Set items
Set item Description Suitable application Note
NO CRATER An welding operation using
“main welding” only.
(No initial welding or crater.)
Tack welding,
Repetition of short welding,
Thin plate welding.
CRATER An welding operation using
“crater” * after “main welding”.
(No initial welding.)
Medium thick plate welding * Crater is a built-up welding that
can fill the crater part at the end of
a welding section.
INI. &CRATER An welding operation using
“initial welding” ** before “main
welding” and “crater” after
“main welding”.
** Initial welding is a welding use-
ful for stable arc start.
ARC SPOT” An welding operation that
turns off welding arc automati-
cally after a preset arc spot
time (Tspt) passed.

Note: During welding, there are certain errors of current and voltage between the value shown on

wire diameter, welding technique and extension length etc. can generate the above-mentioned
errors.
