OPERATION
PULSE PROGRAMS:
IMP*
65 - 1200 The EX350i pulse programs are non-synergic and allow indepen-
55 - 800 dent control of the wire feed speed and the arc length. The Output
50 - 700 Control Knob on the EX350i, adjusts an "SPD" value. Similar to
75 - 550 trim, the "SPD" value indicates the relative arc length setting. The
50 - 650 value of "SPD" is meant to be a starting point at which to set the
50 - 500 arc length relative to the wire feed speed. Depending on the appli-
85 - 770 cation, the "SPD" value can be adjusted to obtain the desired arc
110 - 770 length.
65 - 770
75 - 770 The "SPD" value displayed on the EX350i may not match the
50 - 600 actual wire feed speed!
50 - 600
100 - 700 The operation of the Arc Control knob on the EX350i is similar to
115 - 740 the Power Wave series. As Arc Control is increased, the frequency
80 - 550 is 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.
