Shape of arc in SYNERGIC PULSED MIG:
In SYNERGIC PULSMIG the control for welding dynamics has an infl uence on shape
of pulsed MIG arc.
-9...-1
Wider pulsed MIG arc. Object: e.g. welding of square butt preparation
0
Recommendable basic setting
1...9
More narrow and better directed arc. Object: e.g. fi llet weld seams of thin basic
materials
Control of MMA dynamics
With control of MMA dynamics you can infl uence on arc in different situations.
When you make the arc harder, blow and at the same time spatter is increased.
-9...-1
Softer arc. Object: Minimizing spatter in welding at upper end of recommen
ded currents for electrode.
0
Factory setup. Normal setting for all electrode types.
1...9
Harder arc. Object: e.g. cellulose covered electrodes (9) and thin stainless
electrodes in welding at lower end of recommended currents for electrode.
Shielding gas fl ow regulation
Shielding gas fl ow can be regulated with a fl ow regulator 5....25 l/min. The display is
calibrated for Ar CO2 mixed gas (75% Ar, 25% CO2). With other gases the meter error
tolerance remains within ±10% compared with real fl ow. This is reached only when the
angle of defl ection is smaller than 15° in regard to vertical. Regulate the meter always
having the unit is in vertical position. Gas fl ow is shown in the centre of swimmer.
