CAbLE CONNECTIONS

There are two circulars connector in the wire drive compart-
ment. (See 4-pin and 12-pin---Figure A.2---Table A.1)

CAbLE INDuCTANCE AND ITS
EFFECTS ON WELDING
Whenever possible always weld in a direction
away from the work (ground) connection.
Excessive cable inductance will cause the welding
performance to degrade. There are several factors
that contribute to the overall inductance of the cabling
system including cable size, and loop area. The loop
area is defined by the separation distance between
the electrode and work cables, and the overall welding
loop length. The welding loop length is defined as the
total of length of the electrode cable (A) + work cable
(B) + work path (C) (see Figure A.3).

To minimize inductance always use the appropriate
size cables, and whenever possible, run the electrode
and work cables in close proximity to one another to
minimize the loop area. Since the most significant fac-
tor in cable inductance is the welding loop length,
avoid excessive lengths and do not coil excess cable.
For long work piece lengths, a sliding ground should
be considered to keep the total welding loop length as
short as possible.
For additional Safety information regarding the
electrode and work cable set-up, See the standard
"SAFETY INFORMATION" located in the front of
this Instruction Manual.
