REPLACEMENT OF THE
WIRE SPOOL
Your welding power source is supplied with a mini
wire spool of about 0.5 Kg of 0.6mm diameter wire.
When the wire spool is finished it can be replaced
with a wire spool of 0.8Kg or 5.0Kg.
The wire is pushed by a roll (FIG..3, M) which is
moved by a series of mechanisms. The roll has
two grooves one marked by 0.9mm and the other
marked by 0.7mm. It is very important to use the
correct groove as explained at paragraph – " PRE-
PARATION FOR WELDING" – otherwise the wire will
not be fed regularly or it will be crashed; make sure
that the torch tip matches with the wire diameter.
Your welding power source is supplied with a torch
complete of tip for the wire included with the power
source. For all the other wire spools mount a tip that
matches with the wire diameter.
Make reference to figure 3 and follow the procedure
described at paragraph – " INSTALLATION OF THE
WELDING WIRE " for the replacement of the wire
spool.
WELDING TIPS
•
Keep the torch handle with an angle of 45°
with respect to the workpiece and maintain
the nozzle about 6mm from the surface.
•
Move the torch handle with prudence and
steadiness.
•
Avoid welding in areas with too much air.
The air that blows away the shielding gas
from the weld pool mainly causes porosity
in the weld.
•
Keep the wire and its cover clean. Do not
use rusted wire.
•
Avoid sharp bends and kinks on the welding
hose.
•
If possible, clean with compressed air the
wire liner when replacing the wire spool.
•
Periodically remove the dust, using low pressu-
re (3-4bar / 20-30 PSI) from the inside of the
power source, to assure adequate heat dissi-
pation from power source during operation.
SPOT WELDING
Spot welding is possible by replacing the welding
torch with a spot welding kit (not included). You can
buy the spot welding kit by any supplier of welding
material. Spot welding can be performed on carbon
steel sheets of 0.8mm thickness.
Place the spot welding nozzle on the upper sheet, push
the torch and press the trigger to point the first sheet
with the second one. For spot welding the machine
must be set at maximum current and maximum wire
speed. 0.8mm welding wire is suggestable.
ADJUSTMENT OF
THE POWER SOURCE
Set the voltage: use the correct "stick out". The wire
"stick out" is the distance between the contact tip
