Control Panel - Migatronic FOCUS TIG 160 DC HP PFC Manuel D'instruction

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.
This symbol indicates TIG welding.
Two-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 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.

CONTROL PANEL

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 deactivated, 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.
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.
3) The arc is established by lifting the torch, and the welding
process has started. In order to stop the welding process,
the torch trigger is deactivated. The arc will extinguish after
the period of slope-down time.
1) The torch is placed so that the Tungsten electrode has

Four-stroke HF-ignition:
This symbol means contact-free striking. The arc is
established in the following way:
Two-stroke LIFTIG:
This symbol means LIFTIG ignition. The arc is
established in the following way:
Four-stroke LIFTIG:
This symbol means LIFTIG ignition. The arc is
established in the following way:
Pulse welding
This key pad is used for shift between welding
without pulse and pulse welding. Base amp,
pulse time and base amp time are adjusted to
the requested values during pulse welding by
using the respective key pads.
Base amp
Base amp is set in per cent (0-100%) in relation to
adjusted welding current. Pulse current is set by
using the key pad normally used for setting of
Pulse time
Time for pulse current is adjusted between 0.003 and
2 sec.
Base amp time
Time for base amp is adjusted between 0.003 and
2 sec.
Slope-down
When welding is stopped by activation of the trigger
the machine enters into slope-down. During this
period the current is decreased linearly to the
