Auxiliary Equipment Connection; K178-1 Mounting Platform; K162H Spindle; K163 Undercarriage - Lincoln Electric SVM 106-A Service Manual

ACCESSORIES
AUXILIARY EQUIPMENT
CONNECTION
The LN-7 GMA has the factory installed gas
solenoid valve leads attached to terminals 7
and 32A. Additional auxiliary equipment
connection is not recommended. If the gas
solenoid is NOT connected to terminals 7
and 32A, other auxiliary equipment may be
connected but the current draw must NOT
exceed 1/4 ampere.
CAUTION
Do not connect the power source contactor
to these terminals.
NOTE: The auxiliary equipment contacts
open when the trigger is released. When the
optional K418 GMA Timer Kit is installed, the
auxiliary contacts open after the postflow
time delay.
K178-1 MOUNTING
PLATFORM
This is a turntable type platform for mounting
the LN-7 GMA to the top of Idealarc power
sources. Bolt the platform to the lift bail per
the instructions (M16260) supplied with the
platform.

K162H SPINDLE

The K162H spindle is used for mounting
Readi-Reels and 2 in. I.D. spools with a 60 lb
capacity on a K303 or K376 Wire Reel
Stand. When used with Read-Reels, a Read-
Reel Adapter is required. For 8 in. O.D.
spools, a K468 Spindle Adapter is available.
The K162H is a high capacity design which
replaces the original K162 30 lb spindle. The
K162H spindle has a white spacer and has
part no. M-14587-1 molded on. The original
K162 spindle has a black spacer and the part
no. M14587. Parts may not be exchanged
from one design to the other.
WARNING
Do not use coils or spools heavier than
30 lbs on the original K162 spindle.
To mount the 2 in. spindle kit for Readi-Reels
and 10 through 60 lb spools, remove the
shaft for the standard 50-60 pound wire coils
from the mounting framework. Install the
spindle per the instructions (M15241)
shipped with the spindle kit.

K163 UNDERCARRIAGE

The undercarriage includes casters, wheels,
a handle, and related hardware. Casters are
mounted at the front and wheels at the rear
of the platform. The handle is bolted to the
front of the platform so the wire feeder can
be tilted back and wheeled like a two-wheel
truck. Installation sheet M13424 is provided
with the undercarriage.

K419 BURNBACK TIMER KIT

The kit is available for those applications
where the LN-7 GMA is used for higher
speed, fine wire feeding (0.023 in. to 0.045
in. wire sizes) where there is a tendency for
the electrode to overrun at the end of the
weld causing "sticking" in the crater. The kit
provides a precise time delay that allows the
wire to be burned off at the end of the weld.
The delay is adjustable for optimum
burnback depending on wire size, process,
procedure, etc. This kit also includes a cold
inch switch.
The K419 Burnback Kit is also useful for
those installations where the gun is clamped
in a fixture and cannot be lifted from the work
at the end of the weld.
Installation and operation
(M15060) are included with the kit.
