Control Unit - Migatronic PI 400 PLASMA Betriebsanleitung

Control knob
All parameters are set by the use of only
one control
include current, pulse time, slope-up time,
etc.
This control knob is positioned in the right side of the
control panel. The digital display shows the value of
the parameter being set. The unit of measurement of
the parameter is shown on the right side of the digital
display.
A parameter can be selected by means of the relative
keypad in the relevant section. A bright indication light
indicates the parameter selected. The control knob is
then used for setting a new value.
Storage of parameters - programs
This function enables storage of programs
(often used machine settings) and shift from
one complete program to another. By pressing the
keypad the display shows a "P" and a number: "1", "2"
etc. Each number includes a program with all
parameters and functions of the machine. It is there-
fore possible to have one program for each welding
job for which the machine is used.
It is possible to store 64 settings in each welding
process (MMA, TIG and PLASMA) = 192 program
settings.
Each program can be selected by:
1. Choose between MMA, TIG or PLASMA.
2. Select program number (P01...P10). The control
knob can be used for shifting between the
programs when the key pad is kept pressed down.
The latest used program setting in the relevant
program group (MMA, TIG and PLASMA) will be
shown when the program key pad is selected.

Reset of welding programs
Select the program that needs to be reset to factory
settings. Then keep the
seconds without turning the encoder.
The program has been reset when the current
program number is flashing on and off in the display
and the -key pad can then be released again.
Welding current
The key pad can be used to display the
welding current.
Adjustable from 5A to 400A depending on the
machine model. After the welding process has
stopped, the adjusted current is shown on the display.
During welding, however, the actual welding current is
shown. During pulse welding an average welding
current is automatically shown when shifting between
welding current and base current becomes faster than
possible viewing.
Units for parameters
Units of measurement of the selected para-
meter.
Welding voltage indicator
The welding voltage indicator is illuminated for
reasons of safety and in order to show if there is
voltage at the output taps.
Overheating error indicator
The overheating indicator is illuminated if
welding is interrupted due to overheating of the
machine.
Mains error indicator
The mains error indicator is illuminated if the
mains voltage is more than 15% lower than the rated
voltage.
