REMOTE OUTPUT CONTROL
(K857 WITH K864 ADAPTER OR K775 )
The K857 has a 6-pin MS-style connector.
The K857
requires a K864 adapter cable which connects to the 14-pin
connector on the machine.
An optional “remote output control” is available. This is the
same remote control that is used on the Lincoln R3R, and
DC-600 power sources (K775). The K775 consists of a
control box with 8.5m of four conductor cable. This
connects to terminals 75, 76, and 77 on the terminal strip
and the case grounding screw so marked with the symbol
on the machine. These terminals are located behind the
control panel on the front of the power source. This control
will give the same control as the output control on the
machine.
REMOTE CONTROL ADAPTER CABLE (K864)
A “V” cable 300mm long to connect a K857 Remote
Control, K963 Hand Amptrol or K870 Foot Amptrol (6-pin
connector) with a wire-feeder (14-pin connector) and the
machine (14-pin connector). If a remote control or amptrol
is used alone the wire feeder connection is then not used.
AMPTROL™ADAPTER CABLE (K843)
A five wire cable, 300mm 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 terminals 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 nonfunctional unless used
with a K799 or K930-2 Hi-Frequency Kit.
See Amptrol Adapter Installation Instructions on next page.
K930-2 TIG Module
Kit supplies the high frequency plus shielding gas valve for
DC GTAW (TIG) welding applications. High frequency
bypass is built in and the DC-400 is shipped with the proper
R.F. bypass circuitry installed to protect the control circuit
while welding with a Hi-Frequency unit. A control cable
K936-1 is required, as is a Remote Control. Use either:
(a) Foot Amptrol K870, or
(b) Hand Amptrol K963-1 (for LA-9, LA-17 and LW-20
Torches), or K963-2 (for LA-26 and LW-18 Torches), or
(c) Arc Start Switch K814.
The K844-1 Water Valve Option Kit can be used with K930-
2 when TIG welding with water cooled torches. See Hi-
Frequency Kit Installation information.
K939-1 Docking Kit
For mounting the K930-2 TIG module on top of the DC-400.
K936-1 Control Cable
Control Cable for connecting the K930-2 TIG Module to a
DC-400 (9 pin to 14 pin connectors).
K870 Foot Amptrol
Remote Output Control for DC-400.
K963-1 Hand Amptrol
Remote Output Control for DC-400 (for LA-9, LA-17 and
LW-20 Torches).
K963-2 Hand Amptrol
Remote Output Control for DC-400 (for LA-26 and LW-18
Torches).
K814 Arc Start Kit
Required if TIG Module is to be used without an Amptrol.
Has 6-pin connector.
