OPERATION
PULSE PROGRAMS:

65 - 1200
The V350 pulse programs are non-synergic and allow independent
55 - 800
control of the wire feed speed and the arc length. The Output
50 - 700 Control Knob on the V350, adjusts an "SPD" value. Similar to trim,
75 - 550
the "SPD" value indicates the relative arc length setting. The value
50 - 650 of "SPD" is meant to be a starting point at which to set the arc
50 - 500
length relative to the wire feed speed. Depending on the applica-
85 - 770
tion, the "SPD" value can be adjusted to obtain the desired arc
110 - 770 length.
65 - 770
75 - 770 The "SPD" value displayed on the V350 may not match the
50 - 600
actual wire feed speed!
50 - 600
100 - 700 The operation of the Arc Control knob on the V350 is similar to the
115 - 740
Power Wave series. As Arc Control is increased, the frequency is
80 - 550 increased and the background reduced. Decreasing Arc Control
85 - 700
will reduce frequency and increase background current. Arc
75 - 325
Control 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 Argon Blends = Argon with Oxygen additions up to 2%.
Stainless Argon Blends = Argon with Oxygen additions up to 2%
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.
