Slope process

12.4.1 Down-Slope

This gradually reduces the weld current over the time selected down to Finish Current. This allows the
operator to complete the weld without leaving a 'crater' at the end of the weld pool.

12.4.1 Post Gas Flow

This controls the period of time the shielding gas continues to flow for after the arc stops. This protects
the weld area and torch tungsten from contamination while it is still hot enough to react with
atmospheric gases.

12.4.1 Finish Current

This gives a selected small amount of current which the operator can use to neatly complete the end of
the weld.
