MIG/MAG / Puls MIG / DOUBLE Puls
MIG welding with SHIELD GAS
To begin MIG/MAG / Puls MIG / DOUBLE Puls MIG welding,
carry out the following tasks (with the welding power source
switched off).
1 - Connecting the cables (Fig. C1)
1) Connect the gas hose to the pressure reducer fitted on
the cylinder beforehand. Gas cylinders are supplied with
a pressure reducer to adjust pressure of the gas used for
welding.
2) Screw the torch to the centralised connection on the front
panel of the welding power source (Pos. 3, Fig. A).
3) Connect up the earthing system cable to the rapid cou-
pling marked by a - (negative) symbol and then the rel-
evant ground clamps to the piece being welded or to its
support in an area free from rust, paint and grease. Using
particularly long earthing cables reduces the voltage and
causes some problems from increased resistance and in-
ductance of the cables that could cause faulty welding. Fol-
low instructions to avoid these problems:
•
Use earthing and extension cables with appropriate sec-
tion.
•
Lay out the cables as a flat as possible to prevent them
from coiling up.
4) Connect the reverse polarity cable to the positive terminal
(Fig. C2).
2 - Welding
1) Switch the welding power source on by moving the power
supply switch to I (Pos. 6, Fig. B).
2) Make the adjustments and do the parameter settings on the
control panel (for further information see the control panel
manual).
3) Load the wire using the torch button, after having removed
the wire guide nozzle from the torch to allow the wire to
come out freely, while loading (remember that the wire
guide nozzle must correspond to the diameter of the wire
used).
4) Open the tap on the cylinder slowly and adjust the reducer
knob to obtain a pressure of about 1,3 to 1,7 bar, and reg-
ulate the flow to a value between 14 and 20 lit/min to suit
the current used for welding.
5) The welding power source is ready to weld. Start welding
by moving close to the welding point and press the torch
button.
6) Once welding has been completed remove any slag, switch
off the welding power source (which is only to be done
when the fan is not running), and close the gas cylinder.
