IMPORTANT NOTE
The Series 1 “‘DS" Head has a different feed roll and busbar assembly than the
Series 2 “‘DS’’ Head. In every other respect both heads are alike. Consequently this
booklet may be used with the Series 1 Head.
The purpose ofthis booklet is to present the information needed to set up, operate,
and maintain the LINDE “‘DS’’ Welding Head in the proper manner. It is not concerned
with welding techniques or procedures. These are covered in other Linde Instruction
Booklets.
In submerged-arc welding, the greatest degree of process flexibility and versatility
can be attained only through proper selection and use of the many items of available
equipment. For your convenience, this booklet describes much of the accessory equip-
ment as well as the Welding Heads, and explains in detail the steps to be followed in
assembling the various components. Some of the instructions may not be pertinent to a
particular installation, but we have purposely made this booklet all-inclusive to cover
as many types as possible.
PRECAUTIONS AND SAFE PRACTICES
These instructions are for experienced operators who know the general principles and the
safety precautions to be observed in operating electric welding apparatus. If you are not
certain you understand these principles fully, we urge you to read Linde’s booklet ‘Pre-
cautions and Safe Practices for Electric Welding and Cutting’ (F-52-529) which is availa-
ble from any Linde sales office, or any Linde distributor, at no charge. Do not attempt to
install or operate this equipment until you have read and fully understand these instruc-
tions.
Lbis apparatus conforms to C.S.A. Standards and is shown in the approved list of electrical equipment.

|. Introduction
A. The Welding Head
The LINDE Type "DS" welding head is designed to
feed welding wire into the welding zone at controlled
rates. Welding heads are available which will provide
any one of three output shaft speeds (see Paragraph
C).
The DS welding headas shippedto the customer, con-
sists essentially of four subassemblies (Figure 1).
These are: (1) the wire feed motor, (2) the gear re-
duction assembly, (3) the pressure rollassembly, and
(4) the busbar assembly. These four components come
assembledas a complete unit ready for mounting and
function as follows:
The wire feed motor drives the gear reducer assem-
bly (a trainof step-downworm and gear units), which
connects directly to adrive shafton whichis mounted
a vee-grooved friction feed roll. It is this feed roll
that actually feeds the welding wire to the workpiece.
The frictionnecessary for positive, non-skid feed is
provided by the pressure roll assembly, An idler
wheel in this assembly forces the welding wire into
the vee of the feed roll. This gives sufficient wedging
action to prevent any possibility of slippage under
normaloperating conditions, The copper busbar as-
sembly receives the high amperage welding current
and transmits it, through a contact nozzle, to the
welding wire.
B. Applications
The welding head is designed for either stationary
or portable mounting. Instationary installations, the
head is usually mounted in a fixed position and the
workpiece moves beneath it. Linde does not make or
sell stationary mountings, or the jigs necessary for
supporting and moving the workpiece. However,
standard equipment is available from several sup-
pliers.
For portable installations, the head may be mounted
on any of the standard LINDE machine carriages.
(As shown in Figure 2, the head, together with the
other equipment necessary for submerged-arc weld-
ing, can be mounted on the CM-37 Carriage. Spec-
ific assembly instructions are given in Section II of
this booklet. Rubber drive wheels are available for
installations on the CM-37 Carriage. These provide
improved traction when operating directly on the sur-
face of plate and sheet material.
The head may also be mounted on the LINDE OM-48
Side-Beam Carriage shown in Figure 3. This in-
stallation is designed primarily for work where the
carriage track is permanently mounted on a beam,
wall brackets, or floor posts.

In addition to the types of installation cited above, the
DS welding head also forms an integral part of other
welding machines suchas the UWM-2 Flexible Welder.
C. Operating Features
The DS welding head is used with welding currents
ranging upto 1200 amperes, a.c. or d.c. The amount
of welding current requiredfor any welding operation
is determined primarily by the thickness of the ma-
terial being welded, but will seldom, if ever, be less
than 200 amperes.
The closed loop curves shown in Fig. 4 are provided
to give an indication of the welding current and voit-

age ranges which may be obtained with the various
DS welding heads. Note that Grade 20, 20x 200
welding composition, 1/4, 3/16, or 1/8-inch diameter
Linde 36 wire and 15 ipm travel speed were used in
all cases, Since other sizes and grades of wire or
welding composition will produce additional families
of curves, this datais furnished only to show the gen-
eral operating characteristics of the DS heads.
The head wire feed motor is a 3/8 horsepower, 32-
volt, universalmotor. The motor field and armature
are connected in series. The direction of motor ro-
tation is changed by reversing the motor field con-
nections. Thisis accomplished by a reversing switch
conveniently located on the operating controls used
in conjunction with the head.
Welding wire ranging from 3/32 to 3/16 inches in
diameter can be accommodated with the DS head.
Joints of any practical thickness can Бе welded using
a multipasstechnique. In addition, buildup and hard-
surfacing operations can be done on flat, cylindrical,
and irregular shaped surfaces, using solid or tubular
welding wire.
The DS head is sold with single (12 rpm), double
(24 rpm), or triple (36 rpm) speed gearing. The dif-
ferent ratios are made available to provide the max-
imum possible efficiency withina given welding cur-
rent range.
lt is possible to convert from one speedto another by
replacing the gear reduction assembly, as shown in
Section IV of this booklet.
The welding current and wire sizes generally used
for a specific installation will determine the most
suitable wire feed speed. The relationship between
wire diameter, welding current, and wire feed speed
is shown in the table below.

The values cited in this table are based on a welding voltage of 32 volts.
These values do not apply at other voltages. At 25 valts the maximum
currents will be about 25% below those listed. Minimum currents are
approximately one half of maximum currents. No load speeds are shown,
IMPORTANT NOTE: The gearing in a reduction is
stamped on the flange. If the customer changes the
gearing, he should re-mark the head for purposes of
gear identification. Tocheck no load speed, see Sec-

Il. Installation
A. Welding Head Mounting
Procedure
The welding head is seldom mounted by itself; it is
generally used in conjunction with the Vertical Ad-
justment Assembly shown in Fig. 5. This provides
for adjustmentof the welding head without the neces-
sity of moving or adjusting other components of the
installation,
If desired, however, the head may be supported alone
by the bracketon the gear housing. The DS head may
be mounted on a 1-in. diameter steel bar or similar
device. The clamp screw on the mounting bracket
(Figure 6) must then be tightened to hold the head in
a fixed position.
Except in special cases, however, it is always recom-
mended that the head be mounted on the Adjustment
Assembly. The Horizontal and Vertical Adjustment
Assembly (Part No, 18V37) is shipped with four spacer
plates (Part No. 41W25) and four screws. These
Spacer plates and mounting hardware are used to
align the wire guide (Part No. 18V15). When the Ad-
justment Assembly is used in conjunction with the DS
head, one spacer plate is inserted between the wire
guide and the Assembly body using a set of screws
for mounting hardware. To mount the head to the
adjustment assembly:
a. Remove the shoulderbolt from the pair of mount-
ing lugs on the vertical slide of the adjustment
assembly.
b, With the insulating bushing in the gear housing
support bracket of the DS head, fit the bracket
between the mounting lugs.
c, To mountthe DS head, insert aninsulating washer
between the supporting bracket and each mounting
lug. These washers will be found in a cloth bag
tied to the Adjustment Assembly.
d. Replace the shoulder bolt through the mounting
lugs and supporting bracket and tighten the nut.

mounting,
l. STATIONARY MOUNTING
The simplest method for stationary mounting is
to bolt the horizontal and vertical adjustment as-
sembly directly to a specially prepared mounting
plate. Dimensions for use in preparing a mount-
ing device to receive the Adjustment Assembly are
shown in Figure 8.
The horizontal and vertical adjustment assembly
may also be bolted to Rack and Hinge Assembly
25V52 (see Figure 8). The Rack and Hinge As-
sembly in turn may be bolted to any stationary
vertical surface.

3. Slip the feed roll, insulating washer, and steel
washer on the feed roll shaft, in the order shown
- in Figure 12, Tighten the locknut on the end of
the roil shaft.
4. Now adjust the Pressure Roll to proper operating
position by means of the Shoulder Bolt -- (see
Figure 28). The center of the pressure roll should
be slightly below the center of the feed roll. This
positioning will exerta straightening effect on the
welding wire before itenters the nozzle assembly.
Should the feed roll slip when maximum pressure
is exerted by the pressure roll, relocate the center
of the pressure roll nearer the center of the feed
roll.
C. Contact Jaws and Contact
Nozzles
The welding current canbe transferred from the bus-
bar assembly to the welding wire either by a pair of
contact jaws, or by a contact nozzle assembly. The
nozzle assembly is used in the non-positioned fillet
welding of sheet metal and where the wire must be
conducted toa joint at some distance from the busbar.
The curved nozzle permits "trailing" the wire along
the joint--a more favorable conditionfor sheet metal
welding.
l. CONTACT NOZZLES
Either a straight or curved nozzle assembly may
be used. Details of these nozzles are givenin Fig-
ure 51, The curved type is used mainly for sheet
metal work and for making fillet welds. The wire
guide, supplied separately, connects the nozzle
assembly to the busbar,

. CONTACT JAWS
An assembly (29V54) is available which permits
the use of contact jaws with the DS head. It is
used.in conjunction with an adaptor 22N36, and an
insulator sleeve 41W89. The adaptor adapts the
7/8 inch-14 thread of the jaw holder to the 5/8
inch-1i thread of the standard wire puide 41W65
or 41W70,
Order, in addition to the holder, the appropriate
jaws. These jaws are available in four sizes to
fit welding wire from 1/8to1/4inches in diameter.
They are not supplied with the welding head, since
only one or two sizes are normally required by
one user.
Contact jaws areused inpairs. Wire grooves are
machined on both sides of each jaw. When one
groove is worn too deep for further use, the jaw
can be reversed end-for-end to use the groove on
the opposite side.
The following table shows the proper jaws to order
for each size welding wire:

Mounting the Small Wire Reel
Five special brackets are available for mount -
ing the small wire reel (Part No. 19V89), One
is for use with the CM-37 Machine Carriage.
Another is available for use on the LINDE
OM-48 Side-Beam Carriage, A third is for
use on the LINDE WM-6 Contour Welding
Machine. Twoadditional brackets are avail-
able for mounting two wire reels on a CM-37
or OM-48 carriage for multiple electrode
welding applications.
To mount on the CM-37 Carriage, first re-
move one of the locking screws from the
swivelassemblyas shown in Figure 17. Screw
the bracket to the swivel assembly with the
four socket-head screws supplied with the
bracket. Mount the wire reel flange on the
bracket using the screws supplied with the
reel. In Figure 17, the flange is shown in
position.
On the OM -48 Carriage, the flange of the wire
reel is screwed directly to the bracket which
supports both the reel and the hopper,
For mounting on the WM-6 Contour Welding
Carriage, a special mounting bracket is re~
quired. This is supplied on order with the
carriage. Thebracket isscrewed directly to
the reelflange and the bracket and reel as-
sembly is bolted directly to the vertical
mounting plate.
Mounting the Large Wire Reel
For mounting on the OM-48 Side-Beam Car-
riage, the 38V22 reel (shown in Figure 18)
mounts on a plate which is in turn bolted to
the top of the carriage. A heavy bushing in-
sulates the 38V22 reel so the base does not
have to be insulated.
For stationary mounting, the 07V69 reel is
generally used. If used with high-frequency,
the base must be insulated from the support.

Mounting the OM-48 Hopper Assembly
The OM-48 Hopper Assembly (Part No. 19/98) is
mounted on the OM-48 Wire Reel Bracket as shown
in Figure 3. Mounting hardware is supplied with
the hopper assembly. This Hopper does not have
a valve. (Delivery of composition to welding zone
is ordinarily controlled by use of a composition
gate, but may be controlled by use of a strong
spring wire clip on the rubber hose.)
. GATES FOR WELDING COMPOSITION (FIGURE -
21)
LINDE Automatic and Manual Welding Composition
Gates provide a simple and convenient means for
controlling the flow of welding composition to the
welding zone. The amount of welding composition
deposited per unit of weld length is regulated by
merely raising or lowering the entire gate as-
sembly and by cutting the end of. the tube with a
hacksaw or file.
To installa gate, remove the hose from the mount-
ing hole in the Tube and Pointer Assembly or
Nozzle Guide Whee! Assembly. (See Figs. 20 and
23). Slide the receiving tube of the Gate up into
this mounting hole. Adjust to the desired height
above the workpiece, and tighten the setscrew.

. THE VOLTAGE CONTROL
The function of the voltage control is to maintain
the welding voltage at a constant, predetermined
value during welding operations by governing the
speed of the wire feed motor. Information on the
control will be found in the instruction booklet
covering the control.
GUIDING DEVICES

raises the carriage idler wheels off the ground
entirely; the resultant three-point suspension
makes for easy, accurately controllable man-
ual steering.
As illustrated, the guide wheel mounting
bracket is screwed directly to the handle
brackets on the carriage with the socket head
screws supplied. The steering handle screws
directly into the shank of the wheel fork.
(b}) Nozzle Guide Wheel: This guide wheel is de-
signed primarily for non-positioned fillet
welding. It is mounted ahead of the nozzle
assembly, and automatically guides the weld-
ing head along the vee of the joint. The noz-
zle guide wheel raises the carriage idler
wheels and steers the carriage along the joint.
The guide wheel is mounted by removing the
Welding Composition Tube and Pointer As-
sembly, and installing the guide wheel assem -
bly in its place, in the position indicated in
Figure 23. Slidethe rear clamp on the guide
up the contact nozzle until the bottom of the
guide wheel is about 1 inchbelow the end of the

to hold the assembly in place, and insert the
rubber hose through the center clamp,
This guide wheel assembly may also be used
in conjunction with a Welding Composition
Gate. Remove the rubber hose from the cen-
ter clamp, and insert the receiving tube of
the Gate.

||. Operation
A. Precautionary Information
Asinall electric welding apparatus, there are cer-
tain parts ofthe equipment exposed to contact by the
operator which are "live" and at the welding voltage
potential, The parts are never at a higher potential
than the open-circuit welding voltage. This does not
exceed the ordinary house lighting voltage of 110 volts
which generally is not considered dangerous.
Under some circumstances, however, low voltages
can cause serious injury when the resistance of the
electrical path throughthe human body is low. Such,
for example, isthe case when the skin of a person is
wet, from perspiration or otherwise, and when the
body of such person is in contact with the ground or
a grounded steel plate. Inaddition, a shock can lead
to other injuries caused by the uncontrolled physical
reaction which results. Every operator should be
aware of the ‘live’ parts of the machine and should
read and observe the recommended operating pro-
cedures and precautionary information.
1. Never touchthe following parts of the installation
when the welding current Contactor Switch is in
the "ON" position:
Busbar
Welding Tip
Wire Feed Roll and Pressure Roll
Welding Wire
Wire Reel
13
2. Turn off the Contactor Switch when welding opera-
tions are discontinued for any length of time. In
the DS Headinstallation, welding action is gener -
ally stopped by throwing the wire feed switch to
the "OFF" or neutralposition. This does not turn
off the open circuit voltage, and the operator can
receive a shock from touching any of the "live"
components listedpreviously. Never lift the weld-
ing machine by hand or crane with the contactor
switch "ON", When moving the machine, detach
the 8-pole plugfrom the voltage control toprevent
accidental closing of the welding contactor.
. Be sure all components of the installation are well
grounded where required, All necessary ground
connections are shown in the wiring diagrams fur-
nished with the equipment. Rough handling or
movement can cause failure of a switch or other
electrical part, and connect one side of a particular
circuit to the control or switch case. If the ap-
paratus is well grounded, however, the control or
switch will not give a shock when touched, Fuses
should not be larger than those specified in the instructions,
Care shouldbe taken to prevent accidental striking
of open arcs, Anopen welding arc gives offa bril-
liant light which, on continuous exposure, may be-
come extremely painful to the eyes.
(a) Never use the inching button control when
welding current contactor is turned on. An
arc will strike if the “live” wire accidentally
touches the work,
(b) Cover the end of the welding wire where it
contacts the workpiece with welding compo-
sition before starting to weld.
(c) Make sure the path of travel for the machine
is clear. if a ‘live "part of the machine touches
a grounded object, such as a steel building
support member, an open arc will occur.
5. Always wear goggles when chipping or removing
solidified compositionfrom the finished weld zone.
Fused particles are extremely sharp and can ser-
iously damage the eyes,
B. Wire Reel Instructions
To assure trouble-free feeding of LINDE wire from
LINDE reels, refer toFigure 47 (small wire reel) or
49 (large wire reel), and follow these instructions:
1. See that reel brake is tight enough so that reel
will not revolve easily.
2 Loosen thumbscrew or handles on each of the
retaining fingers of the reel arms.
3. Pull the fingers toward you, then turn them to
point toward the reel hub.
4. Position the thumb nuts or handles so that they
will not interfere with the placing of the coil on
the reel.
5, Remove paper wrapping from coil, but do not
cut binding ties.
6. Position the coil of wire sothat whenit is placed
on the reel, wire will draw off toward the feed
roll,
7. Place the coil on the reel, pull the reel fingers
toward you, and turn them outward. Tighten the
thumbscrew or handle just enough to keep the
coil from spreading. (Note: On the small wire
reel, each of the fingers actually consists of two
fingers off-set by 120-degrees and approximately
1-inch apart. This finger design permits quick
and easy accommodation of different coil widths
by simply rotating from one finger to the other.
The width between the fingers of the large wire
reel canbe altered with the adjusting screw. The
arms of the large reel are adjustable and can be
expanded against the inner diameter of the coil
by means of the adjusting wheel.)
8, Beginning with the tie wire or band that holds
the starting end of the coil, cut all but the last
tie. Cut off any kinked end of the coiled wire.
Hold the starting end of the coiled wire, and
drawing it toward the feed roll, cut the last tie.
Put the starting end in the feed roll, being care-
ful not to allow the coil to loosen.
9. Adjust the reel brake to provide just enough
braking to prevent expanding of the wire and
prevent coasting of the reel when wire is drawn
14
р р
FIG. 24 — Small Wire Reel
from it. Too much braking will cause the strand
that is being pulled from the coil to wedge into
the coil in those parts of the circumference where
the sides of the coil are not confined by the reel
fingers, or may cause it to wedge between the
fingers andthe coil. This may bendthe wire and
may also result in irregular restraint, and cause
irregular wire feeding by overloading the drive
motor. Too little pressure will permit the reel
to over -run causing the wire to tangle or "ground
against adjacent metal,
10. If the inner end of the coiled wire is not ade-
quately fastened to the cardboard rim it should
be secured to one of the anchors provided on the
reel.
As supplied, the small wire reel is assembled with
brake spring 28Z64 and a1/2-inch plain steel washer.
This spring and washer are used for the majority of
submerged arc applications. Where lighter braking
action is required {with small-diameter wire, for
example) replace with spring 82W12 and guide washer
18N26. These are supplied in a cloth bag tied to the
reel.

FIG. 25 — Large Wire Reel
As supplied, the fingers on the small wire reel are
assembled on the reel with their pins in position #1
for use with standard coils 3, 3-1/4, and 4-inches
wide, as well as out-of-tolerance coil widths up to
4-5/8-inches. If coils 2 inches wide are to be used,
remove the pin from position #1 and install it in po-
sition #2.
The reel should be aligned with the feed roll so that
the wire does not pull against the fingers. If there
is an alignment problem, a Wire Centering Guide,
Part No, 29V73, is recommended (See Fig, 48).
C. Performance Check
Before starting to weld, make the following check to
be sure that all components of the welding setup are
in proper operating condition: (Refer to the circuit
and installation diagram in the control instruction
booklet.)
1, Check all external circuits before any power is
turned on. Be sure the welding cable leads are
clamped securely to the busbar and the workpiece.
Be sure all connecting plugs are fitted tightly in
their receptacles, and that all ground connections
make good contact.
2. Turn on the 115-volt a.c. current supply to the
voltage control.
3. Press the inching button to be sure that the inch-
ing circuit is working properly. If a feed-retract
switch is provided with the control, be sure it
is in either the feed or retract position and not
in the center neutral position,
4. Adjust the tension of the pressure roll as follows:
(a) Unscrew the pressure adjusting screw hand-
wheel to completely relieve any pressure
on the spring which engages the plastic block
of the roll assembly.
(b) Loosen the shoulder bolt (see Fig. 28) that
attaches the assembly arm to the gear hous-
ing mounting ear,
lc) Turn the assembly arm counter-clockwise
when viewed from the side opposite the shoul-
der bolt (handwheel to the left) to eliminate
15
all tolerance in this direction. This will spring
the pressure roll to the nearest position to the
feed roll.
(d) Set the assembly within the slot range of the
head mounting ear to give the required
straightening action,
(le) Tightenthe shoulder bolt and set the pressure
adjusting handwheel to apply the required
Spring tension of the roller onthe wire to give
uniform speed without slippage.
NOTE: When large wire sizes are used, set the pressure as
above with the wire engaged in the feed roll groove.
5. Feedout about 18-inches of welding wire to check
for straightness. Readjust the position of the pres-
sure roll if necessary.
6. Close the travel switch temporarily to be sure
that the carriage travel circuit is functioning.
7. If thereis a questionas to whether the proper feed
ratios as shown in the tables on page 5 are being
attained, the no-load speeds can be checked as
follows:
Remove motor plug from control and connect a
variac or other supply of 32 volts to plug pins 3
and 6, Connect a jumper across pins 4 and 5.
Place a chalk mark on the wire feed roll for ref-
erence and count the revolutions during one min-
ute. The RPM may be more, but should not be
less than the values shown on page 5. Do not use
inching button for checking speed since the motor
voltage will be less than 32 volts. In certain CM-
37 Carriage installations, it is recommended that
wire guide assembly C-346323 be used with the
DS head to guide the wire to the feed roll. The
wire guides are used in place of the slotted guide
provided on slide assembly 18V37 (see Fig, 19),
D. Operating Procedure
Refer to control instruction booklet.
IV. Disassembly and Maintenance
NOTE: Both the 115 volt supply to the voltage control and the welding transformer or
generator current supply to the welding cables must be shut off before any disassembly
or maintenance operations are undertaken,
A. Normal Maintenance Schedule
for Welding Head Installations
1, GENERAL
Little maintenance is required to keep the welding
head and its auxiliary equipment in top operating
condition. Allnecessary lubrication is done at the
factory before shipment.
It is important, however, that moving parts such
as the feed and pressure rolls, the horizontal and
vertical adjustment slides, the wire feed motor,
etc.be kept cleanand free of welding composition.
Cleaning is best accomplished by regularly biow-
ing off these parts withdry compressed air. This
should be done at least once for every eight hours
of operating time; more often if necessary.
. WIRE FEED MOTOR MAINTENANCE
Check the wire-feed motor brushes every six
months, or every 200 hours of operation. Unscrew
both brush plugs as indicated in Figure 26, and
lift out the brush and spring assemblies. It 1s
good practice to mark each brush with apencil as
it 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 motor is put back into
operation due to improper brush seating.
FIG. 26 — Removing Motor Brushes
16
Examine the brushes. Make sure that each brush
surface in contact with the motor commutator has
the bright, polished finish that indicates good con-
tact. The polished area should cover essentially
all of the contacting surface of the brush.
When replacing a brush in the motor, be sure to
put it back in the same brush holder, and in its
original position. Be sure also that the brush
rides freely in its holder. New brushes are ap-
proximately 3/4-in. long. When they have worn
down to 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
smooth, with a polished brown color where the
brushes ride it. If the surface appears rough, dis -
assemble the motor and remove the armature.
Polish the commutator surface with No, 00 sand-
paper ‘and wipe clean, For this operation, it is
preferable to rotate the armature in a lathe.
CAUTION: Never use emery cloth or emery stone for this
operation. Emery is a conductor of electricity, and any residual
loose particles may short circuit the commutator segments
during 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 in a lathe, and undercutting the mica seg-
ments.
Replacement of brushes and commutator main-
tenance should be performed only by an exper-
ienced electrician, |
. PORTABLE INSTALLATIONS
Refer to the proper instruction booklet for routine
maintenance of the machine carriage.
_ ADJUSTMENTS FOR DIFFERENT DIAMETER
WIRE
When joint design or welding conditions require
changing from one wire diameter size to another,
it is necessary to replace the V-Groove feed roll
with the one to accommodate the new wire size,
The welding tip or jaws willalso have to be changed.
In addition, it may be necessary to change both
wire guide and contact nozzle, depending upon the
diameter wire being used. Paragraphs. C and D
of Section II gives capacities of all welding tips,
wire guides, and contact nozzles. Paragraph B
of Section II lists the V-Groove feed rolls for the
various diameter wires.
B. The Welding Head
1.
DISASSEMBLY
Remove the wire guide and contact nozzle assembly
from the busbar. Remove the welding cables from
the busbar. Remove the feed roll from its drive
shaft. Remove the entire welding head assembly
from its mounting. Put all insulating washers,
bushings, etc. in a handy place where they will be
available when the head is to be remounted. The
welding head may now be disassembled in the fol-
lowing manner:
(a} Removing the Busbar: Unscrew the socket
head screws which hold the busbar to the gear
reducer housing as shown in Figure 27, Re-
move the busbar assembly and the insulating
blocks.
(b) Removing the Pressure Roll Assembly: With
a 7/8-in, open end wrench, unscrew the mount-
ing bolt as shown in Figure 28. Remove the
bolt and steel washer, and take off the pres-
sure roll assembly.
{с} Removing the Gear Reducer Assembly: With
a 3/8-in. wrench, unscrew the three hex nuts
on the inner side of the gear housing mount-
ing flange (see Figure 29). Carefully pry the
gear reducer assembly away from the wire
feed motor. Avoid damaging the paper gasket.
. REASSEMBLY
The welding head is reassembled by reversing
the procedure given above. When attaching the
gear unit to the motor assembly, make sure the
paper gasket is in place and in good condition. If
torn or otherwise damaged, replace it with a new
one. Align the spur gear teeth. Be sure the two
units fit up snugly before screwing them together.
This will indicate that the motor Shaft spur gear
is interlocked correctly with the spur gear in the
gear reducer unit,
When replacing the busbar, be sure to include all
insulationto properly insulate the busbar from the
gear housing.
. REPLACING THE PRESSURE ROLL
After long service, the pressure roll may develop
a deep groove where itcontacts the welding wire.
The roll should then be replaced with a new one,
to prevent the wire from binding or slipping during
welding operations. Replacement is done as fol-
lows:
(a) Removethe pressure roll assembly from the
welding head as explained above (Paragraph
B-1-b).
(b) Unscrew the retaining nut and washer frorn
the roll shaft. Withdraw the shaft and remove
the roll from the yoke. See Fig. 39.
(c) Check the condition of the pressure roll,
Place the roll on the shaft. If it sticks, wob-
bles, orhasa sloppyfit, it should be replaced,
FIG. 29 — Removing Motor Retaining Nuts
The roll and the bearing come as a single unit
1f the pressure roll shaft nut on older as-
semblies tends to loosen, the difficulty may
be overcome by the use of anelastic stop nut,
Part No. 96W61,
(d) Reassemble the roll, shaft, washer, and nut.
(e) Remount the assembly on the welding head,
and adjust to the proper position as explained
previously.
. WIRE FEED MOTOR DISASSEMBLY
After the gear reducer unit has been removed from
the motor assembly, as described in Paragraph
B-1-C of this section, the motor may be disas-
sembled for maintenance. NOTE: An experienced
electric motor repairman should do this work.
(a) Unscrew both brush plugs, and remove the
brush and spring assemblies (see Figure
26.) Note how each brush is withdrawn so
that it may be replaced in the same position,
Match-mark the brushes and holders.
(b) Unscrew the two motor housing screws as
shown in Figure 30.
(c) Withdraw the motor end housing.
(d) Lift out the motor armature, and remove the
shroud.
(e) To remove the motor field, unscrew the two
retaining screws as shown in Figure 31.
({) To reassemble, reverse the procedure out-
lined above, An exploded view of the motor
is shown in Figure 32.

5, DISASSEMBLY OF THE GEAR REDUCER UNIT
For repair purposes,or for changing the gear re-
duction ratio, itis recommended that the complete
Gear Reducer Assembly be ordered. This assem-
bly is complete, packed with grease, and ready for
mounting on the motor assembly.
In certaincases, however, immediate field repairs
may be required. The Gear Reducer Assembly is
disassembled in the following manner (this should
be done only by an experienced machinist):
(a) First disassemble the welding head in ac-
cordance with the instructions given in Para-
graph B-1 of this section. Remove the gear
reducer unit from the wire feed motor.
(b) Markall bearing caps A,B,C, and D as shown
in Figures 33 and 34 and remove.
(c) From the motor side of the gear housing, tap
out bearing F throughport B. Usea brass or
copper drift for this operation, to avoid dam-
age to the bearing.
(d) Lift out the worm and gear A.
(e) Press worm and gear B from port A until
bearing G is clear of the housing.
(f} Inserta yoke, witha slot about 5/8-inch wide,
between bearing G and the housing.
(g) Clamp two 3/16-inch diameter x 5-inch long
bronze wires in a vise, parallel to each other
and about 3/4-inch apart. Insert them through
the motor side of the housing, so that they
straddle worm B and bear against worm gear

one of the slides becomes jammed by accumulations
of welding composition or other foreign material.
1,
Remove the welding headfrom the adjustment as-
sembly by removing the shoulder bolt.
-_ Loosen the two clamp screws on top of the arm,
and slide the arm off the shaft.
. Remove the four socket head screws which hold
the armto the horizontal slide. Remove the hor-
isontal and vertical adjustment slides.
Tap out the pinon the horizontal adjustment shatt,
and remove the plate on the same side.
. Remove the shaft by turning it to the left.
. Remove the four cap screws and separate the ver-
tical adjustment from the horizontal adjustment

. To reassemble, reverse the procedure outlined
above.
D. Rocker Hinge and Swivel
Assembly
Ordinarily no attempt should be made to disassemble
the swivel. Ifit becomes jammed or otherwise dam -
aged, it should be replaced with a new unit, and re-
turnedtothe factory for repair. It is difficult to re-
pair this unit because it contains several ball bear-
ings which fall out of position whenit is disassembled.
V. Replacement Parts
HOW TO ORDER REPLACEMENT PARTS
1. All replacement parts are keyed on the drawings which follow. Two types of numbers are
