SMAW
(Stick)
Arc Force
Soft (-10.0) to
Crisp (10.0)
Arc Force adjusts the short circuit current for a soft arc, or for a forceful,
driving arc. It helps to prevent sticking and shorting of organic coated
electrodes, particularity globular transfer types such as stainless and low
hydrogen. Arc Force is especially effective for root pass on pipe with
stainless electrode and helps to minimize spatter for certain electrodes and
procedure as with low hydrogen, etc.
GMAW
(MIG) and
FCAW
(Flux-
cored)
Pinch
Soft (-10.0) to
Crisp (10.0)
Pinch controls the arc characteristics when short-arc welding.
GMAW-P
(Pulsed
MIG),
Steel and
Stainless
Ultimarc
Soft (-10.0) to
Crisp (10.0)
Ultimarc regulates the focus or shape of the arc. Ultimarc values greater
than 0.0 increase the pulse frequency while decreasing the background
current, resulting in a tight, stiff arc best for high speed sheet metal welding.
Ultimarc values less than 0.0 decrease the pulse frequency while increasing
the background current, for a soft arc good for out-of-position welding.
For Pulse modes, Arc Control changes the pulsing frequency. When the
frequency changes, the Power Wave system automatically adjusts the
background current to maintain a similar heat input into the weld. Low
frequencies give more control over the puddle and high frequencies
minimize spatter.
GMAW-P
(Pulsed
MIG),
Aluminium
Arc Control
Low (-10.0)
to High (10.0)
For Pulse -On-Pulse modes, Arc controls changes the frequency
modulation. The frequency modulation controls the spacing of the ripples in
the weld. Use low values for slow travel speeds and wide welds, and high
values for fast travel speeds and narrower welds.
