OPTIONAL EQUIPMENT
K857 – REMOTE CURRENT CONTROL
The K857 consists of a control box with 8.5 m (28 ft) of
four conductor cable and a 6 pin Amphenol for easy
connection to the front of the power source.
The K857 will give the same control as the current con-
trol on the machine depending on the position of the
current dial selector switch. (Current dial selector
switch not used on the R3R 375-I.)
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 28 ft
(8.5 m) cord before connecting to the R3R recep-
tacle. Only the green lead can and should be
grounded to the machine case.
K817, K817R – UNDERCARRIAGE
For easy moving of the machine, optional undercar-
riages are available with either steel or rubber tire
wheels.
K963 – HAND AMPTROL AND K870 FOOT
AMPTROL
Connect directly to the 6 pin Amphenol on the front of
the power source.
POCKET AMPTROL – (factory installed only)
The Pocket Amptrol option provides a remote current
control for the R3R welders. This “wireless” control
requires no control cable connection to the welder.
a. On the R3R 500-I and R3R 600-I the welder Current
Control (labeled “ I “ switch must be in the Remote
( ) position and the Current Dial Selector switch
in the “B” range. The R3R 375-I has only one
Current Dial Selector and no selector switch. With
the Current Control switch in the Remote position,
the current control potentiometer on the welder is
removed from the circuit and its setting has no
effect on the output. With the Current Dial Selector
switch in the “B” range position, the Pocket Amptrol
provides total control of the welder’s output.
b. Turn the welder power switch on.
c. Insert one end of the probe into the electrode hold-
er and hold the other end on the work for approxi-
mately five seconds.
