display O shuts off and the display U displays a message
corresponding to the material to be welded (see descrip-
tion of LED L). Turn the knob Y to choose.
Pressing the button H again confirms the choice of mate-
rial and causes the LED M to light. The display U shows
the welding positions available (see description of LED
M).
Turn the knob Y to choose. Pressing the button H again
confirms the choice of position and causes the LED S to
light. The display O shows the set current, while the dis-
play U shows the thickness in millimeters that corre-
sponds to the current (see description of LED S).
Pressing the button H again confirms the choice of thick-
ness and causes the LED R to light.
One or more electrode diameters are proposed based on
the set choice of material, position, thickness and current.
The recommended electrode will be proposed first and
the numerical value of the diameter will always be steadi-
ly lit, next to the letter A if the amp setting selected for
welding falls within the current range of two diameters;
the second choice of electrode diameter will be proposed
only if the encoder Y is turned. The second choice will
also be displayed steadily lit. If you turn the encoder fur-
ther, the display U shows the diameter above the second
choice and below the first choice, flashing.
Given that the electrode diameter mainly defines the start
level AO and the minimum current AI, the operator may
choose a combination that is not recommended.
At this point the operator has two choices:
1. To exit synergy without confirming the choices made.
To do so, briefly press the button H; the LED I shuts off
and the panel displays the settings in effect before you
entered synergy.
2. Confirm the synergy by pressing the button H for
longer than 0.7 sec. At this point all synergy functions are
set and, if selected using the button AP, the display U
shows the message "AU" (automatic).
The LED I remains lit to confirm that the parameters have
been set.
To summarize, when you confirm the electrode diameter
(by holding down the button H when the LED R is select-
ed) the start, wave, Hz, balance and current AI functions
are arranged according to the automatic logic described
previously. When the electrode is confirmed, the LED R
shuts off and the LED I lights.
4 REMOTE CONTROLS
The following remote controls may be connected to
adjust the welding current for this welding machine:
Art.1256 TIG torch button only (water-cooled).
Art.1258 TIG torch UP/DOWN (water-cooled).
Art. 193 Foot control (used in TIG welding)
Art 1192+Art 187 (used in MMA welding)
Art. 1180 Connection to simultaneously connect the torch
and the pedal control. Art 193 may be used in any TIG
welding mode with this accessory.
Commands that include a potentiometer regulate the
welding current from the minimum to the maximum
current set via the knob Y.
Commands with UP/DOWN logic regulate the welding
current from the minimum to the maximum.
The remote control settings are always active in the PL
program, while they are not active in a saved program.
