- FINAL CURRENT
○ During electrode welding the parameter makes it possible to obtain a uniform deposit of filler ma
-
terial from the start to the end of the welding process, closing the deposition crater with a current
such as to deposit a final droplet of filler material.
○ The value of this parameter can be set as a percentage of the welding current or as an absolute
value expressed in Amperes.
○ The parameter is displayed but it is not used during the welding process when the following set
-
ting is present: MULTI TACK = ON
○ By keeping the torch trigger pressed during the 3rd time, the crater filler current is maintained
thereby ensuring optimal crater filling, until the post gas time is started by releasing the torch trig

ger (4th time).
- POST GAS TIME
○ Time of post gas delivery when the welding arc is extinguished.
-
Consequences of a higher value:
•
More effective pickling (improved appearance of workpiece at the end of the welding pass).
• - Higher gas consumption.
-
Consequences of a lower value:
•
- Lower gas consumption.
•
- Oxidation of electrode tip (more difficult arc strike).
