and DGP-M2-V2
1. GENERAL DESCRIPTION
DGP-M2
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
precision scale
and
an adjustable indexer block. 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
cutting
wheels.
Wheel guards are secured to the shaft by threaded nuts and safety eyeshields are also included.
DGP-M2
and DGP-M2-V2 Tungsten Electrode Grinders offer precise grinding for your precision welding needs. The
DGP-M2
consists of a horizontal axis grinder that can be pedestal mounted, a diamond grinding wheel and assembly on
the
right
side,
and
a
diamond cutting
wheel
for
cutting an electrode
to
a precision
length
on the left side.
The
DGP-M2-V2 adds
a
foam-insulated cabinet,
vacuum system for dust collection,
and a flexible spotlight in addition to
the
DGP-M2
features.
The DGP-M2
can be upgraded later to a DGP-M2-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
cutting
assembly on the left
side also provides excellent visibility and
is easy to operate.
Wheel rotation, viewed from the left end of the grinder, is
clockwise.
VACUUM SYSTEM OVERVIEW
The
DGP-M2-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, which
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-M2
can
later upgrade their systems to add the vacuum system if
chosen
later.
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
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 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.
