Problem: Gun is not being held vertical from side to
side. Wire is not being directed to the center of the
puddle. This concentrates heat on one side of the joint
and results in poor fusion on the neglected side. It
also can create more buildup on one side of the joint
than the other.
Correction: Hold the gun so that the angle of the neck
stands perpendicular from side to side.
Correct Technique: The gun is held in a near vertical
position. A variance of 5 degrees or less is acceptable
from side to side. The purpose is to prevent the arc
from being concentrated on one side of the weld joint
or the other. This balances the heat on both sides of
the joint and keeps the bead centered. Don ’ t confuse
this with push or pull angle in the travel direction.
Correct Technique: The gun is angled toward the back
of the weld when traveling forward. This angle should
not exceed 15 degrees. This provides a narrower but
more deeply penetrating weld. Use this method when
Flux Core wire is being used. Use this method where
the unit may be reaching its maximum welding capaci-
ty. Not for use with Aluminum wire.
Correct Technique: The gun can be angled toward the
front of the weld when traveling forward. This angle
should not exceed 15 degrees. This provides a wider
and generally more pleasing weld. However it is shal-
lower penetrating. This method typically allows a
much better view of the arc. Use for most types of
welding unless deeper penetration must be achieved.
