PROBABLE CAUSE.
Aluminium is being welded with a drawing
problem, which causes incorrect arc ignition as
the wire is slowed down on knocking against
the piece.
The wire length at onset of welding process is
too long.
POSSIBLE SOLUTION.
Examine the drawing process. Prevent the gun from making
"knots", keeping it in a straight line. The wire must not be
slowed down when it knocks against the piece
Correct arc end operation. Do not strike too long a final
wire length.
