1 . GENERAL DESCRIPTION

1. GEnEral DEscrIptIOn
The DGP-2 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 cuts these electrodes to precise lengths using a micrometer. 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 balanced for vibration-free rotation. The motor
housing is compact and the unit has ample side clearance on the grinding and aluminum oxide wheels. Wheel
guards are secured to the shaft by threaded nuts and safety eyeshields are also included.
The DGP-2 and DGP-2-V2 Tungsten Electrode Grinders offer precise grinding for your precision welding needs.
The DGP-2 consists 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-2-V2 adds foam-insulated cabinet, vacuum system for dust collection, and a flexible spotlight in addition
to the DGP-2 features. The DGP-2 can be upgraded later to a DGP-2-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 Plexiglas safety eyeshields.

VACUUM SYSTEM OVERVIEW

The DGP-2-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-2 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 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 motor 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 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.
