1INTRODUCTION
This manual describes operation and use of the M2 control panel, installed in the
AristoFeed 30--4 and AristoFeed 48--4 wire feed units.
For general information on operation, see the operating instructions for the power
source.
1.1Electrode or wire?
MIG/MAG welding uses a consumable electrode, wound on a bobbin (coil).
Throughout this manual, it is referred to “wire”.
1.2The control panel
1Knob for selecting 2 / 4--stroke control mode
2Knob for setting the burn--back time
3Yellow indicating lamp -- non--specific fault indication
4Knob for setting the inductance
5Knob for setting the wire feed speed
6Knob for setting the arc voltage
1.3Remote 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.
When the remote control unit is connected, the power source is in remote control
mode; the buttons and knobs are blocked. The functions can only be adjusted via
the remote control unit.

2 -- stroke or 4--stroke
With 2--stroke, the gas pre--flow begins when the welding gun trigger switch is
pressed. The welding process begins after this. When the trigger switch is released,
welding is stopped and gas post--flow starts.
With 4--stroke, the gas pre--flow begins when the welding gun trigger switch is
pressed. When the welding gun trigger switch is released, the welding process
starts. When the trigger switch is pressed again, the welding data is reduced to a
lower value. When the gun trigger switch is released, welding is stopped and gas
post--flow starts.
Gas pre--flo w
Gas pre--flow is when the shielding gas flows before the arc is struck.
Gas post--flow
Gas post--flow is when the shielding gas continues to flow after the arc has gone out.
Burn--back time
Burn-- back time is a delay between the time when the wire starts to decelerate (i.e.
the power to the drive motor is turned off) and when the power unit extinguishes the
arc. Too short a burn --back time results in long wire stickout after conclusion of
welding, with a risk of the wire fastening in the weld pool as it solidifies. A long
burn--back time, on the other hand, shortens the stickout but increases the risk of the
arc jumping to the wire contact tip.
Inductance
Higher inductance results in a wider weld pool and less spatter. Lower inductance
produces a harsher sound but a stable, concentrated arc.
Wire feed speed
The wire feed speed is expressed in the linear speed of the wire in m/minute.
Creep start
Creep starting feeds out the wire at 50 % of the set speed until it makes electrical
contact with the workpiece.
Arc voltage
Higher arc voltage increases the arc length and produces a hotter and wider weld.

3ORDERING SPARE PARTS
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
Spare parts may be ordered through your nearest ESAB dealer, see the last page of
this publication.
The instruction manuals and the spare parts list are available on the Internet at www.esab.com
Under ”Products” and ”Welding & cutting equipment”, you will find a link to the page where you can
both search for and download instructions and spare parts lists.
