SECTION 4 – OPERATION
WARNING
ELECTRIC SHOCK can kill; TWO TIMES
NORMAL OPEN-CIRCUIT VOLTS exists
between electrode holders of opposite
polarity.
•
Always wear dry insulating gloves.
•
Insulate yourself from work and ground.
•
Do not touch live electrical parts.
•
Keep all panels and covers securely in place.
•
Do not touch electrode holders of opposite polarity
at the same time.
•
Separate electrode holders of opposite polarity to
prevent contact.
•
See ANSI Z49.1 and OSHA TITLE 29, CHAPTER
XVII, PART 1910, Subpart Q.

•
Do not weld near flammable material.
•
Watch for fire; keep extinguisher nearby.
•
Do not locate unit over combustible surfaces.
•
Do not weld on closed containers.
•
Allow work and equipment to cool before handling.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
•

•
Wear correct eye, ear, and body protection.
FUMES AND GASES can be hazardous
to your health.
•
Keep your head out of the fumes.
•
Ventilate area, or use breathing device.
•
Read Material Safety Data Sheets (MSDSs) and
manufacturer’s instructions for material used.
HOT SURFACES AND EQUIPMENT can
cause burns.
•
Allow equipment to cool before inspecting or servic-
ing.
•
Wear correct hand and body protection.
•
Do not place anything on or near this unit during op-
eration.
MAGNETIC FIELDS FROM HIGH CUR-
RENTS can affect pacemaker operation.
•
Pacemaker wearers keep away.
•
Wearers should consult their doctor before going
near arc welding, gouging, or spot welding opera-
tions.
See Safety Precautions at beginning of manual for ba-
sic welding safety information.
