6.16 Gas post−flow
This controls the time during which shielding gas flows after the arc is extinguished.
− Gas post−flow is set in the weld data setting menu under stop data.
6.17 Air post−flow
This controls the time during which air flows after the arc is extinguished.
− Air post−flow is set in the weld data setting menu under stop data.
6.18 Crater filling
Crater filling makes a controlled reduction in the heat and size of the weld pool
possible when completing the weld. This makes it easier to avoid pores, thermal
cracking and crater formation in the weld joint.
− Crate filling is set in the weld data setting menu under stop data.
6.19 Burnback time
Burnback time is a delay between the time when the wire starts to brake until the
time when the power source switches off the arc voltage. Too short burnback time
results in a long wire stickout after completion of welding, with a risk of the wire being
caught in the solidifying weld pool. Too long a burnback time results in a shorter
stickout, with increased risk of the arc striking back to the contact tip.
− Burnback time is set in the weld data setting menu under stop data.
