^ As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone
without going below the minimum. This Lens Shade Selector Guide was adapted from ANSI Z49.1, 2012.
WELDING can cause fire or explosion
Sparks and spatter fly off from the welding arc.
The flying sparks and hot molten metal, weld spat-
ter, hot work piece and hot equipment can cause
fires and burns.
Welding on closed containers, such as tanks, drums, or pipes, can cause
them to blow up.
Accidental contact of electrode or welding wire to metal
objects can cause sparks, overheating, fire, or explosion. Check that the
area is safe before doing any welding.
•
Protect yourself and others from flying sparks and hot metal.
•
Do not weld where flying sparks can strike flammable material.
•
Remove all flammables within 35 ft (10.7 m) of the welding arc. If this
is not possible, tightly cover them with approved covers.
•
Be alert that welding sparks and hot materials from welding can easily
go through small cracks and openings to adjacent areas.
•
Watch for fire, and keep a fire extinguisher nearby.
•
Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
•
Do not weld on containers that have held combustibles or on closed
containers such as tanks, drums, or pipes unless they are properly
prepared according to AWS F4.1 and AWS A6.0.
•
Do not weld where the atmosphere contains flammable dust, gas, or
liquid vapours (gasoline for example).
•
Connect work cable to the work as close to the welding area as practi-
cal to prevent welding amperage from travelling long, possibly un-
known paths and causing electric shock and fire hazards.
•
Use only correct fuses or circuit breakers. Do not oversize or bypass
them.
•
Cut off welding wire at contact tip when not in use.
•
Wear body protection made from durable, flame
−
resistant material
(leather, heavy cotton, wool). Body protection includes oil-free cloth-
ing such as leather gloves, heavy shirt, cuff less trousers, high shoes,
and a cap.
•
Remove any combustibles, such as butane lighter or matches, from
your person before doing any welding.
•
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
•
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for
hot work and have a fire watcher and extinguisher nearby.
•
Read and understand the Safety Data Sheets (SDSs) and the manufac-
turer’s instructions for adhesives, coatings, cleaners, consumables,
coolants, degreasers, fluxes, and metals.

Additional Installation, Operation and Maintenance Hazard Symbols
READ USER MANUAL
Read and follow all Power Source labels and
User Manual carefully before installing, op-
erating, or servicing the Power Source.
•
Read the safety information at the begin-
ning of the manual and in each section.
•
Perform installation, maintenance, and ser-
vice according to the User Manual, industry
standards, and national, state, and local
codes.
IMPROPER INSTALLATION can cause fire
Improper equipment installation can cause
fire.
•
Do not install or place Power Source on,
over, or near combustible surfaces.
•
Do not install Power Source near flammables.
•
Do not overload building wiring; be sure Input Power Supply system
is properly sized, rated, and protected for weld system.
ARC WELDING can cause interference
Arc welding produces electromagnetic en-
ergy that can interfere with sensitive elec-
tronic equipment.
•
Electronic equipment that can be affected are computers, telecom-
munication equipment, and computer-driven equipment such as ro-
bots.
•
Be sure all equipment in the welding area is electromagnetically com-
patible.
•
To reduce possible interference, keep weld cables as short as possi-
ble, close together, and down low, such as on the floor.
•
Locate welding operation 100 meters from any sensitive electronic
equipment.
•
Be sure this Power Source is installed and grounded according to
this manual.
•
If interference still occurs, the user must take extra measures such
as moving the Power Source, using shielded cables, using line filters,
or shielding the work area.
COMPRESSED AIR can injure or kill.
Whipping air hoses can injure.
A concentrated stream of air at high pres-
sure and high speed that can cause serious
injury you or people around you.
•
Do not direct air stream toward self or others.
•
Wear protective equipment such as safety
glasses, hearing protection, leather gloves,
heavy shirt / trousers, steel toe boots, and a
cap when working on compressed air system.
•
Release air pressure from air system / air tools before servicing, add-
ing or changing attachments.
•
Turn off and lockout / Tagout air compressor, release air pressure from
system and be sure air pressure cannot be accidentally reapplied be-
fore working on compressed air system.
•
Relieve air pressure before disconnecting or connecting air lines.
•
Check compressed air system components and all connections and
hoses for damage, leaks and wear before operating unit.
•
Use soapy water to search for leaks; never use bare hands. Do not use
equipment if leaks are found.
