MODELS DGP-3 & DGP-3-V2

The DGP-3 Tungsten Welding Electrode Grinder is designed specifically 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 offers 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 offer 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 flexible 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 finish it produces. Wheel

rotation, viewed from the left end of the grinder, is clockwise. Both wheels have clear Plexiglass safety eyeshields.

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 notifications 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 office

if you would like more information about this issue. In addition, we offer 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 deflect quickly off the wheels from grinding. The

vacuum system offers 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 filters are in stock at the factory for immediate shipment. Installation instructions come with

replacement filters and is a simple process.
