IMPORTANT
The Series 2 UWM-2 Flexible Welder has a slightly different
exterior cabinet and wire reel than the Series 3 machine. The
Series 2 model also does not contain the wire straightening guide
(see Figure 2). Both machines (Series 2 and 3) are exactly alike
in every other respect. The Series 4 machine has 4 speed gearing
instead of 3 speed gearing as in the Series 3 machine. Because
of the increased drive speed, it is possible to use 3/32 inch
diameter wire at higher currents. Consequently, 1/8 inch diameter
wire is no longer recommended for general use. A stiffener has
been added to the base plate in the Series 5 machine to increase
the rigidity of the machine. Insulation has alse been added to the
cover and base plate in the vicinity of the wire reel to prevent the
wire from short-circuiting to. the cover or base. If series number is
not shown separately, it is the first digit of the serial number.

|. INTRODUCTION
The UWM-2 Portable Flexible Welder consisting of a Wire Drive Mechanism and a Flexible At-
tachment, is a complete welding machine for connection to a suitable source of welding power. It is
especially designed for welding in positions that cannot be reached with mechanically operated weld-
ing heads. It can be used without change for welding with either alternating or direct current. The
weld is started by lightly scratching the end of the wire on the workpiece when sufficient UNIONMELT
composition has been deposited to cover the arc. The UNIONMELT UWM-2 Welder has been satis -
factorily used with welding currents up to 800 Amperes for 3/32 inch wire. (Arc voltage - 35 volts.)
The welder can be used for both production and maintenance applications. It is particularly suit-
able where a moderate amount of hand welding is done, and where continuous operation is not required.
This booklet, with two other instruction booklets, provides all the necessary information for the
installation, operation, and maintenance of the welder. The other booklets are:
A. "Instructions and Parts Data for the Series Voltage Control for the UWM-2 (Series 2) Ma-
chine,'' Form $286.
B. "Instructions and Parts Data for the UNIONMELT Flexible Welding Attachment," Form 9159,
If you donot have these booklets, you can obtain them from the LINDE district office nearest you.
li. ASSEMBLY
A. PRINCIPAL COMPONENTS
AND SEQUENCE OF OPERATION
The following paragraphs briefly explain the
functions of the parts shown in Figures 1 and 2.
The Standard Spoke-Type Wire Reel holds small
coils of wire weighing up to 75 pounds. The reel is
equipped with a brake which can be set to prevent
‘overrun,
The Welding Head Assembly, in front of the wire
reel, draws welding wire from the reel and feeds it
thr ough the flexible attachment to the welding nozzle.
The assembly consists of three main parts: A motor
and gear reduction unit provides driving power to a
feed roll. A pressure roll assembly forces the wire
down into a vee-groove on the feed roll, providing
positive traction and feeding. A busbar introduces
welding current to the flexible cable.
The Flexible Attachment Assembly (Required
Accessory) carries the welding wire from the head
to the weld zone. The assembly includes the weld-
ing current cable and a flexible tube through which
wire is fed. It terminates in a combination hopper
and welding nozzle. The hopper holds UNIONMELT
welding composition which flows down around the
welding wire as welding progresses, The operator
controls the flow of composition by raising and low-
ering the hopper. Complete parts data ‘and opera-
tional procedures for the Flexible Attachment are
given in Form 9159,
The Voltage Control Assembly automatically
maintains the selected welding voltage. Its opera-
tion depends upon the fact that the welding voltage
varies with the gap between the welding wire and
the work, When the gap is wide, the welding volt-
age is high; when the-gap is narrow, the welding
voltage is low. The control maintains a constant
voltage by varying the speed of the wire feed motor
and consequently the rate at which wire is fed into
the weld zone. When it senses" an increase in the
welding voltage, it feeds the wire into the weld faster.
This shortensthe gap between the wire and the work,
decreasing the voltage. If the welding voltage begins
to drop, the control slows the wire feed, the melt-
off rate exceeds the feed rate, and the gap lengthens.
This resultsin raising the voltage, A more detailed
description of how the control works is given in the
instruction booklet on the voltage control Form 9286,
The Current Relay connects the motor and con-
trol across the weld zone so that they may feed wire
at a controlled rate. The relay is actuated when
welding current flows through the welding cables.
The Condenser across the contacts of the relay re-
duces the arcing at the contacts, thereby lengthening
their life.
B. ADDITIONAL EQUIPMENT REQUIRED
A complete installation for use with either aiter-
nating or direct current must include the following:
1. A Flexible Attachment-(10 or 17 Feet in length.)
2. A welding transformer of suitable capacity for
a.c, welding, or a welding generator or recti-
tifier transformer for d.c. welding.
3. Control cable for connections to the voltage con-
trol box. Typeof cable and method of connection
is included in the installation section of this book.
4. Suitable lengths of 4/0 welding cable for elec-
trode and "ground" connections.
5. Welding cable lugs.
6. Welding cable "eround" clamp.

IV. PREPARING TO WELD
A. INSTALLING WELDING WIRE ON THE REEL
1, HOW TO INSTALL A COIL OF WIRE
a) Loosen the thumbnuts on the retaining fingers
of the four wire reel arms.
b) Turn the fingers so that they point toward the
hub.
c) Remove the wrapping paper from the wire coil,
but do not remove the binding wires.
d) Use the outer end ofthe coil asthe starting end.
(The inner end of some coils is tagged ''Start
This End.’ Disregard such instructions.) Slide
the wire coil onto the reel with the starting end
in the proper feed position.
ey If the inner end of the coil is not anchored to the
core of the coil, secure it under the anchoring
setscrew on the reel.
f) Turn the reel fingers outward and tighten the
thumbscrews,
g) Secure the starting end of the coil between the
feed and pressure rolls of the wire feed mech-
anism. It may be necessary to remove one or
two of the coil binding wires, but do not remove
all of the binding wires.
h) Tighten the hub spring retaining screw to pro-
vide some friction drag for the reel. The spring
pressure should be sufficient to prevent the
wire coil fromunwinding. However, it should not
be so great as to overload the wire feed motor.
i) Remove the remaining binding wires from the
coll.
2. BRAKE SPRING SELECTION
The wire reel is assembled with brake spring
287.64 and a 1/2-inch plain steel washer. (See Figure
22.) This spring and washerare used for almost all
applications. For lighter braking action, replace the
spring and washer with spring 92W12 and guide
washer 18N26 which are supplied in a cloth bag tied
to the reel. If tightening the brake screw fails to
prevent the wire from unwinding from the secured
end,a cardboardor sheet metalring may be inserted
between the reel and the coil of wire.
B. ADJUSTMENTS FOR WIRE DIAMETER
The UWM-2 Portable Flexible Welder can be
used with 3/32 and 5/64-inch wire. (The same feed
rollisusedfor all wire sizes.) However, when going
from one wire size to another, the proper tip must
be installed in the Flexible Attachment. Complete
instructions on how to change from one wire size to
another are given in Form $159 ‘‘Instructions and
Parts List for the UNIONMELT Flexible Attach-
ment.”

V. MAINTENANCE AND DISASSEMBLY
A. MAINTENANCE
Little maintenance is required tokeepthe Port-
able Flexible Welder in good operating condition. It
is important, however, that the feed’and pressure
rolls, the wire feed motor, and the flexible attach-
ment be kept clean and free of foreign material.
THE GRADUAL ACCUMULATION OF DIRT, WIRE
PARTICLES, AND "UNIONMELT" WELDING COM-
POSITION WILL EVENTUALLY CAUSE JAMMING
UNLESS THEY ARE SYSTEMATICALLY REMOVED.
FOR THIS REASON, THE WELDING HEAD PARTS
SHOULD BE CLEANED AT LEAST ONCE FOR
EVERY FIGHT HOURS OF OPERATING TIME, THE
FLEXIBLE ATTACHMENT WIRE TUBE SHOULD BE
CLEANED EACH TIME A NEWCOIL OF WIRE IS IN-
STALLED. CLEANING IS BEST ACCOMPLISHED
BY BLOWING THE PARTS WITH DRY COMPRESSED
AIR.
1. WELDING HEAD
The gear reduction housing is packed with
grease when shipped from the factory. If the
assembly is taken apart, it should be refilled
after reassembly. If the old grease has been
lost or is otherwise unusable, use ‘‘Texaco Regal
Starfak Special’’ grease. This is available from
LINDE in 5-lb. cans, under Part No. 92W10.
Check the wirefeed motor brushes every six
months, or every 200 hours of operation. Un-
screw both brush plugs as indicated in Figure 4
ini particles may short circuit the commutator
segments during the operation of the motor.
After two sets of brushes have been worn
out, check the commutator for wear. If the
surface is worn, it should be smoothed by
grinding or turning down on a lathe, and under-
cutting the mica segments.
Replacement of brushes and commutator
maintenance should be performed only by an
experienced electrician.

given in Form 9159,
B. DISASSEMBLY
1. WELDING HEAD
To disassemble the welding head, first
remove the welding cablefrom the busbar. Then
remove the feed roll assembly from the drive
shaft. Remove the entire welding head assembly
from its mounting. Put all insulating washers,

The welding head may now be disassembled in
and lift out the brush and spring assemblies, It the following manner:
is a good idea to mark each brush and holder
with a pencil as the brush is withdrawn, so that
it can be replaced in the original position. If the
position of the brushes relative to the armature
is changed, sparking is likely to occur when the
motoris put back into operation, due to improper
brush seating. (b) Removing the Pressure RollAssembly: With
a 7/8-in. open end wrench, unscrew the
mounting boltas shownin Figure 6. Remove
the bolt and steel washer, and take off the
pressure roll assembly.
(a) Removing the Busbar: Unscrew the socket-
head screws which hold the busbar to the
gear reducer housing as shown in Figure 5.
Remove the busbar assembly and the insulat-
ing blocks.
Examine the brushes. Make sure that each
brush surface in contact with the motor com-
mutator has the bright, polished finish that
indicates good contact. The polished area should
cover essentially all of the contacting surface
of the brush,

rides freely in its holder, New brushes are
approximately 3/4 in. long. When they have
been worn down tuo 1/2-in. in length, they should
be replaced with new ones,
With the brushes removed, inspect the
surface of the commutator. It should appear
clean and s:uvoth, with a polished brown color
where the brushes ride on it. If the surface
appears rough, disassemble the motor and re-
move the armature. Polish the commutator
surface with No. 00 sandpaper and wipe clean.
For this operation, it is preferable to rotate the
armature in a lathe.

drawings:
A. Standard Part Numbers. These are usually formed by two pairs of digits with a letter between (for
example: 01N21, 18V69). A few parts may have straight digit sequence (3389) or one letter followed
by several digits (A-654221). Each standard part number is accompanied by a descriptive word or
words.
B. Hardware Numbers. These are eight digit numbers (for example: 6120-3910), Hardware numbers
are usually accompanied on drawings by a one word description.
. Order standard parts by part number and part name, as shown on drawings. DO NOT ORDER BY PART
NUMBER ALONE,
. For hardware, look up number in hardware list at back of book. You will find there a full description.
"Hardware" items can usually be purchased locally. When ordering hardware from LINDE be sure to
include the complete description given in the hardware list. Donot order hardware by the number alone,
When ordering, be sure to state quantity of each part needed.
. Always state the series or serial number of the machine on which the parts are to be used, The serial
number is stamped on the unit nameplate, The ''series no." is the first digit of the serial number,
wherever the serial number starts with a digit, followed by a letter, When the serial number starts
with one or two letters, always give the complete number.
Indicate any special shipping instructions.
. Order replacement parts from the LINDE District Office nearest you.
