12.4 Finishing the Weld
In 2t Trigger Mode
1. Release the Torch Trigger Button
2. The welding currently will complete the Down-Slope process to reduce amperage from Main
Amps down to Finish Amps
3. The Post-Gas time will then complete
In 4T Trigger Mode
1. Press and Hold the Torch Trigger Button down
2. The welding current will complete the Down-Slope process to reduce amperage from Main Amps
down to Finish Amps
3. Release the Torch Trigger Button when you want the Finish Amps to stop
4. The Post-Gas time will then complete
12.4.1 Down-Slope
This gradually reduces the weld current over the time selected down to Finish Amps. This allows the
operator to complete the weld without leaving a ‘crater’ at the end of the weld pool.
12.4.2 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.
12.4.3 Finish Amps
This gives a selected small amount of current which the operator can use to neatly complete the end of
the weld.
