OPERATION
Most pulse welding programs are synergic. As the
wire feed speed is adjusted, the Power Wave S350
®
will automatically recalculate the waveform parame-
ters to maintain similar arc properties.
The Power Wave S350 utilizes "adaptive control" to
®
compensate for changes in the electrical stick-out
while welding. (Electrical stick-out is the distance
from the contact tip to the work piece.) The Power
Wave S350 waveforms are optimized for a 0.75"
®
stick-out. The adaptive behavior supports a range of
stick-outs from 0.50 to 1.25". At very low or high wire
feed speeds, the adaptive range may be less due to
reaching physical limitations of the welding process.
UltimArc™ Control adjusts the focus or shape of the
arc. UltimArc™ Control is adjustable from -10.0 to
+10.0 with a nominal setting of 0.0. Increasing the
UltimArc™ Control increases the pulse frequency and
background current while decreasing the peak cur-
rent. This results in a tight, stiff arc used for high
speed sheet metal welding. Decreasing the
UltimArc™ Control decreases the pulse frequency
and background current while increasing the peak cur-
rent. This results in a soft arc good for out of position
welding. (See Figure B.4)
