Even if the torch switch is turned OFF during welding, the welding current will
be self-held. When the torch switch is turned ON again, it is switched to crater-
fill current. During crater-fill operation, the torch switch must be held turned
ON. If the torch switch is turned OFF during crater-fill operation, it is switched
back to welding current again. Those switching operation will be repeated
cyclically. It is therefore needed to perform it with the torch lifted up to turn
OFF arcing.

In addition to turning OFF arcing with the torch lifted, it is also possible to turn
OFF arcing with the torch switch held depressed for a longer time during
repetition. See Section 10.1.17, “Internal functions” for further details.
