Method TIG - setting of pulse frequency of welding
current
Press button SET (position 9, picture 1) until LED
PULSE (position 5, picture 1) is on as in the picture.
Set up required value of pulse frequency of welding
current with a potentiometer. Pulse is switched off
with setting-up „0".
Method TIG - setting of time of welding current run-
out
Press button SET (pos. 9, pict. 1) until LED SLOPE
(pos. 7, pict. 1) is on as in the picture. Set up required
value of time duration of welding current run-out
with a potentiometer.
Method TIG - setting of end current value
Press button SET (pos. 9, pict. 1) until I end is on as in
the picture. Set up required value of end welding
current with a potentiometer.
EXAMPLE:
1. When you set welding current on 100 A (LED Iw
is on, position 10, picture 1), and LED TIG
(position 2, pict. 1), display shows 100 (100 A).
2. When you press button SET, LED PULSE is lit up
(pos. 5, pict. 1). It is possible to set the value of
pulse frequency of welding currant within range 0
(pulse is switched off) up to value 500 Hz.
Function PULSE can be switched off, if you set
frequency on "0". If you press button SET again,
LED DOWN SLOPE is lit up (pos. 7, pict. 1). It is
possible to set value of run-out time of welding
current - for example 1 sec (you can set it with a
potentiometer on display 1). Time of run-out of
starting current is 1 sec.
3. If you press button SET again, LED I
(position 8, picture 1). It is possible to set value
of end welding current - for example 10 A (it can
be set with a potentiometer on display 10). Time
of end welding current is 10 A.
OVERHEATING OF THE MACHINE
°C signs on the display signalize overheating of the
machine. Signalization is two stage signalization. In
the first phaze the title is, the machine is working
properly, but if the working process will not be
interupt, the machine will be blocked (°C lights for all
the time) until the inside part will cool down.
ARC-FORCE
This feature increases the energy supplied to the
shortening of the arc in MMA method which
accelerates melting electrodes and thus prevents its
sticking. The function is activated when the arc
voltage drops below approximately 15 V.
The function can be changed by rotating the encoder
in three steps when starting the machine is in MMA
mode (AF0, AF1 and AF2). When setting AF0 the
function is off and there is no increase in current.
When AF1 the additional energy is 50% and at setting
AF2 is 100%. To change the settings for this function
can be performed even when the machine is running,
in a way that for more than 2 sec. hold the SET
button (position 9, picture 1). Switching function is
signaled by LED MMA AF.
ANTI-STICK
Signalization - - - the display indicates the function of
impressing by ANTI STICK. The function is activated,
after all when it comes to the action and contact
between the electrode and material material
(feature does not prevent sticking). By touching is
reduced current below 10 A and thus allow easy peel
off the electrode. Anti-stick function can be
deactivated eg. for drying of electrodes and this for
more than 4 s hold the SET button (position 9,
picture 1), and then set the switch rotary encoder.
Function of undervoltage (Uin)
The machine is equipped with an undervoltage
recognizing of el. network. Upon the occurrence of
-38 -
is lit up
