MIG/MAG / Puls MIG / DOUBLE Puls
MIG welding without 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. D1)
1) Screw the torch to the centralised connection on the front
panel of the welding power source (Pos. 3, Fig. A).
2) Connect up the earthing system cable to the rapid cou-
pling marked by a + (positive) symbol and then the relevant
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 inductance of the
cables that could cause faulty welding. Follow 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.
3) Connect the reverse polarity cable to the negative terminal
(Fig. D2).
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.
