13.4 Aluminum MIG welding conditions table (Reference)
•
In aluminum MIG welding, poor shielding or
arc off error may occur depending on
welding conditions, such as, gas flow rate
and material of the base metal. Make sure to
specify appropriate welding conditions, that
is, set the
torch angle at welding to “angle of
advance”, adjust the
gas flow rate to
appropriate value and perform test welding
to determine appropriate conditions for the
applied material of the base metal.
