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

ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks
or severe burns. The input power circuit and
machine internal circuits are also live when power is
on. Incorrectly installed or improperly grounded
equipment is 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.

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.

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.
GRINDING can cause FIRE OR EXPLOSION.

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
clothing to prevent burns.
OVERUSE can cause OVERHEATING
