PREPARING

FOR

MIG

WELDING WITH GAS

1)  Respect  the  indications  given  previously
concerning primary connection and installation.
2)  Connect  the  earth  cable  to  the  socket  of  the

WARNING

WELDING WIRE AND DRIVE PARTS FOR THE
FIRST

SECONDS ARE AT

WELDING

VOLTAGE.
KEEP HANDS AWAY.

Insert the wire in the wire feeder, making it adhere
to the race of the roller (ATTENTION: the roller has
two races because by turning it over it can be used
for another size of wire.Read the paragraph Rolls
Specifications ).
When  changing  the  section  of  the  wire  it  is
necessary  to  change  the  rollers  and  the  current
supply  pipe  (that  is  the  end  part  of  the  torch  from
which you can see the wire protruding).
Unscrew the outside end of the torch (nozzle) and
the current supply pipe to facilitate the passage of
the wire.
Unwind the torch cable so that the wire makes the
least possible number of curves .
Insert the plug in a suitable power socket.
Close  the  pressing  roller,  switch  on  the  machine

turning  the  line  switch  to  “ON”  position,  press  the
wire advance button to make the feeding motor run
until the wire comes out of the torch (keep the side
door  closed  while  performing  this  operation).
Switch  off  the  machine,  turning  the  line  switch  to
“OFF” position.
Screw the current supply pipe and the nozzle back
on.
Regulate  the  friction  of  the  wire  feeder  (a  more
accurate  regulation  will  be  possible  after  a  few
tests).

7)Press the Select Mode button (ref.6) to select the
desider  mode,  indicated  by  the  lighting  of  the

the ARC ON time and also the ARC OFF time.
Pressing

and

holding

the

torch

button

automatically is managed the ARC ON time and
ARC OFF time. If Toff is 0 seconds, the machine
will weld only a single spot then stops. (

Now, if you want to proceed with manual
welding act as described hereinafter, otherwise
see the section “PREPARATION FOR MIG
WELDING IN SYNERGIC MODE”

8) Regulate the wire speed using the encoder

A/W.Sp.

(ref.12).

9) Regulate the voltage using the encoder

V/SET

(ref.11).
