CAUTION

*Failure to follow these instructions can cause immediate failure of com- ponents within the machine.

•When powering welder from a gener- ator be sure to turn off the welder first, before generator is shut down in order to prevent damage to welder.

Output Cable Connections

The output leads are connected to the output termi- nals marked “+” and “-”. They are located at the lower right and lower left corners of the front panel.

A “V” cable 12” (.30m) long to connect a K857 Remote Control (6 pin connector) with a wire-feeder (14-pin connector) and the machine (14-pin connec- tor). If a remote control is used alone the wire-feeder connection is then not used.

WARNING

ELECTRIC SHOCK can kill.

•Turn the power switch of the welding power source “OFF” before installing plugs on cables or when connecting or disconnecting plugs to weld- ing power source.

AMPTROL ADAPTER CAbLE (843)

A five wire cable, 12” (.30m ) long, used for easy connection of standard K963 Hand Amptrol or K870 Foot amptrol. The cable has a 6-pin MS-style connector which connects to the Amptrol and termi- nals which connect to 75, 76, and 77 on the machine terminal strip and to the case grounding screw. the Amptrol will control the same range of output as the current control on the welder. (if a smaller range of control is desired for finer adjustment, a K775 Remote may be used in conjunction with the Amptrol Adapter Cable Kit.) The Amptrol arc start switch is nonfunc- tional unless used with a K799 Hi-Frequency Kit.

Remote Output Control (K857 or K857-1 with K864 Adapter)

An optional “remote out control” is available. The K857 or K857-1 are the same remote control options that are used on other Lincoln power sources. The K857 or K857-1 consist of a control box with 25 feet (7.6 meters) or 100 feet (30.3 meters).

The K857 and K857-1 have a 6-pin connector and K857 require a K864 adapter cable which connects to the 14-pin connector on the case front.
