I. INTRODUCTION

The EH-10A Digital Welding Head is designed for

automatic mechanized mig installations which use a

microprocessor controlled, digital logic operated wire

feeding system. The Welding Head is composed of

three basic assemblies; a wire feed motor - tachom-

eter assembly, a gear reduction box, and the acces-

sory support system.

Either of two welding heads (section II following) are

available for use, and wire sizes accommodated are:

Hard ........................ .030 - 1/8 inch (.8 -3.2 mm)

Soft....................... .030 - 3/32 inch (.8 - 2.4 mm)

Flux Core.............. .045 - 1/8 inch (1.2 - 3.2 mm)

WARNING: These Safety Precautions are for

your protection. They summarize precaution-

ary information from the references listed in

Additional Safety Information section. Before

performing any installation or operating procedures, be

sure to read and follow the safety precautions listed below

as well as all other manuals, material safety data sheets,

labels, etc. Failure to observe Safety Precautions can result

in injury or death.

PROTECT YOURSELF AND OTHERS

Some welding, cutting, and gouging

processes are noisy and require ear

protection. The arc, like the sun, emits

ultraviolet (UV) and other radiation and

can injure skin and eyes. Hot metal can cause burns.

Training in the proper use of the processes and equip-

ment is essential to prevent accidents. Therefore:

1. Always wear safety glasses with side shields in any work

area, even if welding helmets, face shields, and goggles

are also required.

2. Use a face shield fitted with the correct filter and cover

plates to protect your eyes, face, neck, and ears from

sparks and rays of the arc when operating or observing

operations. Warn bystanders not to watch the arc and

not to expose themselves to the rays of the electric-arc

or hot metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeve

shirt, cuffless trousers, high-topped shoes, and a weld-

ing helmet or cap for hair protection, to protect against

arc rays and hot sparks or hot metal. A flameproof apron

may also be desirable as protection against radiated

heat and sparks.

4. Hot sparks or metal can lodge in rolled up sleeves,

trouser cuffs, or pockets. Sleeves and collars should be

kept buttoned, and open pockets eliminated from the

front of clothing

5. Protect other personnel from arc rays and hot sparks

with a suitable non-flammable partition or curtains.

6. Use goggles over safety glasses when chipping slag or

grinding. Chipped slag may be hot and can fly far.

Bystanders should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS -- Heat from

flames and arcs can start fires. Hot slag

or sparks can also cause fires and ex-

plosions. Therefore:

1. Remove all combustible materials well away from the

work area or cover the materials with a protective non-

flammable covering. Combustible materials include wood,

cloth, sawdust, liquid and gas fuels, solvents, paints and

coatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks or

crevices in floors or wall openings and cause a hidden

smoldering fire or fires on the floor below. Make certain

that such openings are protected from hot sparks and

metal.“

3. Do not weld, cut or perform other hot work until the

workpiece has been completely cleaned so that there

are no substances on the workpiece which might pro-

duce flammable or toxic vapors. Do not do hot work on

closed containers. They may explode.

4. Have fire extinguishing equipment handy for instant use,

such as a garden hose, water pail, sand bucket, or

portable fire extinguisher. Be sure you are trained in its

use.

SAFETY PRECAUTIONS

10/98

5. Do not use equipment beyond its ratings. For example,

overloaded welding cable can overheat and create a fire

hazard.

6. After completing operations, inspect the work area to

make certain there are no hot sparks or hot metal which

could cause a later fire. Use fire watchers when neces-

sary.

7. For additional information, refer to NFPA Standard 51B,

"Fire Prevention in Use of Cutting and Welding Pro-

cesses", available from the National Fire Protection Asso-

ciation, Batterymarch Park, Quincy, MA 02269.

ELECTRICAL SHOCK -- Contact with live

electrical parts and ground can cause

severe injury or death. DO NOT use AC

welding current in damp areas, if move-

ment is confined, or if there is danger of

falling.

1. Be sure the power source frame (chassis) is connected

to the ground system of the input power.

2. Connect the workpiece to a good electrical ground.

3. Connect the work cable to the workpiece. A poor or

missing connection can expose you or others to a fatal

shock.

4. Use well-maintained equipment. Replace worn or dam-

aged cables.

5. Keep everything dry, including clothing, work area, cables,

torch/electrode holder, and power source.

6. Make sure that all parts of your body are insulated from

work and from ground.

7. Do not stand directly on metal or the earth while working

in tight quarters or a damp area; stand on dry boards or

an insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.

9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)

for specific grounding recommendations. Do not mis-

take the work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS —

May be dangerous. Electric current flow-

ing through any conductor causes lo-

calized Electric and Magnetic Fields

(EMF). Welding and cutting current cre-

ates EMF around welding cables and

welding machines. Therefore:

1. Welders having pacemakers should consult their physi-

cian before welding. EMF may interfere with some pace-

makers.

2. Exposure to EMF may have other health effects which are

unknown.

3. Welders should use the following procedures to minimize

exposure to EMF:

A. Route the electrode and work cables together. Secure

them with tape when possible.

B. Never coil the torch or work cable around your body.

C. Do not place your body between the torch and work

cables. Route cables on the same side of your body.

D. Connect the work cable to the workpiece as close as

possible to the area being welded.

E. Keep welding power source and cables as far away

from your body as possible.

II. REQUIRED EQUIPMENT

A. Two Roll Drive Digital Welding Head Package

This head provides wire speeds from 0 - 1000 ipm using a 40:1

gear reduction ratio, and accessory support wire drive assembly.

The motor-tachometer power and control signals are provided

through a 5-pin amphenol plug.

The complete Two Roll EH-10A Digital Welding Head Package,

will consist of the following with custom variations as listed be-

low.

D. Optional Accessories

1. Wire Straightener, P/N 34V74 (See Figure 2). By manipu-

lating the adjusting screw, various pressures can be placed

on the welding wire as it passes through the wire straight-

ener, straightening the wire and removing any kinks or

residual curvature.

To install the wire straightener, remove the inlet wire guide

(29N13) and insert (05N58) from the accessory support,

and screw it into the straightener. If wires larger than 3/32-

in. are used, the insert (05N58) should be omitted. This

assembly (straightener/inlet wire guide) is then inserted into

the clamp of the accessory support and secured by tighten-

ing the locking handle.

Either of two additional accessories are required to com-

plete the installation on the wire inlet side of the straightener:

a. Wire Inlet Guide, P/N 11N53, or --

b. Wire Wiper Holder, P/N 598763.

2. Wire Wiper. The wire wiper effectively cleans and lubri-

cates the welding wiper as it is being fed, thus providing

smoother wire feeding and longer conduit life. A complete

wiping assembly consists of a Felt Wiper (P/N 598537, Pkg.

of 10) and one of the Wiper Holders following:

a. Wiper Holder, P/N 598763, screws into the optional wire

straightener (see D-1 and Figure 2).

b. Wiper Holder, P/N 598764, screws on to the accessory

support’s inlet wire guide as shown in Figure 4.

III. DESCRIPTION

A. The Welding Head

The EH-10A Digital Welding Head illustrated in Figure 1 is the

wire drive mechanism which, when used in combination with

appropriate accessory and control equipment, feeds welding

wire to the weld zone at controlled rates. Wire speed is precisely

controlled by a microprocessor/J-governor closed loop digital

feedback circuit which constantly monitors the welding head’s

wire speed through its optical tachometer.

The force for feeding welding wire is provided by a rapid

response, permanent magnet, open-ventilated motor. The motor-

tachometer is mounted to a gear reduction unit which has a feed

roll or insulated drive gear assembly (depending on the acces-

sory support provided) mounted on its output shaft. The gear

reduction is composed of two sections of gearing which reduce

the output speed of the motor to that required for feeding wire.

The accessory support assembly provides the back-up force

necessary for positive non-slip wire feed. The Four Roll Drive

Accessory Support Assembly (P/N 600216,Figure 6) is fully

covered in booklet F-12-821. The Two Roll Drive Accessory

Support Assembly (P/N 49V51, Figure 5) is fully covered in

booklet F-15-632. Both of these assemblies utilize a quick

release clapper/pressure roll assembly which allow you to

reduce wire change and pressure resetting time without disturb-

ing the pressure spring setting. The assembly also includes

quick release turn-locking handles for mounting a torch and/or

wire conduits. This assembly comes equipped with a pressure

roll but does not include a feed roll. Refer to Table 1 page 5 to

select proper feed roll for wire size and type to be used.

C. Feed Roll and Outlet Guides

Feed rolls and outlet guides are not supplied as part of the

accessory support and must be ordered seperately. See Table

1 on page 5.

IV. INSTALLATION AND OPERATION

A. MOUNTING THE WELDING HEAD (2 Roll Drive)

All EH-10A Digital Motor-Gear Units are lubricated with grease

and must be mounted in a horizontal position (at no more than

45° from level) with the vent plug on top of the gear reduction

assembly to avoid lubricant leakage thru the vent plug.

B. INSTALLING THE FEED ROLL

To install the feed roll, proceed as follows:

1. Release the clapper on the accessory support assembly

(Figure 4) by disengaging the retainer from the clapper fork.

2. Remove thumbscrew, bell washer and flat washer from the

feed roll shaft.

3. Slip the feed roll on the shaft, engaging the key. Be sure to

observe the “THIS SIDE OUT” marking on the feed roll.

4. Replace flat washer, bellwasher and thumbscrew, tighten-

ing screw sufficiently to eliminate all end play from the feed

roll.

C. INSTALLING INLET AND OUTLET WIRE GUIDES

1. Inlet guide 29N13 and insert 05N58 are supplied with the

accessory support assembly 49V51 (see Figure 4). They

are held in place by rotating the locking handle on the

accessory support. Note that insert 05N58 should be re-

moved if 7/64-in. or 1/8-in. cored wire is to be used.

2. An outlet guide is supplied as part of the wire feed accesso-

ries kits for the torch used. The guide is first attached to the

wire feed conduit, then locked in place in the clamp at the

outlet side of the accessory support assembly.

D. INSTALLING SPOOL/COIL OF WIRE

1. Remove the ‘hairpin’ clip from spindle.

2. Position the spool of wire so that when it is placed on the

spindle, wire will be drawn to the feed roll from the bottom of

the spool. The spool should be held so that the index hole

on the back will engage the lug on the spindle.

3. Slide the spool onto the spindle until it engages the lug. Lock

in place with the hairpin clip.

4. Loosen the brake screw in the center of the spindle hub,

then tighten it just enough to prevent coasting of the spool

when wire is drawn from it. Too much pressure will load the

wire feed motor unnecessarily. Too little pressure will permit

the spool to over-run, causing the wire to kink and tangle.

5. Thread the wire on to the accessory support assembly as

described in Section E.

6. When wire coils are to be used instead of spools, mount wire

reel on spindle as though it were a spool (see 1 and 3

above). Remove thumbnuts and cover plate from reel.

Remove coil from its package, but do not remove it binding

wires. Slide coil onto reel so that wire will be drawn from

bottom of coil (starting end for a coil is always the outer end).

Replace reel cover plate and thumbnuts. Cut off coil tie wires

and thread wire to torch as covered in 4 and 5 above.

E. ADJUSTING THE ACCESSORY SUPPORT ASSEMBLY

When a new wire size or type is to be used, set the pressure roll

adjusting as follows:

1. Round off the free end of the welding wire with a file to

remove sharp edges and burrs which might damage the

conduit liner.

2. Release the clapper and unscrew the pressure adjusting

knob until the pressure spring is free.

3. Thread the wire through the inlet and outlet guides of the

accessory support, and 3 or 4 inches into the torch conduit.

4. Engage the clapper making sure the wire is held in the feel

roll groove.

5. Tighten the pressure adjusting knob until the wire is firmly

against the feed roll -- do not overtighten. The spring

pressure applied should be the minimum required to pro-

vide positive, nonslip wire feed. Too little pressure will result

in wire slippage while excessive pressure will scar and

deform the wire. Further adjustment can be made after the

wire feed is put into operation. Note that a light spring

(182W55) is installed on the accessory support for use with

soft and small diameter hard wire. For larger diameter hard

wire, replace this spring with a heavy spring (182W54)

supplied with the unit.

F. FEEDING WIRE AND ADJUSTMENTS

With wire engaged in the accessory support per section IV-E,

feed wire through torch conduit and torch as follows:

1. Remove nozzle and contact tip from torch.

2. Operate remote INCH switch until “cold” wire protrudes from

torch front end. Release the INCH switch.

3. Slide the contact tip over the end of the wire and secure to

torch. Replace the torch nozzle.

4. Reoperate the remote INCH switch and check for wire feed

slippage on the accessory support assembly. Tighten (or

loosen) the pressure adjusting knob until the wire feeds

smoothly.

5. Refer to the appropriate welding control instruction booklet

for remaining operating procedures.

V. INSTALLATION OF THE FOUR ROLL DRIVE

A. FOUR ROLL DRIVE ASSEMBLY

To install the four roll drive assembly on an EH-10 Motor-Gear

Unit proceed as follows:

1. Remove the jam nut (EH-3) or thumbscrew (EH - 10) and

washer from the output shaft of the motor-gear unit.

2. Fit the Gear and Insulator Assembly (P/N 999179) onto the

motor-gear unit shaft and engage the Key (P/N 28N33).

3. Insert the 1/4-in.-20 x 1/2-in. panhead screw (P/N 61307087),

1/4-in. bell washer (P/N 950783), and 1/4-in. flatwasher (P/

N 64309431) in the motor-gear unit shaft to secure the gear

and insulator assembly.

4. Position the four roll drive assembly on the motor-gear unit

insulator ring and secure by tightening the 5/16-18 capscrew

at the bottom of the assembly. Be sure the gear and

insulator assembly meshes correctly with the lower feed

roll gears in the four roll drive assembly.

B. FEED ROLLS

To install the desired feed roll kit (see Table l) proceed as

follows:

1. Position the feed rolls over the four gear assembly hubs

aligning the feed roll holes with the gear assembly holes.

2. Secure the feed rolls to the gear assemblies using the No. 8-

32 x 5/8-in. screws and lockwashers supplied.

C. CENTER WIRE GUIDE

To install the proper center wire guide (see Table l) proceed as

follows:

A. GENERAL MAINTENANCE

Little maintenance is required to keep the welding head in top

operating condition. It is important, however, that moving parts

such as feed and pressure rolls, wire feed motor, etc., be kept

clean and free of dust or dirt. Cleaning is best accomplished by

regularly blowing off these parts with dry compressed air. This

should be done once for every eight hours of operating time,

more often if necessary.

B. LUBRICATION OF DIGITAL MOTOR-GEAR UNIT

The EH-10A digital motor-gear unit is lubricated with a heavy

duty grease when assembled at the factory and should not

require further lubrication unless disassembled. If disassembled
