Reason Remedy
Arc length is growing
Particle of spatter becomes bigger
Bead width is widening
The length and height of weld penetration become
smaller.
Arc voltage is too high
Wire sticks to the base metal and too many spatters.
Bead width becomes narrow.
The depth and height of weld penetration becomes
bigger.
Arc voltage is too low
Particle of spatter becomes smaller
Bead width is widening
The depth of weld penetration becomes bigger.
Welding current is too high
Bead width becomes narrow.
The length and height of weld penetration become
smaller.
Welding speed is fast.
Particle of spatter becomes smaller
the number of spatter decreases.
The depth and height of weld penetration becomes
bigger.
Current density of wire is
high.
