Displaying The Software Version Installed; Electrode Welding (Mma); Tig "Ac" Welding - CEA MATRIX 3000 AC/DC R Operator's Manual

Displaying the software
version installed
The MATRIX AC/DC are fitted with a digital control with software
on board defined in the factory. This software is subject to contin-
uous evolution and improvement. The software is identified by a
specific number that can be viewed on the DISPLAY (D) as follows:
1) When the welding machine is off, push and hold the "MEM"
SAVE key down (T1).
2) Start the welding machine by turning the power supply switch
to position I.
3) For a few seconds the DISPLAY (D) shows the type of soft-
ware on board (e.g. b01) where:
• b indicates the welding machine model.
• 01 indicates the VERSION of the software installed

Electrode welding (MMA)

1) Start the welding machine by turning the power supply switch
to position I.
2) WELDING PROCESS SELECTION
Push the WELDING PROCESS SELECTION key (T7) to se-
lect the ELECTRODE welding processes for welding with
"HOT START" or "ARC FORCE" devices that can be pro-
grammed by the user.
3) Turn the ENCODER Knob (E) until the DISPLAY shows the
CURRENT VALUE at which you wish to weld, in relation to
the diameter of the electrode you are using.

4) WELDING PARAMETERS SELECTION
To refine the weld quality, the following parameters can be set
by pushing the WELDING PARAMETERS SELECTION key
(T10) in succession:
• HOT START - This increases the welding current, in per-
centage terms, for a time interval that can be set at the start
of the welding process, thereby reducing the risk of poor fu-
sion at the start of the joint (
• MMA ARC FORCE - Regulates, in percentage terms, the
dynamic characteristics of the arc (
00-100).

5) To exit these functions hold the WELDING PARAMETERS
SELECTION key (T10) down for about 1 second, after which
the DISPLAY INDICATION LED switches on and the welding
machine is once again ready to weld at the current indicated
on the DISPLAY (D).
6) Once the all the selections/regulations indicated above have
been made, welding can begin.
7) During the welding process the DISPLAY (D) shows the real
Amps (A) at which the operator is actually welding.

TIG "AC" welding

1) Start the welding machine by turning the power supply switch
to position I.
2) Push the WELDING PROCESS SELECTION key (T7) to se-
lect the TIG "HF AC" welding processes for TIG welding in
alternating current with high frequency (HF) ignition.
3) ELECTRODE DIAMETER SELECTION
Select the diameter of the electrode to achieve the best control
of ignition in a synergic manner. Selection is done by pushing
the ELECTRODE DIAMETER Key (T8) (ELECTRODE DIAM-
ETER LED flashing) and using the ENCODER Knob (E) to
regulate the value indicated on the DISPLAY (D).
