4 - WELDING
During the welding the display shows the values, if possible mea-
sured, of the active parameters, based on the type of welding pro-
cess, memorised within the selected JOB.
As already indicated, the parameters can be viewed by pressing
and releasing the PARAMETER SELECTION key - A (T1) or in al-
ternative the PARAMETER SELECTION key - V (T4), while the
SPECIAL FUNCTIONS “Fx” key (T3) of “first level” contained within
each individual JOB can be viewed (but not modified) by simply
keeping the SPECIAL FUNCTIONS “Fx” key (T3) pressed for a
duration of about 3 seconds.
5 - HOLD
This function automatically starts itself at the conclusion of every
welding operation and it is indicated to the operator by means of a
flashing light of the HOLD FUNCTION LED for a specific amount
of time.
Once the welding has been terminated, for about 15 seconds, both
the DISPLAYS should show the same values of the parameters
during the welding.
To interrupt the HOLD function and go back to the PRESETTING
phase before 15 seconds have passed, simply turn one of the two
ENCODER (E1-E2) knobs.
E1 E2
The HOLD function can be terminated ahead of time even once
again starting the welding.
Once 15 seconds have passed (HOLD FUNCTION) the TX con-
trol panel goes back to the PRESETTING phase.
6 - MODIFICATION AND OVERWRITING OF A
MEMORISED JOB
To edit and overwrite a JOB proceed as follows:
1) Select JOB, pressing and releasing, even various times if ne-
cessary, the WELDING PROCESS SELECTION key (T2) un-
til the corresponding LED lights up.
2) Select the individual JOB to modify and overwrite rotating the
ENCODER knob - V (E2).
3) Bring up and activate the JOB, loading its settings in the wel-
ding process it comes from, keeping the SAVE “MEM” key (T2)
pressed for a duration of about 3 seconds.
4) Acquire the parameters necessary for editing the JOB.
5) Hold the SAVE “MEM” key (T2) down for at least 3 consecuti-
ve seconds until both displays show the flashing wording that
represent the first AUTOMATIC WELDING POINT (JOB) free
and/or available to the operator that can be used for saving
the data.
6) Rotate the ENCODER knob - V (E2) until identifying the indi-
vidual JOB that will be overwritten.
7) Keep pressed, for at least 3 consecutive seconds, the SAVE
“MEM” key (T2) to confirm and make the operation effective.
7 - DELETING A JOB SAVED
In JOB mode, holding down the PARAMETER SELECTION - A
(T1) and PARAMETER SELECTION - V (T4) keys down simul-
taneously for about 5 seconds deletes the current automatic wel-
ding point.
T1 T4
The control panel automatically goes to the first JOB saved or re-
ads “ no JOB ” is no JOBS have been saved.
Error condition
This paragraph describes the error conditions that may arise on
the welding machine, the codes and messages shown on both TX
operator interface displays, and the diagnoses for attempting to
correct and resolve them.
In an “error condition” the operator’s interface uses both displays
to display:
