3 SUBMERGED ARC WELDING
Main menu -> Process
During Submerged Arc Welding (SAW), an arc melts a continuously supplied wire. The weld
pool is protected by flux.
When the SAW process is selected, you can choose between two methods by marking
METHOD using the positioning knob and pressing ENTER. Choose between AC or DC.
When the SAW process is selected, you can choose between three control methods by
marking REGULATION TYPE using the positioning knob and pressing ENTER. Choose
between constant welding current CA or constant wire feed CW or constant current CC
(CCapplies only to Aristo1000), see explanations in “CA, constant amperage”, page25,
“CW, constant wire feed”, page25 and “CC, constant current”, page25.
If Ice wire feed is selected, see “Ice wire feed”, page52, only regulation type CW can be
selected.
