THE FOLLOWING LEDS MAY BE SELECTED IN TIG
DC (DIRECT CURRENT) TIG AC (ALTERNATING CUR-
RENT) WELDING MODES:
AL - Pre-gas LED
Range 0.05-2.5 seconds. Gas
output time before welding
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
that the display U displays the spot welding time that may
be adjusted from 0.1 to 30 seconds using the knob Y .
AF - LED
Adjusts the ratio between the
peak current time
AG and the fre-
quency AE . t/T ( 10-90 % ) 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.)
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
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
Selects the welding waveform.
When this LED lights display
U shows a number
corresponding to the selected waveform (see table).
11 = square - square
22 = sine - sine
33 = delta - delta 12 = square - sine
13 = square - delta 23 = sine - delta
21 = sine - square 32 = delta - sine
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%.
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.
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.).
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).
