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.
