COMMENTS
The V450 pulse programs are non-synergic and allow independent
control of the wire feed speed and the arc length. The Output
Control Knob on the V450, adjusts an "SPD" value. Similar to trim,
the "SPD" value indicates the relative arc length setting. The value
of "SPD" is meant to be a starting point at which to set the arc
length relative to the wire feed speed. Depending on the applica-
tion, the "SPD" value can be adjusted to obtain the desired arc
length.
The "SPD" value displayed on the V450 may not match the
actual wire feed speed!
The operation of the Arc Control knob on the V450 is similar to the
Power Wave series. As Arc Control is increased, the frequency is
increased and the background reduced. Decreasing Arc Control will
reduce frequency and increase background current. Arc Control
acts to fine tune the arc plasma to the specific application.
Preferred gas selections:
Steel Argon Blends = Argon with CO

additions from 2 to 20
% or Oxygen additions from 2 to 5%.
Stainless Argon Blends = Argon with Oxygen additions up to 2%
Stainless Argon Blends = Argon with Oxygen additions up to 2%.
Stainless He Ar CO

= ~ 90% Helium, 7 1/2 % Argon 2 1/2 CO

Aluminum 100% Argon
The Nickel Alloy pulse programs are non adaptive. The operator
sets the output control knob to deliver the correct arc length at the
desired wire feed speed and stick out. While welding, the operator
manipulates the stick out to maintain the correct arc length. This
method of operation produces very stable arc performance consid-
ering the nature of nickel alloys.
Preferred gas: Argon/Helium Blends = for the best results add
helium to the argon base from 0-25%.

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.
