Select "CRATER-FILL ON (no pulse) " or "CRATER-FILL ON (with pulse)" by the CRATER-FILL key to
light off the LED of the INITIAL CONDITION key.
• Carry out twice the ON/OFF operation of the torch switch and carry out the welding operation. In the
second ON operation, the welding sequence is carried out 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 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.
