Position 7 Potentiometer of welding current.
Position 8 Digital panel (only TIG LA).
Position 9 Switcher of remote control.
Position 10 MMA/TIG method switcher.

Connection of the welding cables

With the machine disconnected from the supply,
connect the welding cables, welding torch and earth-
cable. The polarity must be choosen according to
welding method. For MMA method the polarity
determines the producer of electrodes according to
their type. The welding cables should be as short as
possible, close to each other, and positioned at floor
or close to it.
WELDING PART
The part to be welded must always be connected to
earth in order to reduce electromagnetic emission.
Much attention must be afforded so that the earth
connection of the part to be welded does not increa-
se the risk of accident to the user or the risk of dama-
ge to other electric equipment. When it is necessary
to connect the part to be welded to earth, you should
make a direct connection between the part and the
earth shaft. In thouse countries in which such a
connection is not allowed, connect the part to be
welded to earth using suitable capacitors, in
compliance with the national regulations.

machines 150 TIG LA - 170 TIG LA
SETTING OF WELDING METHOD
After switching the machine on, one from diodes of
welding method light up (the last you set before
switching off). By pressing button MET (pos. 2, pic. 1),
you can choose the other method.
SETTING PARAMETERS FOR MMA METHOD ARE THE
FOLLOWING:

Welding current 10-150 A (series 150), 10-170 A
(series 170).

Value of „increase of welding current" HOT-
START 0 (HOTSTART switched off) up to 70% of
welding current, max. 150 A (series 150), 170 A
(series 170).

Time of run-out of „starting current" 0,1 - 1 s.
Method MMA - setting of welding current
Set up required value of welding current with a
potentiometer (pos. 7, pic. 2).
Method MMA - setting of value HOTSTART
Press button SET (pos. 3, pic. 1) until LED % (pos. 4,
pic. 1) is on as in the picture. Set up required value of
current increase in % with a potentiometer (pos. 7,
pic. 2). If there is value 30 on the display it means
increase of start current by 30 %.
