MODELS DGP-3 & DGP-3-V2
1. GENERAL DESCRIPTION
The DGP-3 Tungsten Welding Electrode Grinder is designed specically for the longitudinal grinding of the conical or
tapered points on tungsten welding electrodes from .040” (1.0mm) to 3/16” (4.8mm) in diameter. This model also oers a
multi-purpose grinding wheel for other shop uses. The grinder is equipped with a completely enclosed ball bearing motor
and a rotor and shaft assembly that is dynamically balance for vibration-free rotation. The motor housing is compact and
the unit has ample side clearance on the grinding and aluminum oxid wheels. Wheel guards are secured to the shaft by
threaded nuts and safety eyeshields are also included.
The DGP-3 and DGP-3-V2 Tungsten Electrode Grinders oer precise grinding for your precision welding needs. The
DGP-3 constists of a horizontal axis grinder that can be pedestal mounted, a diamond grinding wheel and assembly on
the right side, and a general purpose aluminum oxide wheel for general shop uses on the left side. The DGP-3-V2 adds
foam-insulated cabinet, vacuum system for dust collection, and a exible spotlight in addition to the DGP-3 features. The
DGP-3 can be upgraded later to a DGP-3-V2.
The diamond grinding wheel on both grinders is on the right side of the machine and the surface rotates toward the
electrode which provides consistent and repeatable points from each grind. The grinding surface faces right and the right
wheel enclosure housing supports the electrode grinding assembly in addition to a Point Flat Dresser Block. The location
of the area of contact between the diamond grinding wheel and the tungsten electrode is visible to the operator at all
times, which allows for excellent control of the grinding operation. After repeated use, a groove will eventually be worn
into the wheel at the contact point. The contact point should then be adjusted downward slightly to the next unused spot
on the diamond grinding wheel. The grinding assembly on the left side also provides excellent visibility and is easy to
operate for general grinding use, but is not recommended for tungsten because of the inferior nish it produces. Wheel
rotation, viewed from the left end of the grinder, is clockwise. Both wheels have clear Plexiglass safety eyeshields.
VACUUM SYSTEM OVERVIEW
The DGP-3-V2 comes with a tool cabinet and integrated vacuum system for the collection of tungsten dust. This feature
has become very popular due to notications in the past few years about the danger of inhaling dust from the commonly
used 2% Thoriated tungsten, is a known radioactive cancer-causing element. Please contact your local OSHA oce
if you would like more information about this issue. In addition, we oer free samples of non-radioactive alternative
tungsten, which performs better in most applications. Users of the DGP-3 can later upgrade their systems to add the
vacuum system if later chosen.
It is impossible to contain all of the lightweight dust particles that deect quickly o the wheels from grinding. The
vacuum system oers a way of collecting the majority of the dust that is produced while grinding tungsten electrodes.
Each side of the grinder has vacuum holes and hoses to collect dust. To maximize the suction power, use the valves at
the back of the grinder moto to direct the suction to the side you are using. If you are using both sides at the same time,
leave both sides open. However, if you are only using one side, close the valve on the opposite side and you will increase
the suction power to the side you are using.
Replacement vacuum lters are in stock at the factory for immediate shipment. Installation instructions come with
replacement lters and is a simple process.

• Wear protective hair covering to contain long hair.
• Wear safety glasses and a facemask.
• Never operate power tools when tired, intoxicated, or when taking medication that may cause drowsiness.
• Work area should have sucient lighting.
• A proper electrical outlet should be available for the tools. A three-prong plug should be plugged directly into a
three-pronged outlet. Extension cord should be the correct gauge.
• Keep visitors at a safe distance from the work area.
• Always unplug grinder prior to inspection.
• Read this manual thoroughly for specic adjustments and operating procedures.
• Do not perform “make-shift” repairs. Any part that is damaged should be promptly replaced.
• Only use the grinder for its intended purpose. Do not use it for a job it was not designed for.
• Make sure that the griner is o before plugging it in.

6. OPERATOR SHOULD KNOW HOW TO USE THE GRINDER
• Only use the grinder for its intended purpose. Do not use it for a job it was not designed for. Grinding parts other
than tungsten will severely decrease wheel and equipment life.
• Unplug the grinder when changing accessories, such as collets, wheel, or other replacement parts.
• Avoid accidental start-up. Make sure that the grinder is in the o position before plugging it in.
• Do not force the grinder. It will most eciently at the rate for which it was designed. Consult the “Recommended
Minimum Cutting and Grinding Time for New Electrodes” sticker on the grinder to determine optimum rate of speed.
• Use recommended accessories. Use of improper accessories may cause risk of injury of person or accelerated wear
on the grinder.
• Handle the tungsten and grinder correctly. Consult grinder operation procedures in this manual and handle tungsten
with pin vise whenever possible to protect hands from possible injury.
• Feed tungsten into grinding wheel against eh direction of rotation of the wheel.
• Turn the wheel o if it jams. A wheel jams when it digs too deeply into the tungsten (the motor force keeps it stuck in
the tungsten).
• Never leave the grinder unattended. Turn the grinder o rst and do not leave until it comes to a complete stop.
• Never stand or lean on the grinder. Serious injury could occur if the grinder is tipped or if the cutting tool is
unintentionally contacted.
• Keep hands away from moving parts and cutting surfaces.
7. OPERATOR SHOULD BE PREPARED FOR THE JOB
• Wear proper apparel. Do not wear loose clothing gloves, neckties, bracelets, or other jewelry which may get caught
in moving parts of the machine.
• Wear protective hair covering to ctonatin long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses. Prescription glasses have only impact resistant lenses.
• Wear face mask or dust mask.
• Be alert and think clearly. Never operate power tools when tires, intoxicated, or when taking medications that
cause drowsiness.
8. GRINDER SHOULD BE MAINTAINED PROPERLY
• Always unplug grinder before inspection.
• Keep the grinder clean for safest operation.
• Remove adjusting keys and wrenches. Form a habit of checking that keys and adjusting wrenches are removed
before the grinder is turned on.
• Keep all safety guards in place and in good working order.
• Keep all parts in working order. Check to determine that the guard or other parts will operate properly and perform
their intended functions.
• Check for damaged parts and alignment of moving parts, binding of moving parts, breakage of mounting parts, and
any other condition that may aec tthe grinders operation.
• Consult DGP factory for replacement parts at [phone].
9. WORK AREA SHOULD BE READY FOR THE JOB
• Keep work area clean.
• Do no use power tools in dangerous environments, such as damp or wet locations. Do not expose power tools to
rain.
• Work area should be properly lighted.
• The proper electrical outlet should be available for the tool. For 110V, a three prong plug should be plugged directly
into a three prong outlet and/or extension cord.
• Keep visitors a safe distance from work area and keep children out of work place. Use padlocks, master switches,
and remove starter keys to prevent any unintentional use of power tools.

MOUNTING THE DGP-3
The DGP-3 stand alone grinder (without vacuum system and cabinet) should be mounted to a solid horizontal surface
(mounting hardware is not provided).
If mounted to a metal cabinet or pedestal, align the mounting holes with the corresponding holes in the cabinet or
pedestal. Insert a 1/4”-20 X 1 1/4” hex head bolt with at washer beneath the head of the grinder. From the bottom of
the cabinet or pedestal, place a 1/4” at washer and 1/4”-20 hex nut onto the bolt extension. Tighten only until the space
between the grinder base and the cabinet or pedestal is 1/8”. Using a second nut on each bolt, tighten against the rst
to prevent loosening by vibration.
If mounted to a wooden bench top, use 1/4” wood screws that are 1-1/4” long with at washer beneath the heads.
Tighten screws until the space between the grinder base and the bench is 1/8”.
ELECTRODE GRINDING ASSEMBLY
THE BASICS
The Electrode Grinding Assembly is attached to the right wheel housing (refer to Figure 1 for the general arrangement of
the assembly). It provides the means to support an electrode in a xed position relative to the diamond-grinding surface
through an electrode guide collet that matches the electrode diameter. The electrode is brought into gentle contact with
the diamond-grinding surface and at the same time is rotated slowly in one direction between the operator’s thumb and
forenger. As an alternative, pin vises are also provided to hold the tungsten during rotation. Note: all positioning and
adjustement should be made before turning on the grinder.
SYMPTOMS POSSIBLE CAUSE(S) CORRECTIVE ACTION
Grinder won’t start
1. Blown line or tripped circuit
breaker
1. If fuse is blown, replace with fuse of proper size. If
breaker is tripped, reset it.
2. Low line voltage 2. If voltage is less than rated, check size of wiring from
main switch on property. If OK, contact power company.
3. Material wedged between
wheel and guard 3. Remove material wedged between wheel and guard.
Excessive vibration
1. improper mounting of grinder
or accessories 1. Remount
2. Improper wheel mounting
2. Remove both wheels then remount wheels, but rotate
one wheel 1/4 turn with respect to its previous position.
The other wheel would retain its original position.
Grooved wheel
1. Electrode pushed with
excessive force 1. Use recommended grinding times table.
2. On steep angled tungsten,
collet touching wheel
2. Use short collets available from Diamond Ground
Products.
Motor is overheating 1. Motor not turning freely
(without power) 1. Clean around wheels & shaft. Then replace bearings.

7DGP-3 & DGP-3-V2 User Manual Rev:B • 05/16/2023
OPERATION INSTRUCTIONS
Please refer to Figure 1 below for the optimum location of the electrode point contact area with respect to the grinding
surface. In the position shown, the motion of the diamond grinding wheel surface is parallel to the centerline of the
electrode to accomplish longitudinal grinding of the electrode point. When grinding very steep angles, such as 10°, be
careful that the electrode guide collet does not make contact with the diamond grinding wheel. This can contaminate
the wheel and reduce the life of the wheel signicantly. For these types of angles, you may need to consult the factory to
obtain optional short collets that are available for these applications.
Refer to Figure 2 below for use with the following operation instructions:
1. If the tungsten you are using is already at at the end, like new tungsten straight out of the box, proceed to Step 4.
2. Locate the Block Point Flat Dresser (DGP-F180) attached at the 12 o’clock position of the right side wheel cover.
Find the hole that matches the diameter of your tungsten and turn on the grinder.
3. Select the electrode guide collet with the hole diameter closest to the tungsten electrode diameter and position it
in the electrode guide collet tube. Notice that the collet has been beveled on a 15° angle at the front or exit of the
collet. With this surface parallel to the grinding wheel surface, tighten the set screw to hold it in place. The back,
or entrance, end of this collet has been milled down to its center line to make it easy to insert the electrode for
grinding.
4. Adjust the angular position of the electrode grinder assembly to the desired included angle of grind for the
electrode point using the angle adjustment handle (Handle A).

ELECTRODE GRINDING ASSEMBLY
(CONT.)
1. Left to right positioning: Adjust the position of the
electrode grinder assembly using the horizontal
adjustment knob (Handle B) to place beveled surface
of the electrode guide collet approximately 1/64”
from the grinding surface.
2. Slip a tungsten electrode into and through the
electrode guide collet to determine where it will
contact the grinding disk surface.
3. Up and down positioning: Adjust the electrode
grinder assembly using the vertical adjustment knob
(Knob C) so that the tungsten electrdoe will contact
the actual grinding surface.
4. Remove the tungsten electrode from the electrode
guide collet.
5. Put the eyeshield in place and start the grinder.
Slide the tungsten electrode into and through the
electrode guide collet and twirl the electrode (or the
pin vise holding the electrode) slowly in one direction
between thumb and forenger as it approached
and makes contact with the grinding surface. To
retain maximum symmetry of the point, try to keep
from moving the electrode side to side within the
collet. The best technique for this is to constantly
lean the electrode against the inside surface of
the collet while turning. Continue grinding until
the desired sharpness is obtained. Make sure to
continue rotation as the electrode is backed o from
the wheel or a at spot may occur along the point.
Contamination of the wheels can occur by using the
diamond grinding and cutting wheels as all-purpose
shop wheels. If you grind tools or other metal items,
other than electrodes, there is always the risk of
contaminating the wheels.
In addition to proper positioning and avoiding
contamination, use the recommended grinding times in
Table 1 below to increase the longevity of the diamond
grinding wheels. The wheel can be used with very
limited wear by working according to these guidelines.
Wear of the wheel will double if the grinding time is
reduced by one half using more applied force and wear
will triple if the time is reduced by one third. Be patient
and do not gouge the wheel!
For users requiring extreme tolerances, a laser cut tip/
at gauge is available from Diamond Ground Products
to accurately measure tip diameter. See page 13 for the
part number. Also note, a microscope or comparator
can be used to verify the angle (taper) of the grind in a
very precise and ecient manner.
Consult Illustrated Parts Lists on the following pages
and
