OPERATION
PULSE PROGRAMS:

75 - 800 The V450 pulse programs are non-synergic and allow independent
50 - 800
control of the wire feed speed and the arc length. The Output
60 - 800 Control Knob on the V450, adjusts an "SPD" value. Similar to trim,
60 - 750
the "SPD" value indicates the relative arc length setting. The value
60 - 600 of "SPD" is meant to be a starting point at which to set the arc
60 - 700
length relative to the wire feed speed. Depending on the applica-
60 - 500
tion, the "SPD" value can be adjusted to obtain the desired arc
60 - 500 length.
100 - 800
100 - 800 The "SPD" value displayed on the V450 may not match the
actual wire feed speed!
70 - 800
70 - 700
The operation of the Arc Control knob on the V450 is similar to the
50 - 700
Power Wave series. As Arc Control is increased, the frequency is
60 - 700
increased and the background reduced. Decreasing Arc Control
125 - 700
will reduce frequency and increase background current. Arc
130 - 750
Control acts to fine tune the arc plasma to the specific application.

The Nickel Alloy pulse programs are non adaptive. The operator
sets the output control knob to deliver the correct arc length at
desired wire feed speed and stick out. While welding, the operator
manipulates the stick out to maintain the correct arc length. This
60 - 700
method of operation produces very stable arc performance consid-
60 - 600
ering the nature of nickel alloys.
Preferred gas: Argon/Helium Blends = for the best results add
helium to the argon base from 0-25%.
PULSE ON PULSE
Arc Control = Pulse on Pulse frequency. For faster travel
speed welds, the arc control should be increased.
For larger puddle, slower travel speeds, the arc control
should be decreased.
