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.)

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 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.
