Visually inspect the grinder to ensure the motor, power cord, grinding head and related components
are all in good working condition
Ensure the proper collet size is selected for the diameter of tungsten to be ground; for your
convenience, two collets are stored in the top of the head assembly
Take care when grinding tungsten electrodes to ensure your safety and the safety of others in adjacent
areas

Adjusting the Tungsten Contact Point on the WheelSafety Information
Make sure the motor is unplugged or battery disengaged
Remove the two lower housing screws and lift the upper
housing assembly o the lower housing, exposing the
diamond wheel
Lock head stock in place and loosen mandrel screw
Remove the screw and washer from the mandrel, reverse
sides or replace wheel as needed
Tighten mandrel screw, replace the upper housing and
tighten head screws
Replacing or Flipping the Wheel
Use compressed air to clean the grinder head of tungsten
dust or debris after every 8 hours of use.
Be sure all screws and collets are tight
Check the power cord for wear or breakage periodically
Check collets for excessive wear
Regular Maintenance Tips
Make sure the unit is unplugged and loosen the disc screw
Rotate the collet disc so the tungsten will contact another
spot on the diamond wheel
To locate the spot where the tungsten meets the wheel,
insert tungsten and look through the viewing slot located
in the lower housing
When the tungsten contact position has been set, tighten
the disc screw to lock the disc in place
When the top diamond surface of the wheel has been worn-
out, ip the wheel over and adjust as noted above

Adjusting the Grinder Angle (
on DX Model only
)
Loosen set screw to allow the brass collet holder to pivot for
grinding dierent taper angles (
SEEFIGURE-2
)
Once desired angle is located, tighten set screw in the collet
holder and grind tungsten to desired taper
When the Outer Diameter of the Wheel is Worn
Loosen set screw and turn the brass screw to advance the collet
(and corresponding tungsten contact point) toward the center of
the wheel (
SEEFIGURE-2
)

angle
With the correct collet in the angle disc, insert the tungsten electrode into the collet
(SEE FIGURE-1) and rotate for one 360º rotation while exerting consistent pressure so the
tungsten is contacting the grinding wheel Repeat until tungsten reaches desired taper
FIGURE-1
Grinding the Electrode Taper
Release pressure from grinding wheel after each rotation of the
tungsten electrode
Releasing in this way allows wheel to cool and greatly extends
wheel life
Changing the Diameter of the Tungsten
Identify the proper size collet from the two stored in the top of the
head assembly Your grinder was shippped from the factory with
1/16” (16mm), 3/32” (24mm) and 1/8” (32mm) collets A 040”
(10mm) collet is available as an option
Remove collet using wrench supplied with your grinder, and
switch with the desired collet in the angle disc assembly
t
Selecting the Grind Angle
Follow your equipment supplier’s suggested grind angle specications or perform tests to
determine the optimal electrode preparation for your application
Refer to the chart below for general guidelines
15° 35° 45° 60° 90° 120° 180°
Sharper Electrode (Narrow Angle) Blunter Electrode (Wider Angle)
Wider weld bead Improved arc stability Narrower weld bead Increased potential for arc wander
Easier arc starting Less weld penetration Harder arc starting Better weld penetration
Less amperage Shorter electrode life More amperage Longer electrode life

t
Grinding a Tip Flat
Electrodes with tip ats deliver improved arc characteristics, longer tip life, improved
arc starting, and reduced tungsten contamination
FIGURE-4
The grinder is equipped with four holes: 040” (10mm), 1/16”
(16mm), 3/32” (24mm) and 1/8” (32mm) in the top housing to
produce a tip at on the end of the tungsten electrode
To Produce a Tip Flat:
Insert the tungsten into the correct size hole in the top of the
housing (
SEEFIGURE-4
)
Gently press the tungsten into the diamond wheel and rotate
for one 360º rotation while exerting pressure so the tungsten
touches the wheel Remove electrode and check for desired tip
at Repeat as needed
t
Cutting the Tungsten
Gently press electrode until it contacts the grinding wheel
rotating it to form a groove completely around the tungsten
While you can cut the electrode in half from one side it will cause excessive wheel wear and
shorten wheel life Instead, cut a groove around the electrode approximately half the thickness
of the material Turn unit o, insert electode into the appropriate size collet and gently snap the
tungsten in two Done properly, this procedure won’t splinter or damage the integrity of the
electrode material
Note: Take care when cutting electrodes so as not to bind the tungsten by wedging it
between the wheel and the machine housing
FIGURE-5
The grinder is equipped with a slot for cutting tungsten to length
or for cutting o contaminated portions
Note: To ensure the highest-quality welds, cut contaminated
portions of the electrode prior to sharpening so as not to
contaminate the diamond wheel
Place electrode in the angle slot so the desired portion of the
tungsten to be cut lines up with the edge of the diamond wheel
(
SEEFIGURE-5
)
Note: Reset grind angle after adjusting the contact point to an
unused surface of the grinding wheel
For A Long Taper
Loosen the collet disc screw and lower the collet disc so the point
of entry of the tungsten is closer to the diamond wheel
(
SEEFIGURE-3
)
Note that the lower the disc, the longer the point Conversely,
the higher the disc, the shorter the angle
Note: For a longer angle taper, the tungsten must contact the
outer most diameter of the wheel because a longer taper requires
more contact with the grinding surface

MAXIMIZE ARC STARTS AND IMPROVE ARC TIME
WITH HIGH-QUALITY TUNGSTEN ELECTRODES
Selecting the proper tungsten electrodes greatly improves weld quality and productivity while lowering
costs for your Gas Tungsten Arc Welding (GTAW/TIG) and Plasma Arc Welding (PAW) operations.
t
Choose Electrodes from a Trusted Source
t
Determine the Best Tungsten for Your Application
Although tungsten electrodes may look the same from one company to another,
high-quality tungsten has been manufactured to ensure a dense grain structure
which allows for better migration of oxides to the tip of the electrode
With high-quality tungsten, you’ll experience easier arc starting, improved arc time
and better weld quality with minimized contamination Arc-Zonecom’s ArcTime™
and Amplify™ brand electrodes are sourced from the world’s nest producers and
meet or exceed ISO 6848 and AWS A512 standards Arc-Zonecom ® delivers the industry’s most
complete line of premier tungsten electrodes including: ArcTime™, Amplify™, CK Worldwide™,
DGP® Multi-Strike™, Miller®, and Wolfram®
Since the development of the TIG welding process, many improvements have been made
in the production of electrodes Most signicant is the addition of oxides to pure tungsten,
creating tungsten alloys that provide the same level of emission as pure tungsten at much lower
temperatures, improving starting performance of the electrode, arc stability, and tip life
Each oxide has a dierent physical characteristic aecting tungsten performance Electrodes are
color coded, indicating the type of oxide used in the mix Note: Color-coding
is not standardized for all mixes, and it varies from the US, Europe, and Japan
For most hand-held welding operations, Arc-Zone® recommends the
ArcTime™ Hybrid Tungsten Electrode For other applications, particularly
automated welding, the best way to determine which tungsten alloy is best
suited for your application is through testing The list on the following page
is provided as a guide

Tungsten Material Blend Guide

11 / 12
Dierent electrode materials will vary slightly from these guidelines Use of gases other than Argon
will also change the recommended currents Use this chart as a general guide Also keep in mind
that for a given amount of amperage, larger diameter electrodes will last longer but will be harder
to start Excessive current will cause the electrode to melt and drop o Insucient current will lead
to an unstable arc
