BASIC MIG OPERATION
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.
OK
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 pene-
trating weld. Use this method when Flux Core
wire is being used. Use this method where the
unit may be reaching its maximum welding ca-
pacity. Not for use with Aluminum wire.
Correct Technique: The gun can be angled to-
ward the front of the weld when traveling for-
ward. This angle should not exceed 15 degrees.
This provides a wider and generally more pleas-
ing weld. However it is shallower penetrating.
This method typically allows a much better view
of the arc. Use for most types of welding unless
deeper penetration must be achieved.
