Welding parame-
ters in AC setup
"Minimum" and "maximum" are used for setting ranges that differ according to power
source, wire-feed unit, welding program, etc.
Effect of the AC parameters on the waveshape
(1) Balance
(2) AC frequency
(3) AC current offset
*) Factory setting: 20% shift to the ne-
gative
AC frequency
Unit Hz
Setting range Syn / 40 - 250
Factory setting 60
Syn for mains synchronisation of two power sources for simultaneous
AC welding.
IMPORTANT! If using the "Syn" setting, remember to check the "Phase sync." parameter
in AC setup 2nd.
Low frequency soft, distant arc with shallow heat input
High frequency focused arc with deep heat input
AC current offset

Setting range -70 to +70
Factory setting 0
+70 distant arc with shallow heat input
-70 narrow arc, deep heat input, faster welding speed
