MMA method setting value of SOFT-START
Setting is the same as for hot-start, but turning the
encoder to the left (position 6, picture 2) sets the
negative value. In this way we set the percentage
decrease of starting current compared to the set. If
there is on the display value -30 it means that the
starting current will be about 30 % lower than the set
value. The reduction current can be adjusted by up to
90 %. After touching the electrode current unlike the
HOT START current continously increase the set value
lw for a set time.
MMA method – setting of the time value for SOFT-
START
Time setting for this function is the same as for the
HOT-START.
EXAMPLE:
1. When the set welding current 100 A (LED lw
position 10 in picture 1 and the LED MMA
(position 1, picture 1) the display shows 100
(100 A).
2. Pressing the SET button the LED% will light up
(position 11, picture 1). It is possible to set the
value of starting current - SOFT START for
example 50 % lower (we set potenciometer on
the display -
current" will be 50 A. SOFT START function can
be disabled by setting to 0 %.
3. Again by pressing the SET button with LED
(position 4, picture 1). It is possible to set the
value of an encoder activation period starting
current - eg 1.0 s.
4. When you start welding the arc is ignited by 50
A current for 1.0 s will steadily increased to the
set value Iw 100 A.
METHOD MMA - security function V.R.D.
The security system V.R.D. provides a low voltage at
the output of the machine - 15 V. This safe value
changes immediately after contacting the electrode
with the welded material. When the welding process
is finished the output voltage will automatically
change to 15 V again. When the V.R.D. function is
turned off the open circuit voltage is 88 V.
Method MMA - switching on function V.R.D.
Switch off the machine with the main switch. Press
and hold button MET (pos. 6, pict. 1) on the front
panel and switch on the machine with the main
switch. Release button MET just after switching on.
LED diode MMA V.R.D. (pos. 7, pict. 1) is lit up on
the panel and sign ON is displayed for about 1-2 sec.

Method MMA - switching off function V.R.D.
Switch off the machine with the main switch. Press
and hold button MET (position 6, picture 1) on the
front panel and switch on the machine with the main
switch. Release button MET just after switching on.
Indicator light LED V.R.D. is switched off on the front
panel and sign OFF is displayed for about 1-2 sec.
Function V.R.D. is switched off.
OPTIONS FOR PARAMETERS SETTING FOR TIG
METHOD:

Welding current 10-150 A (serie 160), 10-190 A
(serie 200).
