Pulse Frequency - Migatronic PI 200 DC HP Manual De Instrucciones

Fast pulse
Is used for selection of fast pulse.
The pulse current is equal to the
set current. It is possible to adjust:

Pulse frequency

Variable 25 - 523 Hz.
Base amp
Adjustable from 10 to 90% of the pulse current.
Synergy PLUS
The machines automatically and dynamically
adjust all overall pulse parameters during
welding, when the peak welding current has been set
by encoder.
TIG tack welding TIG-A-TACK
The machine offers one tack welding program
to allow a quick switch from welding to tack
welding. The following features will be available:
Arc ignition HF 2-times
-
No slope-up/slope-down
-
No pulse
-
Spot TIME from 0.01 to 2.5 secs in steps of
-
0.01 sec. Set the value by selecting the parameter
"spot time"
.
Electrode welding (MMA)
Is used for selection of electrode
welding. It is not possible to
change welding process during welding.
Hot start
Hot start is a function that helps to establish
the arc at the beginning of MMA welding. This
can be achieved by increasing welding current (when
the electrode is applied to the workpiece) in relation to
the set value. This increased start amp is maintained
for half a second, after which it decreases to the set
value of welding current.

start
The hot start value reflects the percentage value by
which initial current is increased, and can be set
between 0% and 100%.

Arc-power
The arc power function is used to stabilise the
arc in MMA welding. This can be acheived by
increasing welding current during the short-circuits.
The additional current ceases when the short circuit is
no longer present.

current
Arc power can be adjusted between 0 and 100% of
the welding current setting.
E.g. If the welding current is set to 40 A and arc
power to 50% the additional current is 20 A
equals 60 A when doing arc power. If the arc
power is set to 100% the additional current is
40 A equals 80 A when doing arc power.
Torch adjustment /
remote control – 7-poled plug
The regulation of welding current is made by
means of the torch potentiometer (optional). The
maximum current reachable is the level previously
adjusted on the front panel. The minimum current is
5A.
External adjustment –
8-poled plug (optional)
Can be used for foot pedal (optional) and
remote control units (optional) that use a 8-poled plug.
The function is used for arc ignition and adjustment of
the current. The maximum current reachable is the
level previously adjusted on the front panel. The actual
current is shown on the display.
Start amp can be used as a setting of minimum
current as a percentage of maximum current.
Please note: The machine will automatically start in two-times in this
function when the machine uses a software version before 1.12.
