MIG 140 INVERTER WELDER 058-9305-6
Normal weld speed:
• The bead will lay smoothly over the
work piece without ragged edges
(fig p).
• The base metal puddle will be as deep as
the bead that rises above it.
• The welding operation will make a
crackling sound.
Long arc:
• The bead will be flat and wide
with
excessive spatter
(fig q) .
• The bead will undercut the work piece.
• The slag will be difficult to remove from
the edges of the weld.
Guidelines for a good weld bead
• A solid weld bead requires that the
electrode be moved slowly and steadily
along the weld seam.
• Moving the electrode rapidly or
erratically will prevent proper fusion or
create an uneven bead.
