10. OPERATION (continued)
The following functions can be adjusted by F selection key [10].
*Some parameters of F (function) can be memorized for each condition No. of the feeding condition
memory function, and others apply to all feeding conditions (The parameter cannot be memorized for
each condition No.). O or X is described to the right end of each parameter item of F function to show
which is applicable to the parameter.
O: The parameter can be set for each feeding condition.
X: The parameter is common to all feeding conditions.

Selecting start current level: Function No. 1 ---- X
The factory setting of this function is [ON] that means [high] start current. If any holes are
caused at the start of welding, the [low] start current should be selected by setting the status of
Function No. 1 to [OFF].

Changing sequence in arc spot mode: Function No. 2 ---- X
It is possible to change the operation sequence so that arcing may discontinue even during arc
spot process if the torch switch is turned OFF in “ARC SPOT” mode. To change the sequence
in such way, the status of Function No. 2 should be set to [ON].
If this function status is set to [ON], the torch switch must be kept turned ON during arc spot
process.

Changing sequence in crater ON (REPEAT) mode: Function No. 3 ---- X
It is possible to change the operation sequence so that the following welding operation may be
performed by momentarily (within 0.3 sec) depressing torch switch in “crater ON (REPEAT)”
mode. With torch switch unrepressed, the level is self-held during initial current and crater
current periods as well as welding current period. To terminate the welding, depress torch
switch for longer time (not shorter than 0.3 sec). To change the sequence in such way, the
status of Function No. 3 should be set to [ON].
