TIG AC - Setting PRE-GAS function
(gas pre-flow)
The function serves to provide a protective atmosphere
against ignition welding arc. Pressing the control button
on the burner activates the function that is active for
the set time. After the set time has elapsed, the welding
arc ignites. Activation is done by pressing the control
n-coder one after the other.

TIG AC - Setting START CURRENT func-
tion
The function allows setting the starting current which is
activated when the arc is ignited. The function setting
eliminates burn-through of the material to be welded
by immediately starting the main welding current. Acti-
vation is done by pressing the control n-coder one after
the other.

TIG AC - Setting UP SLOPE function
(smooth start)
The function allows to set a continuous increase of cu-
rrent from the START CURRENT function to the main
welding current. Influence This function gradually heats
up the beginning of the weld and eliminates the bur-
ning of the welded material. Activation is done by pre-
ssing the control n-coder one after the other.

TIG AC - Setting DOWN SLOPE function
The function is used for the continuous termination of
the welding process. Together with the END CURRENT
function, it prevents the crater from forming at the end
of the weld when properly adjusted. During the set
time the welding current decreases to the value of the
end current. Activation is done by pressing the control
n-coder one after the other.
