Lincoln Electric POWER WAVE R500, Руководство оператора, Страница: 24 / 56

Most pulse welding programs are synergic. As the wire feed
speed is adjusted, the POWER WAVE
® R500 will automatically
recalculate the waveform parameters to maintain similar arc
properties.
The POWER WAVE ® R500 utilizes “adaptive control” to compen-
sate 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
® R500 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 back-
ground current while increasing the peak current. This results in
a soft arc good for out of position welding. (See Figure B.4)
