Furthermore, switch 10 adjusts the
parameters shown in the figure below:
ADJUSTMENTS AND SETTINGS:
Button 10 adjusts the welding settings on the
screen:
Arc Force: Used to set the increase in current
as a percentage of
the welding current, which the welder can
provide to keep the arc fully ignited.
Hot start: Used to set the current increase as
a percentage of the welding current, which the
welder can provide at the time the arc is struck.
Hot start span: Used to set the time during
which the hot start current is provided.
Remote ctrl: Used to switch on (ON) or switch
off (OFF) the remote control of the intensity of
the current delivered.
10. WELDING TABLE
Use the table below to calculate the
welding current, according to the type of
electrode used:
11. CONNECTION FOR MMA WELDING
The Dinse connector is inserted by
lining-up the key with the groove and
turning the connector in a clockwise
direction until it stops.
The electrode clamp holder and earth must
be connected to the ‘+’ and ‘-‘ terminals,
according to the specifications of the
electrodes used.
12. IGNITING THE MMA ARC
OFF
This is carried out by stopping a while over
the last crater (i.e. the end of the welding
seam), returning slowly on the previously
deposited seam for approximately two
centimetres and, only at this point, moving
the electrode away from the workpiece to
turn off the arc.

Create the contact for
igniting the arc at a
distance of
approximately 5 cm from
the initial welding point.
Immediately move the
electrode towards the
workpiece, without touching
it, in order to keep the arc
ignited.
Quickly bring the
electrode, without turning
off the arc, towards the
point where the welding
seam will begin.
Begin welding, advancing
slowly. The distance
between the tip of the
electrode and the
workpiece must be as
identical as possible to the
diameter of the electrode
in use.
