OPERATION
VANTAGE
®
600 SD
Most pulse welding programs are synergic. As the wire feed speed
is adjusted, the VANTAGE
®
600 SD will automatically recalculate
the waveform parameters to maintain similar arc properties.
The VANTAGE ® 600 SD 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
VANTAGE
®
600 SD 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
current. 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
current. This results in a soft arc good for out of position welding.
