Tung_Grind 2010−05
Protect yourself and others from injury — read and follow these precautions.
1-1. Symbol Usage
DANGER! − Indicates a hazardous situation which, if
not avoided, will result in death or serious injury. The
possible hazards are shown in the adjoining symbols
or explained in the text.
Indicates a hazardous situation which, if not avoided,
could result in death or serious injury. The possible
hazards are shown in the adjoining symbols or ex-
plainedin the text.
NOTICE − Indicates statements not related to personal injury.
Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-
bols and related instructions below for necessary actions to avoid the
hazards.
1-2. Tungsten Grinding Hazards
The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-4. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this unit.
During operation, keep everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touchinglive electrical parts can cause fatal shocks
or severe burns. The input power circuit and
machineinternal circuits are also live when power is
on. Incorrectly installed or improperly grounded
equipmentis a hazard.
Do not touch live electrical parts.
Wear dry, hole-free insulating gloves and body protection.
Disconnect input power before installing or servicing this
equipment.
Properly install this equipment according to its Owner’s Manual
and national, state, and local codes.
Frequently inspect input power cord for damage or bare wiring −
replace cord immediately if damaged − bare wiring can kill.
Turn off all equipment when not in use.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Keep all panels and covers securely in place.
Grinding produces dust. Breathing this dust can be
hazardous to your health.
GRINDING DUST can be hazardous.
Do not breathe the dust.
Use local exhaust (forced ventilation) to remove dust or wear an
approved respirator.
Grinding dust from thoriated electrodes contains low-level radio-
active material. Consider using tungsten containing ceria,
lanthana,or yttria instead of thoria.
Properly dispose of grinder dust in an environmentally safe way.
Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals and consumables.
GRINDINGcan cause FIRE OR EXPLOSION.
Do not grind where flying sparks can strike
flammablematerial.
Protect yourself and others from flying sparks
and hot metal.
Be alert that sparks and hot materials from grinding can easily go
throughsmall cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
FLYING SPARKS can injure.
Wear a face shield to protect eyes and face.
Shape tungsten electrode only on grinder with
properguards in a safe location wearing proper
face, hand, and body protection.
Sparks can cause fires — keep flammables away.
HOT PARTS can burn.
Do not touch hot parts bare handed.
Allow cooling period before working on equip-
ment.
To handle hot parts, use proper tools and/or
wear heavy, insulated welding gloves and
clothingto prevent burns.
OVERUSE can cause OVERHEATING
Allow cooling period; follow rated duty cycle.
Keepair holes free of dust; clean if necessary.
READ INSTRUCTIONS.
Read and follow all labels and the Owner’s
Manualcarefully before installing, operating, or
servicing unit. Read the safety information at
the beginning of the manual and in each
section.
Use only genuine replacement parts from the manufacturer.
Perform maintenance and service according to the Owner’s
Manuals, industry standards, and national, state, and local
codes.

OM-230 915 Page 2
MOVING PARTS can injure.
Keep away from moving parts.
Keep all doors, panels, covers, and guards
closed and securely in place.
Have only qualified persons remove doors, panels, covers, or
guards for maintenance and troubleshooting as necessary.
Reinstall doors, panels, covers, or guards when maintenance is
finishedand before reconnecting input power.

SECTION 3 − SPECIFICATIONS
3-1. Description
The TTG Plus cuts, grinds, and faces tungsten electrodes used in the TIG (GTAW) welding process. Additional fea-
tures and benefits of this unit are:
•Electrodes are sharpened to conform to recognized standards.
•The replaceable grinding wheel is diamond-coated on both sides.
•The grinding wheel has an offset edge for easy cutting − an industry exclusive!
•The head assembly allows for different electrode angles and diameters.
•The unit can be hand operated, or bench-mounted using the supplied mounting bracket.
Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires. Use local exhaust (forced
ventilation) at the grinder or wear an approved respirator.
Read MSDS for safety information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust from
thoriatedelectrodes contains low-level radioactive material. Properly dispose of grinder dust in an environmentally safe way. Wear
proper face, hand, and body protection. Keep flammables away.

804 811
!Grinding the tungsten elec-
trode produces dust and fly-
ing sparks which can cause
injury and start fires. Use lo-
cal exhaust (forced ventila-
tion) at the grinder or wear an
approvedrespirator.
Read MSDS for safety infor-
mation. Consider using
tungsten containing ceria,
lanthana,or yttria instead of
thoria. Grinding dust from
thoriated electrodes con-
tains low-level radioactive
material. Properly dispose
of grinder dust in an environ-
mentally safe way. Wear
proper face, hand, and body
protection.Keep flammables
away.
1 Grinder
2 Exhaust (Vacuum) System
The grinding head is designed to
accept a 1−1/4 in. (32 mm) exhaust
(vacuum) hose.
Connect the grinder to the exhaust
(vacuum) hose as shown.
The optional protective cover/
adapter can also be used to con-
nect the exhaust (vacuum) hose to
the grinder.

804 719
!Grinding the tungsten electrode
producesdust and flying sparks
which can cause injury and start
fires. Use local exhaust (forced
ventilation)at the grinder or wear
an approved respirator.
Read MSDS for safety informa-
tion. Consider using tungsten
containingceria, lanthana, or yt-
tria instead of thoria. Grinding
dust from thoriated electrodes
contains low-level radioactive
material. Properly dispose of
grinder dust in an environmen-
tally safe way. Wear proper face,
hand, and body protection. Keep
flammablesaway.
Do not exert excessive pressure on
the grinding wheel or the life of the
wheel will be shortened.
Use a rough grinding wheel to
sharpenlarge electrodes.
Wait until grinding wheel stops be-
fore restarting grinder.
1 Tungsten Electrode
To Sharpen Electrode:
Determine diameter of electrode and
desiredsharpening angle.
Turn on grinder. Insert electrode in cor-
respondinghole in grinder.
Slowly turn the electrode until tip is
sharpenedevenly. If the electrode is not
turned the tip will be flat ground to the
selectedangle.
To Face Grind Electrode:
Determine diameter of electrode.
Turn on grinder. Insert electrode in cor-
responding hole at front of grinding
head. Grind the electrode tip until
square.
To Cut Electrode To Length:
(For Orbital Or Manual Welding):
2 Cutting Slot
Turn on grinder. Insert electrode in cut-
ting slot and turn electrode slowly until
cut.
An optional cutting device is avail-
ablefor larger electrodes. See Sec-
tion 7.
Turn grinder off.
