THE FOLLOWING LEDS MAY BE SELECTED IN TIG
DC (DIRECT CURRENT) TIG AC (ALTERNATING CUR-
RENT) WELDING MODES:
that the display U displays the spot welding time that may
be adjusted from 0.1 to 30 seconds using the knob Y.
LED THAT MAY BE SELECTED ONLY IN TIG AC
(ALTERNATING CURRENT) WELDING MODE:
AO Start LED
Adjusts the "hot-start" level to maximize starts in
TIG AC mode for each electrode diameter. When
AL - Pre-gas LED
Range 0.05-2.5 seconds. Gas
output time before
begins.
AI - Welding start current LED.
This is a percentage of the weld-
ing current (LED AG).
AH - Slope up LED.
This is the time in which the cur-
rent, beginning from the mini-
mum, reaches the set current
value. (0-10 sec.)
AG - Main welding current LED.
AD - Second level of welding or
base current.
This current is always a percent-
age of the main current.
AE - Pulse frequency LED (0.16-
500 Hz).
When spot-welding is selected
(LED G) this LED lights to indicate
AF - LED
Adjusts the ratio between the
peak current time AG and the fre-
quency AE. t/T ( 10-90 % ) fig.4
Fig. 4
AC - Slope down LED.
This is the time in which the cur-
rent reaches the minimum and
the arc shuts down (0-10 sec.).
AB - Post-gas LED.
Adjusts the time gas escapes
after welding ends. (0-30 sec.)
this LED lights the display U shows a numerical value that
refers to the electrode diameters. The operator may use
the knob Y to set the diameter being used and obtain a
good start immediately. Range from 0.5 to 4.8.
LED AY Wave
welding Selects the welding waveform.
When this LED lights display U shows a number
corresponding to the selected waveform (see table).
11 = square - square
33 = delta - delta
13 = square - delta
21 = sine - square
31 = delta - square.
Default = square - sine (12).
This combination of numbers may be changed using the
encoder Y.
NOTE: The first number that makes up the figure refers
to the negative or penetration half-wave, the second
number refers to the positive or cleaning half-wave.
Changing the type of waveform may also reduce
noise in the arc in AC welding.
LED AN Hz
Adjusts the frequency of the alternating current.
Range 50-100 Hz.
LED AM Adjusts the wave balance.
Adjusts the percentage of the negative (penetra-
tion) half-wave in the alternating current period.
Range -10/0/10 where 0 = 65% (recommended) -10 =
50% and 10 = 85%.
< 48V
AC
LED T:
LED indicating that the device to reduce the risk of elec-
tric shock is in good working order.
Key H:
Pressing briefly activates synergy, where available,
and selects the LEDs I, L, M, S, and R ("briefly"
refers to less than 0.7 sec).
If the electrode diameter is not confirmed after the parame-
ters are selected, pressing this key briefly will exit synergy.

45°
If instead you wish to exit synergy after confirming the
electrode diameter, you must hold it down longer (mean-
ing more than 0.7 sec.).
Mat.
LED L: Material
The types of materials that may be selected are in relation
to the welding process and are:
In TIG AC mode aluminum (AL), magnesium (MG).
In TIG DC mode stainless steel (SS), copper (Cu), iron (FE)
and titanium (Ti).
22 = sine - sine
12 = square - sine
23 = sine - delta
32 = delta - sine
