OPTIONAL EQUIPMENT
K857 – REMOTE CURRENT CONTROL
The K857 consists of a control box with 8.5 m (K857-20 20m long)
of four conductor cable and a 6 pin Amphenol for easy connection
to the front of the power source.
The K857 (K857-20 20m long) will give the same control as the
current control on the machine depending on the position of the
current dial selector switch.
CAUTION
Extreme care must be observed when installing or
extending the wiring of a remote control. The
Remote Control cord can be lengthened to any
length by splicing four wires to the standard 8.5 m
cord before connecting to the R3R receptacle. Only
the green lead can and should be grounded to the
machine case.
(Use K857-20 for the 20m cable)
