5. TIG Calotte / electrode diameter (only for AC machines (LED 20)
Here, the calotte diameter (ball) used in TIG AC or the electrode diameter
in TIG DC can be adjusted, so that the machine can use the optimum ignition
parameters at start up. Tap on the key diameter (item 5), LED flashes,
and select with the knob (item9) the used diameter. Tap again on the key
diameter (item 5), LED stops flashing.
The following diameters can be adjusted: 1.0 to 4.0mm in different steps.
The calotte diameter should be less than or equal to the electrode diameter.
The lager the diameter of the calotte is, the higher is the energy of the starting pulse.
NOTE: If the diameter is too large, parts of the tungsten electrode can cut off at the Start!
In this case, the calotte diameter has to be reduced by one level,
to reduce the wear of the electrode.
6. Display
The display shows the actual welding current during welding.
In standby mode, all parameters can be set via the display.
7. AC wave type (only for AC machines in welding process AC (LED 20)
It is possible to select 4 different waveforms for aluminium welding depending on
the field. By tapping on the button AC wave type (item 7), it is possible to switch
between the wave forms. The corresponding LED is light.
The display shows always the mean value of the current.
1. Square (LED 70):
all sheet metal thicknesses, high arc stability, high cleaning efficiency, higher noise levels
2. Mixed (LED 71 is light) / 3. Triangle (LED 71a is flashing):
for thin to medium sheet metal, longer service life of the electrode, normal cleaning effect, better thermal
control of the arc – Triangle value from 16A to 127A / 173A (mean value) / (peak = 220A / 300A)
4. Sinus (LED 72):
for thin to medium sheet metal, low noise levels, normal cleaning effect, smooth arc,
suitable for butt welding
Sinus value adjustable from 16A to 154A / 212A (mean value) / (peak = 220A / 300A)
8. Pulse type
By tapping on the button pulse type (item 8), it is possible to switch between the pulse types.
The corresponding LED lights.
3 different pulse types are available:
1. Pulse AUTO (LED 80) – only for welding process DC:
In automatic pulse method it is possible to set a pulse frequency from
30Hz to 500Hz. In this method of pulse welding, the welding current is
automatically adjusted to the pulse frequency and vice versa.
The setting of the parameters is described under Point 4 - functions.
In DC process the following parameters can be set:
Pulse main current Ip: 25 – 220/300A (corresponds main current I1)
Pulse base current Ib: 5 – 60A
Pulse frequency f:
2. Pulse SPEED (LED 81) – only for welding process DC:
In the fast SPEED pulse method, a pulse frequency of 0.5 Hz to 2000 Hz (2 kHz) can be set.
The setting of the parameters is described under Point 4 - functions.
In DC process the following parameters can be set:
Pulse main current Ip: 5 – 220/300A (corresponds main current I1)
Pulse base current Ib: 5 – 220/300A
Pulse frequency f:
3. Pulse MAN (LED82) – for welding process DC and AC:
In the manual pulse method, a slow pulse frequency (1Hz to 10Hz or 100Hz) can be adjusted.
The setting of the parameters is described under Point 4 - functions.
In DC process the following parameters can be set:
Pulse main current Ip: 5 – 220/300A (corresponds main current I1)
Pulse base current Ib: 5 – 220/300A
Time pulse current Tp: 0.01 – 0.99s (100Hz – 1Hz)
Time base current Tb: 0.01 – 0.99s (100Hz – 1Hz)
