Soft-start
Pressing the trigger will initiate pre-gas. When the wire touches the workpiece a pulse boots the arc. The
machine initiates the Hot-start, upslope and then the welding process begins. When you release the trigger
the downslope will start until the Iblackout is reached. At this point a peak of current will cut the wire and
follows the post-gas. As in standard mode, you can carry on the welding during the post gas. Wait until the
end of the post gas to modify the parameters.
