MIG Welding
2.1
The Expression "Wire"
With MIG welding, the electrode is wound on a reel (or drum). In this manual, an
electrode of this type is referred to as wire.
2.2
Synergic Welding
Each combination of wire type, wire diameter and gas mix requires a unique
relationship between wire feed speed and voltage (arc length) to attain a stable arc.
ARISTO 2000 has a number of pre--programmed "synergic lines".
When you choose a pre--programmed synergic line corresponding to your wire type,
wire diameter and gas mix, you need only set a wire feed speed appropriate for your
welding piece. The voltage is adjusted automatically in accordance with your choice
of pre--programmed synergic line, making it much easier to quickly find correct
welding parameters.
The synergic function for welding current may be used with MIG welding. The user
sets the values for:
method
S
wire type
S
shielding gas
S
wire dimension
S
Based on these basic settings and the value specified for wire feed speed, a
microprocessor works out suitable values for the various welding technical
parameters. These parameter types are dependent on the chosen welding method
(dip/spray or pulse). For more information, see "Weld data settings" under
section 2.4.
It is possible to weld with wire and shielding gas combinations other than those
available on the controller. However, the user will have to set values for one or more
parameters.
2.3
Basic Settings
Basic settings are made from the controller's main menu.
1. Welding process = MIG
2. Welding method
For MIG welding, you can choose between two welding methods.
Dip/Spray
S
Pulse
S
3. Wire type, shielding gas, wire dimension
The following tables show the possible wire type, shielding gas and wire
dimension combinations that can be used with the synergic function for welding
current.
