6.6.3.4 CREATER-FILL ON (repeat)
Select "CRATER-FILL ON (repeat)" with the CRATER-FILL key.
• During welding, welding is self-held even after the torch switch is turned off. Turning on the torch switch
again switches the welding sequence to the crater treatment. During the crater treatment, the torch switch
has to be held on. Turning off the torch switch during the crater treatment recovers the welding current,
so that welding and crater (repeat) treatment are switched over repeatedly by this ON/OFF operation.
Pull up the welding torch to stop arcing.
• In this repeat operation, arc may be broken by pressing the torch switch for a long time instead of pulling
up the torch. For details, refer to "6.10
-
Setting Internal Functions".
• Welding operation by combining functions
The following types of welding operation are available by combining the crater filler and pulse slope
functions.
6.6.4 Slope setting
The selection of “Slope ON/OFF” is done with the SLOPE SELECT key in the CRATER-FILL ON,
CRATER-ON (repeat) or ARC SPOT mode. The Slope ON mode is on when the LED at the upper left of
the key is lit while the Slope OFF mode is on when the LED is not lit. In the Slope ON mode, the Up-slope
time (only in the initial current ON mode) and the Down-slope time can be selected with the
PARAMETER SELECT key. The SLOPE SELECT key is disabled in the CRATER-FILL OFF mode.
