DC Stick (SMAW) Welding
To start DC Stick welding process:
1. Set polarity
2. To select Stick welding:

Soft
Press MODE several times until the LED above lights up
(led ON) is turned on.
When the Stick position is selected, the following welding
features are enabled:
Hot Start: This is a temporary increase in the output
current during the start of the stick welding process.
This helps ignite the arc quickly and reliably.
Anti-Sticking: This is a function which decreases the
output current of the machine to a low level when the
operator makes an error and sticks the electrode to
the work piece. This decrease in current allows the
operator to remove the electrode from the electrode
holder without creating large sparks which can
damage the electrode holder.
Auto Adaptive Arc Force: this function increases
temporary the output current, used to clear intermittent
connections between the electrode and the weld
puddle that occur during stick welding.
This is an active control feature that guarantees the
best arrangement between the arc stability and spatter
presence. The feature "Auto Adaptive Arc Force" has
instead of a fixed or manual regulation, an automatic
and multilevel setting: its intensity depends by the
output voltage and it is calculated in real time by the
microprocessor where are also mapped the Arc Force
levels. The control measure in each instant the output
voltage and it determines the amount of the peak of
current to apply; that value is enough to breaks the
metal drop that is being transferred from the electrode
to the workpiece as to guarantee the arc stability, but
not too high to avoid spatters around the welding
puddle. That means:
Electrode / workpiece sticking prevention, also with
low current values.
Spatters
reduction.
The welding operations are simplified and the welded
joins looks better, also if not brushed after the welding.
In Stick mode, two different setup are available, and they
are completely separate into Process setup:
SOFT Stick: For a welding with a low spatter
presence.
CRISP Stick (Factory Default): For an aggressive
welding, with an increased Arc stability.
For default the polarity is DC+. To change in DC- see
menu SMAW operation section.
See menu SMAW to change value of hot start and arc
force.
AC Stick Welding
To start AC Stick welding process:
1. Set polarity

Press MODE several times until the LED above lights up
(led ON) is turned on.
By default the output current wave form is a 60Hz
sinusoidal current with balance 50% without offset.
Accessing to AC wave shape it is only possible change
the frequency.
Indicators AUTO, EN/EP and Balance are OFF.

DC TIG Welding
To start DC Tig welding process:
1. Set polarity
2. To select TIG welding:

Lift
HF
Press MODE several times until the LED above lights up
Led 2T
turned on for default.
LIFT TIG
When the mode pushbutton is in the Lift TIG position, the
machine is ready for Lift TIG welding. Lift TIG is a method
of starting a TIG weld by first pressing the TIG torch
electrode on the work piece in order to create a low
current short circuit. Then, the electrode is lifted from the
work piece to start the TIG arc.
HF TIG
When the mode pushbutton is in HF TIG position, the
machine is ready for HF TIG welding. During the HF TIG
mode, the TIG arc is started by HF without pressing the
electrode on the work piece. The HF used for starting the
TIG arc will remain on for 3 seconds; if the arc is not
started in this time limit, the trigger sequence must be
restarted.
