CAUTION
These INSTRUCTIONS are for experienced operators. If you are not fully familiar with the principles of operation and safe practices
for arc welding equipment, we urge you to read our booklet, “Precations and Safe Practices for Arc, Cutting and Gouging, “Form
52--529. Do NOT permit untrained persons to install, operate, or maintain this equipment. Do NOT attempt to install or operate this
equipment until you have read and fully understand these instructions. If you do not fully understand these instructions, contact your
supplier for further information. Be sure to read the Safety Precautions before installing or operating this equipment.
Be sure this information reaches the operator.
You can get extra copies through your supplier.

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 wel-
ding current
4 Increase (+) or Decrease (--) selected by the
function pushbuttons. →
5 First, second and third function pushbuttons
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 unit
has been disconnected.

2 MENUS
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.

3.1 Electrode
GMA welding uses a filler wire electrode wound on a carrier such as a spool, core or
MarathonPact. This type of electrode is referred to throughout this handbook as
wire.

GMA
GMA welding melts a continuously supplied filler wire, with the weld pool being protected by shielding gas.
2--stroke
12 V
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 used) 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.

Welding Crater
filling
Gas post--flow
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.
Slow RunIn start
Slow RunIn 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 t he 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.
Vol tag e
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 inch/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.
