COMMENTS
The V350 pulse programs are non-synergic and allow independent
control of the wire feed speed (at the wire feeder) and the arc
length. The Output Control Knob on the V350, adjusts an "SPD"
value. Similar to trim, the "SPD" value indicates the relative arc
length setting. The "SPD" value displayed on the V350 may not
match the actual wire feed speed! The value of "SPD" is meant
to be a point at which to set the arc length relative to the wire feed
speed and should be set the same as actual speed for a starting
point. Depending on the application, the "SPD" value can be adjust-
ed to obtain the desired arc length. Refer to the detailed explana-
tion at the end of this section.
The operation of the Arc Control knob on the V350 is similar to the
PowerWave 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 CO2 additions from 2 to 20
% or Oxygen additions from 2 to 5%.
Stainless

Argon Blends =
Argon Blends =
Argon with Oxygen additions up to 2%
Argon with Oxygen additions up to 2%.
Stainless He Ar CO2 = ~ 90% Helium, 7 1/2 % Argon 2 1/2 CO2
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
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. Refer to the detailed explanation at the
end of this section.
