Control Unit - Migatronic PI 200 DC HP Manuel D'instructions

Control knob
All parameters are set by the use of only
one control knob. These parameters 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 10 settings in each welding
process (MMA DC and TIG DC) = 20 program
settings.
Each program can be selected by:
1. Choose between MMA or TIG.
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
Reset of current program (Factory default settings).
Keep pressed the knob: after 3 sec the display will
start flashing to indicate the current program has been
restored to Factory settings.
The latest used program setting in the relevant
program group (MMA DC and TIG DC) will be shown
when the program key pad is selected.

Welding current
The key pad can be used to display the
welding current. Adjustable from 5A to 200A or
250A 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.
