO ALLOW A FAST EXIT OF
THE WIRE ON THE TORCH NECK.
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.
