Even if the torch switch is switched off during welding, start signal will be self-hold.
The torch switch should be kept pressed during the INITIAL and CRATER period.
When turning on the torch switch again within about 2 seconds after arc
disappears, welding condition starts with CRATER condition. The condition will
continue until the torch switch is turned off. Repetition of the same operation
enables you to have crater treatment as many times as you need.
Even if welding PENETRATION CONTROL function (F13) is set to “ON”, the function
will not be carried out during the CRATER period.
