10. OPERATION (continued)
10.1.3 Setting of the CRATER-FILL Functions
Crater is a depression left at the
termination of the weld. As it may cause
cracks and poor welding, a crater
treatment called crater-filler is used to fill in
the depression.
NOTE: When “DC” welding method is selected, you can not set to ON(-).
When treating a crater, set to “ON(-)” or “ON( )”.
In the event that crater fill is carried out, set the CRATER-FILL key to "ON(-)" or "ON( ) " .
Each press of the CRATER-FILL key [7] changes the crater-fill mode in order.
"OFF" o "ON (-)" o "ON ( )" o "SPOT"
