Crater "ON" (with initial condition)
Select "CRATER-FILL ON (no pulse) " or "CRATER-FILL ON (with pulse)" by the CRATER-FILL key to
light on the LED of the INITIAL CONDITION key.
•
Carry out twice the ON/OFF operation of the torch switch and carry out the welding operation. The
operation from the first ON to OFF enables the welding by the initial current, and the second ON
operation enables the welding by the crater current.
•
Even if the torch switch is switched off during welding, the signal will be self-hold. (The torch switch
should remain depressed and held during the INITIAL and CRATER phrases.)
•
When selecting "CRATER-FILL ON (no pulse)"
Regardless of the setting by the WELDING METHOD key, the machine automatically turns to the welding
with no pulse when the crater-fill process starts.
•
When selecting "CRATER-FILL ON (with pulse)"
When "DC PULSE" or "DC WAVE PULSE" is selected by the WELDING METHOD key, the machine
automatically turns to the pulse welding mode when the crater-fill process starts.
•
Welding method in the initial condition is the same with the main welding.
