The welding process ends after the
preset down-slope time.
TIG 4 CYCLE
Operating mode for TIG welding in 4
cycle mode:
− Press the forward pushbutton (start/
stop pushbutton).
The welding process starts.
− The arc will burn at the preset
start current while the forward
pushbutton (start/stop pushbut-
ton) is held down.
− After releasing the pushbutton,
the current slopes up to the pre-
set welding current within the pre-
set up-slope time.
If the current reaches the preset
down-slope current while sloping
up in operating mode TIG Puls-
ing, pulsing automatically will
begin with the preset parameters
(see "Pulsed Arc Welding").
− Actuate the forward pushbutton
again.
The welding current falls down to
the preset end current within the
preset down-slope time.
If the current reaches the preset
down-slope current while sloping
down in operating mode TIG Puls-
ing, pulsing is automatically deacti-
vated.
− The arc will burn at the preset
end current while the forward
pushbutton is held down (end
crater filling).
− Releasing the button ends the
welding process.
TIG 2 CYCLE + HF
Operating mode is same as TIG welding
in 2 cycle mode, but with HF ignition.
TIG 4 CYCLE + HF
Operating mode is same as TIG welding
in 4 cycle mode, but with HF ignition.
Slope up/down function
Note:
When using a TIG torch with
function button, the welding current can
be reduced to 50 % while welding.
− Press the rear pushbutton (function
button).
The arc will burn at 50 % of the pre-
set welding current while the rear
pushbutton is held down.
− When the button is released the
welding current slopes back up to its
preset value.
TIG AC 2 CYCLE
(WIG 162 AC/DCsi only)
Operating mode is same as TIG welding
in 2 cycle mode, but with an AC welding
voltage and HF ignition.
TIG AC 4 CYCLE
(WIG 162 AC/DCsi only)
Operating mode is same as TIG welding
in 4 cycle mode, but with an AC welding
voltage and HF ignition.
5.2 Parameter
By turning the "Parameter selection"
knob in the selected operating mode,
you reach the parameters which can be
changed (see "Menu Structure" ).
In the display the parameter name and
the currently set value will appear. With
the "Parameter adjustment" knob you
can change the value displayed.
WELDING CURRENT
Maximum current for the actual welding
process.
Setting range: 5 A...160 A.
Note:
During welding the
diplay shows this value by default. Turn-
ing the "Parameter adjustment" knob
during the welding process changes the
welding current immediately.
If a remote control unit is connected to
the machine, the welding current can be
regulated with it from 5 A up to the pre-
set welding current value.
Example: The preset welding current is
100 A. With the remote control unit the
welding current can then be regulated
from 5 A to 100 A.
Note:
Do not use a hand- or foot-oper-
ated remote control unit together with a
TIG torch with integrated welding current
regulator!
This may result in undesired current set-
tings, causing inaccurate
results.
START CURRENT
The current at which the machine starts
the welding process.
Setting range: 5 A...160 A.
END CURRENT
Current level to which the welding cur-
rent slopes down for crater filling at the
end of the welding process.
Setting range: 5 A...160 A.
UP-SLOPE TIME
Period in which the current slopes up to
the max. welding current.
Setting range: 0.0 s...10.0 s.
DOWN-SLOPE TIME
Period it takes the welding current to
slope down to the end current.
Setting range: 0.0 s...10.0 s.
GAS PRE-FLOW
Period the shielding gas will flow before
the welding process starts.
Setting range: 0.0...10.0 s.
GAS POST-FLOW.
Period the shielding gas will flow after
the welding process has ended.
Setting range 0.0s...10.0 s.
PULSER ON / PULSER OFF
By turning the "Parameter adjustment"
knob the pulser is alternately activated
and deactivated.
If "PULSER ON" is activated, the follow-
ing parameters can be accessed by turn-
ing the "Parameter selection" knob:
FREQUENCY
Pulse frequency
With
frequency [Hz] = duration [sec]
duration of the pulse can be calcu-
control's
lated.
Setting range: 0.3 Hz...600 Hz.
Setting in the range
of:
0.3 Hz bis 10.0 Hz
10 Hz bis 100.0 Hz
100 Hz bis 600.0 Hz
PULSE RATIO
The ratio of welding current time to
the base current time.
Example: A setting of 10 % means
that for 10 % of the pulse time the
welding current and for 90 % of the
pulse time the base current is
applied.
Setting range: 10 %...90 %.
welding
PULSE BASE CURRENT
Current in the second half of a
pulse.
Setting range: 5 A...160 A.
BALANCE
(WIG 162 AC/DCsi in operating mode
TIG AC ... only)
Ratio of positive to negative voltage time
for AC welding. A value of for instance
30 % means that for 30 % of the dura-
tion (t ) of a period (T) the welding volt-
1
age at the electrode will be positive and
for the remaining 70 % (t
