• Turn off all equipment when not in use. • Do not use frayed, damaged, undersized, or
poorly spliced cables. • Do not place cables across your body.
• If workpiece grounding is required, ground it directly with a separate cable; do not use
work clamp or work cable.• Do not touch electrode if it is in contact with work, ground, or
another electrode from a different machine.• Use only equipment that is well maintained and
in good repair. Repair or replace damaged parts at once. Maintain the unit in accordance
with the manual.• Use a safety harness if working on higher levels or at risk of falling.• Keep
all protective panels and covers on the machine in place.• Fasten the work cable with a
good metal-to-metal contact with the workpiece or worktable as close as possible to the
weld.
SIGNIFICANT DC VOLTAGE exists after removal of input power to the
inverters. • Shut down the inverter, disconnect input power, and discharge
input capacitors before touching any part with machine elements.
FUMES AND GASES can be dangerous to your health. Welding produces
fumes and gases. Breathing these fumes and gases can be dangerous to
your health.
• Keep your head out of the fumes. Do not breathe welding fumes.• If indoors,
ventilate area and/or use gas exhaust to remove welding fumes and gases.•
If ventilation is poor, use supplied respirator • Read Material Safety Data Sheets (MSDS)
and manufacturer's instructions for metals, consumables, coatings, cleaners, and
degreasers. • Work in a confined space only if it is well ventilated or if you wear a respirator
with air supply. Always have a trained spotter nearby. Welding fumes and
gases can displace air and lower the oxygen level and cause injury or death.
Make sure breathing air is safe.• Do not weld near degreasing operations,
cleaning or spraying. Heat and rays from the welding arc can react with vapors
to form highly toxic and irritating gases.
• Do not weld coated metals, such as galvanized steel, lead or cadmium, unless the coating
is removed from the welding area, the area is well ventilated and, if necessary, with a
supplied air respirator. Coatings and any metal containing these elements can give off toxic
fumes if they are welded.
Rays from the welding arc can burn eyes and skin. Arc rays from the welding
process produce intense visible and invisible (ultraviolet and infrared) rays that
can burn eyes and skin. Sparks fly from the weld.• Wear a welding helmet
equipped with a suitable shade filter to protect your face and eyes when
welding or watching (see ANSI Z49.1 and Z87.1 listed in the Safety Standards).• Wear
approved safety glasses with side shields under your hard hat. • Use protective shields or
barriers to protect others from flash and glare; Warn others not to look directly at the
welding arc. • Wear protective clothing made of durable, flame-resistant material (leather
and wool) and foot protection.
Welding can cause fires or explosions. Welding on closed containers, such as
tanks, drums, or pipes, can cause them to burst. Sparks can fly from the
welding arc. Emitted sparks, hot workpiece, and hot equipment can cause fires
