5.0 GENERAL DESCRIPTION
THE PROCESS
Stud welding is a time saving tool which semi-automatically
arc welds the FULL CROSS-SECTION of a weld stud to the
base material in a fraction of a second and develops superior
strength over normal arc welding procedures.
THE UNIT
The ARC-656 is a compact , lightweight stud welding power
supply capable of welding studs through 1/2” diameter re-
duced weld base. The power supply which operates on three
phase power produces a smooth, stable welding arc. The
front panel digital display indicates the weld time which is
adjustable from .005 to 1.000 seconds. The weld current
which is not adjustable and is 650 amps only when using the
standard cable set which is supplied the welder.
6.0 ELECTRICAL INPUT REQUIREMENT
This welding power source is designed to be operated from
230v, 460v, or 575v three-phase, 60 Hertz, AC power Con-
sult the local electric utility if there is any question about the
type of electrical system available at the installation site or
how proper connections to the welding power source are to
PAGE 2
The power unit should be operated from a separately fused or
circuit breaker protected circuit.
Install three primary leads plus one ground wire (see FIG. 1)
for proper wire and fuse sizes) through the inlet hole in the
rear of the unit.
The primary cables connect to terminals labeled L or LINE.
A FOURTH LEAD (GROUND CONNECTION) SHOULD
BE FASTENED TO THE BOLT LABELED GND. (see
FIG 2 ON NEXT PAGE) The other end of the ground lead
or cable should be attached to a suitable ground such as a
water pipe, ground rod, etc. Use whatever grounding means
is acceptable to the local electrical inspection authorities.
