OPERATION

PULSE PROGRAMS:

Range (IPM*)
65 - 1200
The V350 pulse programs are non-synergic and allow independent
55 - 800 control of the wire feed speed (at the wire feeder) and the arc
50 - 700
length. The Output Control Knob on the V350, adjusts an "SPD"
75 - 550
value. Similar to trim, the "SPD" value indicates the relative arc
50 - 650 length setting. The "SPD" value displayed on the V350 may not
50 - 500
match the actual wire feed speed! The value of "SPD" is meant
85 - 770 to be a point at which to set the arc length relative to the wire feed
110 - 770
speed and should be set the same as actual speed for a starting
65 - 770
point. Depending on the application, the "SPD" value can be adjust-
75 - 770 ed to obtain the desired arc length. Refer to the detailed explana-
50 - 600
tion at the end of this section.
50 - 600
100 - 700
The operation of the Arc Control knob on the V350 is similar to the
115 - 740
PowerWave series. As Arc Control is increased, the frequency is
80 - 550 increased and the background reduced. Decreasing Arc Control will
85 - 700
reduce frequency and increase background current. Arc Control
75 - 325 acts to fine tune the arc plasma to the specific application.
75 - 450
Preferred gas selections:
Steel Argon Blends = Argon with CO2 additions from 2 to 20
% or Oxygen additions from 2 to 5%.
Stainless Stainless Argon Blends = Argon Blends =
Stainless He Ar CO2 = ~ 90% Helium, 7 1/2 % Argon 2 1/2 CO2
Aluminum 100% Argon
80 - 700
The Nickel Alloy pulse programs are non adaptive. The operator
75 - 550 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%.

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. Refer to the detailed explanation at the
end of this section.
