POWER FOCUS CURVES:
the curves are available in HSL series power sources in SYNERGIC
SHORT SPRAY MIG/MAG welding mode.
The difference between a standard MIG MAG and Power Focus is its concentration and pressure.
The POWER FOCUS arc concentration allows the welder to focus the high temperature of the arc in
the central section of the deposition, thus avoiding to overheat the sides of the welding. The thermally
changed area with the Power Focus arc is less widespread.
These curves differ from the other standard curves because of the acronym PF which is displayed after
the reference to the welding wire material.
Example:
SHORT/SPRAY SYN
MAT

SG2/SG3 PF
Ø:1.2
GAS: 80% Ar / 20% CO2 R4
JOB : FE55 MARIO K1
POWER ROOT CURVES: the curves are available in SYNERGIC SHORT SPRAY MIG/MAG welding
mode.
Power Root is an optimised short arc transfer with the feature of having a cold drop transfer. Power Root
allows to achieve a very high quality in root passes.
These curves differ from the other standard curves because of the acronym PR which is displayed after
the reference to the welding wire material.
Example:
SHORT/SPRAY SYN
MAT  SG2/SG3 PR
Ø:1.2
GAS: 80% Ar / 20% CO2 R4
