Control Panel - Migatronic FOCUS TIG 160 DC HP Betriebsanleitung

Digital display
The control panel is equipped with a
display showing the welding current. During
standby the pre-set welding current is displayed,
while the actual welding current is shown during
welding.
Disconnection error
The overheating indicator is illuminated
if welding is interrupted due to overheating of the
machine. When the situation is back to normal,
the machine will reconnect automatically.
Therefore, welding cables must be placed so the
risk of unintended establishment of the arc is
avoided during reconnection.
Welding voltage
The welding voltage indicator is
illuminated for reasons of safety and in order to
show if there is voltage at the output taps or
electrode.
Welding current
Welding current is adjusted by
means of this control knob. The
current is adjustable from 10 A to
160A. The adjusted value is shown in the
display.
Function switch
This switch is used for selection of
MMA or TIG welding, ignition
method in TIG welding and two-
times or four-times ignition in TIG welding.
This symbol indicates MMA welding.

CONTROL PANEL

This symbol indicates TIG welding.
Two-stroke HF-ignition:
This symbol means contact-free
striking. The arc is established in the following
way:
The torch is placed so that the Tungsten elec-
trode is quite close to the welding spot (1 or 2
mm).
2) The torch trigger is activated and must be
kept pressed down. The high voltage
generator of the machine will produce a
voltage impulse that ignites the arc. The
welding process has started. The welding
process will stop when the torch trigger is
deactivated. The arc will extinguish after the
period of slope-down time.
Four-stroke HF-ignition:
This symbol means contact-free
striking. The arc is established in the following
way:
1) The torch is placed so that the Tungsten
electrode is quite close to the welding spot (1
or 2 mm).
2) The torch trigger is activated and de-
activated, and the high voltage generator of
the machine will produce a voltage impulse
that ignites the arc.
In order to stop the welding process the
trigger must be activated again after which
the slope-down period begins. The arc will
extinguish after the period of slope-down
time, and the trigger is deactivated. The
welding current is immediately stopped and
the arc extinguished if the torch trigger is
released before the slope-down period is
finished.
Two-stroke LIFTIG:
This symbol means LIFTIG ignition. The
arc is established in the following way:
1) The torch is placed so that the Tungsten
electrode has contact with the welding spot.
2) The torch trigger is activated and must be
kept pressed down.
