“Synergic” and “ Separate ”
DC MIG, namely standard MIG/MAG, has “synergic” and “separate” modes for welding specification adjustment:
Synergic
：
There are accordant current and voltage setting for any wire type, wire diameter, protective gas. same
current have different wire feed speed, workpiece thickness, and synergic voltage; after setting current or wire feed
speed, workpiece thickness, system will have an auto match for welding voltage, which saves a separate setting on
welding voltage. User can also have arc length adjustment according to real processing requirements.
After choosing “synergic”, machine panel’s left display will show preset current( or wire feed speed, workpiece
thickness);right display will show preset voltage; wire feeder panel left display will show preset current and right
display will show preset arc length; they both can set current and voltage. Standard arc length is “0”; adjustment is
based on synergic voltage, ranging between±9.9V.
Separate: current or wire feed speed, workpiece thickness adjustment has no relation with voltage adjustment and
requires separate setting.

Parameters setting
Under standard MIG/MAG, adjustable parameters include: pre-flow time; welding specification of process: welding
current (or wire feed speed/board thickness), welding voltage, arc force (inductance); welding specification of crater
segment: welding current (or wire feed speed/board thickness), welding voltage, arc force (inductance); post-flow time.
