setting of welding parameters
setting the welding method
the selection and confirmation of the welding method is carried out using the
control button.
MMA - the method is designed for welding with a coated electrode crNi, al,
alloys and steel materials.
TIG LIFT - the method is designed for welding of crNi and steel materials with
dc current. it also allows soldering.
MIG/MAG - the method is designed for welding of steel, crNi and al materi -
als. it also allows soldering cusi.

MMA - Welding current setting
the welding current is set using the control n-coder.

MMA - setting the hoT sTART function (easier ignition)
the function allows setting the value of the welding current increase when the
arc is ignited. the function facilitates ignition of the welding arc. the function
is set in the range of 0 - 10, which sets its intensity (0 = off; 10 = maximum). to
activate, press the FuNctioN (Fn), select button the function is performed by
sequentially rotating the control n-coder i, setting the function parameter by
pressing the control n-coder ii. press FuNctioN (Fn) again to exit / confirm the
setting.

MMA - setting the ARC FoRCe function
the function increases the energy supplied to the shortening arc by the mma
method, thereby accelerating the electrode melting and preventing it from
sticking. the function is activated when the arc voltage drops below approx.
17 v. setting the value determines the possible increase in welding current.
the function is set in the range 0 - 10, which adjusts its intensity (0 = off; 10 =
maximum). to activate, press the FuNctioN (Fn), select button the function is
performed by sequentially rotating the control n-coder i, setting the function
parameter by pressing the control n-coder ii. press FuNctioN (Fn) again to
exit / confirm the setting.

MMA - setting the ANTI sTICK function
(sticking electrode)
the function reduces the welding voltage to 5 v when evaluating the short -
-circuit at the output terminals (when the electrode is glued to the material
to be welded), thus allowing easy removal of the electrode from the ma -
terial to be welded. the function is automatically activated each time the
machine is switched on.
TIG DC lIFT - Welding current setting
the welding current is set using the control n-coder.

tiG dc liFt N-coder
TIG DC lIFT - setting the DoWN sloPe function
the function is used for the continuous termination of the welding process.
together with the eNd curreNt function, it prevents crater formation at
the end of the weld when properly adjusted. during the set time, the wel -
ding current drops to the value of the end current. the function is set in the
range of 0 - 10, which sets its intensity (0 = off; 10 = maximum). to activate,
press the FuNctioN (Fn), select button the function is performed by sequen -
tially rotating the control n-coder i, setting the function parameter by pressing
the control n-coder ii. press FuNctioN (Fn) again to exit / confirm the setting.
