OPERATION

B-43

 

 

 

EXAMPLE 1 - 2 STEP TRIGGER: Simple operation The simplest trigger operation occurs with a 2 Step trigger and the Start, Crater and Burnback functions all set to OFF. (See Figure B.19)

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 welding output and wire is advanced towards the work piece at the Run-In WFS. If an arc is not established within 1.5 seconds, the wire feed speed will jump to the welding wire feed speed

WELD:

The power source output and the wire feed speed continue at the weld settings for as long as the trigger is pulled.

POSTFLOW: As soon as the trigger is released, the power source output and the wire feed speed are turned OFF. Shielding gas continues until the post flow timer expires.
