Very often sparks fly off from the joint area.
D Wear approved face shield or safety goggles
with side shields.
FLYING SPARKS can injure.
D Wear protective garments such as oil-free, flame-resistant leather
gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
Synthetic material usually does not provide such protection.
D Protect others in nearby areas by using approved flame-resistant or
noncombustible fire curtains or shields. Have all nearby persons
wear safety glasses with side shields.
D Do not touch hot parts bare handed.
D Allow cooling period before working on equip-
ment.
HOT PARTS can burn.
D To handle hot parts, use proper tools and/or wear heavy, insulated
welding gloves and clothing to prevent burns.
The tong tips, tongs, and linkages move during
operation.
MOVING PARTS can injure.
D Keep away from moving parts.
D Keep away from pinch points.
D Do not put hands between tips.
D Keep all guards and panels securely in place.
D OSHA and/or local codes may require additional guarding to suit
the application.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
FUMES AND GASES can be hazardous.
D Keep your head out of the fumes. Do not breathe the fumes.
D If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instructions for metals, consumables, coat-
ings, cleaners, and degreasers.
D Work in a confined space only if it is well ventilated, or while wearing
an air-supplied respirator. Always have a trained watchperson
nearby. Welding fumes and gases can displace air and lower the
oxygen level causing injury or death. Be sure the breathing air is
safe.
D Do not weld in locations near degreasing, cleaning, or spraying op-
erations. The heat and rays of the arc can react with vapors to form
highly toxic and irritating gases.
D Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and while wearing an air-supplied
respirator. The coatings and any metals containing these elements
can give off toxic fumes if welded.
1-3. Additional Symbols For Installation, Operation, And Maintenance
FIRE OR EXPLOSION hazard.
D Do not install or place unit on, over, or near
combustible surfaces.
D Do not install or operate unit near flammables.
D Do not overload building wiring − be sure power supply system is
properly sized, rated, and protected to handle this unit.
FALLING EQUIPMENT can injure.
D Use equipment of adequate capacity to lift and
support unit.
D Follow the guidelines in the Applications Manual
for the Revised NIOSH Lifting Equation (Public-
ation No. 94−110) when manually lifting heavy parts or equipment.
D Secure unit during transport so it cannot tip or fall.
READ INSTRUCTIONS.
D Read and follow all labels and the Owner’s
Manual carefully before installing, operating, or
servicing unit. Read the safety information at
the beginning of the manual and in each
section.
D Use only genuine replacement parts from the manufacturer.
D Perform maintenance and service according to the Owner’s
Manuals, industry standards, and national, state, and local
codes.
FLYING METAL or DIRT can injure eyes.
D Wear approved safety glasses with side
shields or wear face shield.
ELECTRIC AND MAGNETIC FIELDS (EMF)
can affect Implanted Medical Devices.
D Wearers of Pacemakers and other Implanted
Medical Devices should keep away.
D Implanted Medical Device wearers should consult their doctor
and the device manufacturer before going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating
operations.
OVERUSE can cause OVERHEATING.
D Allow cooling period; follow rated duty cycle.
D Reduce duty cycle before starting to weld
again.
