WAVEFORM CONTROL TECHNOLOGY
AC/DC Submerged Arc Welding
Improves Productivity, Quality and Safety
For over 50 years, Lincoln
Electric has offered its
Submerged Arc Welding (SAW)
customers high deposition rates,
reliable penetration, and smooth
bead appearance.
Now, Lincoln brings you the first
advance in SAW technology that
provides the option of variable
polarity. Changes in the balance
of positive and negative polarity
of the AC waveform enable the
operator to change penetration
and

® WAVEFORM CONTROL TECHNOLOGY PROCESS 3/6 AC/DC Submerged Arc Welding Using AC/DC The AC/DC SAW process is the ideal choice for high-deposition, high-speed welds that can be made in the 1G position. Whether your applications demands a single arc or up to five synchronized arcs, AC/DC SAW with the Power Wave will increase weld speeds and yield higher quality welds. In multiple arc welding, as many as 5 arcs operate in a single weld puddle. The positive and negative polarity phases of the AC wave
