8. Power Inverter Running LED:
MMA welding: This lights up when the unit is
ready to weld.
TIG welding: This lights up as soon as an arc is
created.
9. Display panel: The welding current setting is
displayed.
The following information will also be displayed:
- When unit is switched on, welder model and
firmware information.
- Should the letters 'E.Ln' appear on the display
and the LED 4 lights up, it means the power
supply is below the standard required.

3. 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.
4. IGNITION OF THE MMA ARC
IGNITION
Create
igniting the arc at a distance
of approximately 5 cm from
the initial welding point.
Immediately
electrode
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.
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.

5. TIG WELDING

To choose this method of welding press
the MODE button (13 fig. 1) until the
display shows the indication of welding
technology choice.
Inert gas (Argon) welding with an infusible
Tungsten electrode and arc (often call TIG
(Tungsten Inert Gas) for short, is a welding
procedure whereby the heat is produced by an
arc that strikes between a tungsten electrode
(which is not consumable) and the workpiece.
The welding is carried out by fusing the edges of
the workpiece or by adding other filler material
using specific types of rod to create a joint. The
torch is ignited by touching the workpiece with the
electrode and then lifting. The TIG procedure can
be adapted to any work position and can also be
applied to very thin sheets of metal (0,2-0,3 mm).
The TIG procedure is distinguished by the ease
with which the arc can be controlled, a powerful
and concentrated thermal source and the simple
manner in which the filler material can be
controlled.
