1 INTRODUCTION
This manual describes use of the MA4 control panel, which is installed in the
AristoFeed 30-- 4 and AristoFeed 48--4 wire feed units.
For general information on operation, see the wire feed unit and power source
operating instructions.
1.1 Control panel
1 Display
2 Knob for setting the voltage
3 Knob for setting the wire feed speed and
welding current
4 Increase (+) or Decrease (--) selected by
the function pushbuttons. →
5 First, second and third function pushbut-

1.2 Remote control unit
Using a remote control unit, the primary parameters of the welding process can be
controlled from a device other than the control panel.
Aristo machines with intergral control panels should have program version 1.21 or
higher, in order for the remote control to function correctly.
Control panel’s behaviour on connection of the remote control unit
S The display freezes in the menu showing when the remote control is connected.
Measurement and setting values are updated, but only shown in those menus in
which the values can be displayed.
S If a fault code symbol is displayed, it cannot be removed until the remote control
has been disconnected.
2MENUS
The control panel uses several different menus. They are the main, measurement
and settings menus.
2.1 Main and measurement menus
The main menu is always displayed immediately after the
machine is started. The menu shows the values which have
been set. If the main menu is displayed when welding
begins, it switches over automatically to show the measured

values (measurement menu). The measured values will be
displayed even after welding has been completed.
The settings menu can be accessed without losing the measurement values. It is only
when the knob is turned that the setting values are displayed instead of the measured
values.
2.2 Settings menu
Different values can be entered in the settings menu.
To access the settings menu, press , , or
.
When the power source is switched off and restarted, the last values to be set are
recalled.
3 MIG/MAG WELDING
3.1 Wire or electrode?
MIG/MAG welding uses a filler wire electrode wound on a carrier (bobbin or core)
This type of electrode is referred to throughout this handbook as wire.

MIG/MAG
MIG/MAG welding melts a continuously supplied filler wire, with the weld pool being
protected by shielding gas.
2--stroke
Gas pre--flow Hot
start
Functions when using 2--stroke control of the welding gun.
Welding Crater
filling
Gas post--flow
Gas pre--flow (if u sed) starts when the welding gun trigger switch is pressed (1). The
welding process then starts. When the trigger switch is released (2), crater filling
starts (if selected) and the welding current is stopped. Gas post--flow starts (if
selected).
TIP: Pressing the trigger switch again while crater filling is in progress continues
crater filling as long as the switch is held depressed (the dotted line). Crater filling
can also be interrupted by quickly pressing and releasing the trigger switch while it is
in progress.

Gas post--flow
GB
Gas pre--flow starts when the welding gun trigger switch is pressed (1): releasing
the trigger switch starts the welding process. Pressing the trigger switch again (3)
starts crater filling (if selected) and reduces the welding data to a lower value.
Releasing the trigger switch (4) stops welding entirely and starts gas post--flow (if
selected).
TIP: Crater filling stops when the trigger switch is released. Keeping it held in
instead continues crater filling (the dotted line).
Crater filling
Crater filling helps to avoid pore, thermal cracking and crater formation in the weld
when welding stops.
Inductance
Low inductance produces a harsher sound and a more stable concentrated arc.
Higher inductance gives a softer weld (less spatter) and a hotter process, allowing
the weld pool to flow out more.
Gas pre--flow
Gas pre--flow indicates the time during which shielding gas flows before the arc is
struck.
Creep start
Creep starting feeds out the wire at 50 % of the set speed until it makes electrical
contact with the workpiece.
Burnback time
Burnback time is a delay between the time when the wire starts to decelerate and
when the power unit switches off the welding current. Too short a burnback time
results in long filler wire stickout, with a risk of the wire being caught in the solidifying
weld pool. Too long a burnback time results in a shorter stickout, with increased risk
of the arc striking back to the contact tip.
Gas post--flow
Gas post--flow is the time during which the shielding gas continues to flow after the
arc has gone out.
Voltage
Higher voltage increases the arc length and produces a hotter, wider weld pool.
Irrespective of which menu is displayed, the setting value for the voltage can be
changed. The value is only displayed in the main menu.

Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
Irrespective of which menu is displayed, the setting value for the wire feed speed can
be changed. The value is only displayed in the main menu.

Explanation of the symbols
Active symbol (dark background). Active means that the function which the
symbol represents can be activated. New values can only be set when the symbol is
active.
Inactive symbol (light background). Inactive means that settings for the
function which the symbol represents cannot be changed.
From the settings menu, pressing an inactive symbol will return the machine to the
main menu.

A dot in the upper right--hand corner indicates that crater filling is ON.
