Method TIG - setting of time of welding current run-
out
Press button SET (pos. 3, pic. 1) until LED SLOPE (pos.
9, pic. 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. 3, pic. 1) until I
END
(poz. 7, pic.
1) 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, pos. 6, pic. 1, and LED TIG pos. 10, pic. 1),
display shows 100 (100 A).
2.
When you press button SET, LED PULSE is lit up
(pos. 8, 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. 9, 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 value 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. 7, pic. 1). It is possible to set value of end
welding current - for example 10 A (it can be set
with a potentiometer on display value 10). Time
of end welding current is 10 A.
OVERHEATING OF THE MACHINE
Err on display indicates overheating of the machine.
ANTISTICK
Symbols “- - -“ on display signals activity of function
ANTISTICK.
WELDING IN METHOD TIG
If you want to strike arch in TIG method, you must
follow these instructions:
1.
Switch the inverter on by the main switch. Set
welding method TIG and parameters of welding
according to the instruction above.
2.
Machines LA - connect welding torch to inverter
and to cylinder pressure regulator on gas bottle.
Welding torch is in “-“ connector, earth-cable in
“+” connector.
3.
Using the valve on the torch, switch on gas - Ar-
gon (for machines LA).
4.
Touch earthing material with wolfram electrode.
Inverter source will be switched on automatical-
ly (only TIG LA).
5.
With rolling movement over the edge of the
hose, you shall remove tungsten electrode - el.
arch burns in case you want to finish welding
process, remove the electrode for a short
moment (up to 1 s) for the distance of 8-10 mm
from welding material. Inverter will decreese
automatically welding current (according to
adjusted time DOWN SLOPE) until welding arc is
completely switched off - (according to adjusted
value of end current I
END
).
