WELD:

After upslope, the power source output and the wire

feed speed continue at the weld settings.

CRATER & DOWNSLOPE:

As soon as the trigger is released, the wire feed

speed and power source output ramp to the crater

settings throughout the crater time. The time period of

ramping from the weld settings to the crater settings is

called DOWNSLOPE.

BURNBACK:

After the crater time expires, the wire feed speed is

turned OFF and the machine output continues for the

burnback time.

POSTFLOW:

Next, the machine output is turned OFF and shielding

gas continues until the post flow timer expires.

EXAMPLE 3 - 2 STEP TRIGGER:

Customized Arc

Start, Crater and Arc End. Sometimes it is advanta-

geous to set specific arc start, crater and arc ending

parameters for the ideal weld. Many times when

welding aluminum crater control is necessary to make

a good weld. This is done by setting Start, Crater

and Burnback functions to desired values. (See

Figure B.21)

For this sequence,

PREFLOW:

Shielding gas begins to flow immediately when the

gun trigger is pulled.

RUN-IN:

After preflow time expires, the power source regulates

to the start output and wire is advanced towards the

work piece at the Run-In WFS. If an arc is not estab-

lished within 1.5 seconds, the power source output

and wire feed speed skips to the weld settings.

START & UPSLOPE:

As soon as the trigger is pulled, this starts preflow.

The Strike arc established, Start time, and Upslope

parameters are used at the beginning of the weld

sequence to establish a stable arc and provide a

smooth transition to the weld settings.
