Fig. 4-4-2 Operating mode sequence diagram of start arc
When welding voltage and current settings are correct, but not easy to start arc, please adjust sub-menu parameter as
follow table.

P02
Wire feed speed before ignition arc
If the welding wire strikes the workpiece quickly before starting
the arc, the spatter is severe during the starting arc → reduce
the P02 value; if the arc is not open or the starting is very slow
→ increase the P02 value
P05
Initial period, default state is OFF
Arc start section in weld seam is narrow or workpiece does not
melt – increase the P05/P17 value
Arc start section in weld seam is wide or workpiece burned
through – reduce the P05/P17 value
No problem of arc start section in weld seam - OFF
P17
Initial period function time (arc start
time)
P07
Transitional time from initial period
to welding period
Formation changes a lot for arc start section in weld seam –
increase the P07 value
No problem of arc start section in weld seam - OFF
P22
Pulse current when start arc
Longer arc when start arc, work piece burns seriously, large
spatter – increase the P22/P23 value
Difficult to start arc, wire explodes, work piece and wire does not
fuse - OFF
P23
Pulse time when start arc
