4-8. Basic Sub Arc (SAW) Welding
. Customer must supply the following: power source, power source control cable, wire drive assembly, wire drive assembly cable, drive rolls, gun,
welding wire, weld cables, remote voltage sense leads, and flux system for the desired application.
A. Basic Sub Arc (SAW) Equipment Connections
Ref. 805 007-A
! Turn off welding power
source and weld control, and
disconnect input power be-
fore making connections.
. Use remote voltage sense
leads in all applications.
. Suggested size for remote volt-
age sense wire is 12 gauge or
larger.
. For better performance for
most Sub Arc (SAW) applica-
tions, make connections to the
Submerged Arc weld output
terminal.
. Polarity: For DCEP (Reverse
Polarity), connect weld cables
and voltage sense leads as
shown. For DCEN (Straight
Polarity), reverse weld cables
and voltage sense leads.
