NA-5 Automatic Welding System
Designed for Multiple Process CV Operation ... Innershield®, Submerged Arc and other Open
Arc Processes, A complete automatic control which may also be used with available procedure
and control interface options for remote operating versatility.
( Models: NA-5N, NA-5NF, NA-5S, NA-5SF >
À proven concept in automatic
welding — “set-it-and-forget-it”
automatic welding equipment.
The arc voltage and wire feed
speed can be set on digital
meters before the arc is struck
and the procedure remains
precisely set day in and day out.
NA-5N and
Travel Carriage
Six Benefits from LINCOLN® NA-5 Automatics
Solid-State Controls — Precise control of welding procedures, striking characteristics,
start and stop, bead size and shape, and arc stability facilitates
economical welding to the most exacting requirements.
High Productivity — Automatics deposit more metal at faster travel speeds than
semiautomatics to increase production, eliminate bottlenecks
and cul costs.
Low Cost Repetitive Welds — Electrode position adjustments lock tight for pushbutton produc-
tion welding with consistent quality.
Operating Versatility — Easily adjusted for a wide range of processes, feed speeds,
wire sizes, procedures and methods.
Easy Installation — Compact units with excellent flexibility fit into simple fixtures or
the most complex automated production lines.
Worry-Free Operation — Solid-state controls and rugged construction minimize down-
time and maintenance costs.
NA-5N HEAD — Includes wire feed head with straightener for cored wire (K331 A and B only)

Required Power Source:
DC Constant Voltage
Select one of the following
The Idealarc” DC-400', DC-6007, DC-655, DC-1000, or
DC-1500#! are the recommended power sources for use with
the NA-5. They are solid-state SCR controlled welders which
provide two modes of constant voltage output — one for sub-
merged arc, and one for Innershield and other open arc
processes. The DC-400, DC-600, and DC-655 are also suit-
able for stick welding.
The Idealarc CV-400* and CV-555 can be used with the
NA-5. However, the CV-400 diode option is required to utilize
the cold starting and sensing features of the NA-5 (Order
K1346-14), The CV-400 is a constant voltage DC arc welding
power source.

The standard head is equipped with cables which permit
the head to be mounted up lo four feet from the controls.
“F" models, however, do not include electrode cables.
When the head is mounted further away from the control,
extension cable assemblies must be purchased. The
K335, for the NA-55 head, includes motor, tachometer
and flux valve lead extensions with polarized plugs and
electrode cables.

The NA-5R is a versatile automatic welding system ideally
suited for remote control interlace to automated or pro-
grammable controllers and computer controlled welding
robots. (E9.40)
This new system combines the accuracy and reliability of
the NA-5 automatic control, the maneuverability of a gun
cable wire feed unit, and the process control versatility to
“communicate” with remote control equipment through
electrically isolated input and output signals.
