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 „I
w
“ is
on, pos. 10, pic. 1) and LED „TIG“ (pos. 2, pict. 1), dis
-
play shows 100 (100 A).
2. When you press button SET, LED „PULSE“ is lit up
(pos. 5, pic. 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, pic. 1). It is possible to set value of run-out
time of welding current - for example 1 s (you can set
it with a potentiometer on display 1). Time of run
-
-out of starting current is 1 s.
3. If you press button SET again, LED „I
END
“ is lit up (pos.
8, pic. 1). It is possible to set value of end welding
current - for example 10 A (it can be set with a poten
-
tiometer on display 10). Time of end welding current
is 10 A.
Overheating of the machine
°C signs on the display signalize overheating of the ma
-
chine. 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 shor
-
tening 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 s. hold the SET button (pos. 9, pic. 1). Swit
-
ching function is signaled by LED „MMA AF“.
ANTI STICK
Signalization - - - the display indicates the function of
impressing by ANTI STICK. The function is activated, af
-
ter 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 be
-
low 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 (pos. 9, pic. 1), and then set the switch rotary
encoder: AS 0 function is disabled, AS 1 function is
active.
Function of undervoltage (Uin)
The machine is equipped with an undervoltage reco
-
gnizing of el. network. Upon the occurrence of deep
undervoltage during the operation is drawing attention
by blinking Uin. After remission of the causes removes
the message using the main switch (pos. 1, pic. 2).
WARNING: If the machine is powered by a lower vol
-
tage than 230 V, proportionally there is a decrease per
-
formance of the machine.
