Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder's pressure rollers. It is important that the
pressure is not too great.
Fig 1
To check that the feed pressure is set correctly, you can feed out the wire against
an insolated object, e.g. a piece of wood.
When you hold the gun approx. 5 mm from the piece of wood (fig. 1) the feed
rollers should slip.
If you hold the gun approx. 50 mm from the piece of wood, the wire should be
fed out and bend (fig. 2).
6.6 MIG process set- -up guide
In the following table recommended welding settings are shown, depending on the
joint type, workpiece thickness and filler wire diameter.
To set machine for welding:
find the plate thickness (T) and type of joint,
S
find the diameter (d) of the filler wire,
S
in the column corresponding to the appropriate material and shielding gas find
S
the suggested arc voltage and wire feed setting; for spot welding find additionally
recommended time setting,
set arc voltage with knobs [3], [3a] and wire feed speed with knob [7].
S
NOTE: The given recommendations only serve as rough guide for the operator, optimal
set--up may differ from the one in table. It depends on mains voltage deviation, precision of
the wire speed setting, applied welding techniques, welding position, shielding gas etc.
If needed, some corrections of the arc voltage and wire speed may be tried out for
satisfactory results.
