1.0 Safety Precautions
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or severe burns.
The electrode and work circuit is electrically live whenever the output
is on. The input power circuit and machine internal circuits are also
live when power is on.
Do not touch live electrical parts.
Wear dry, sound insulating gloves and body protection.
Insulate yourself from work and ground using dry insulating mats
or covers big enough to prevent any physical contact with the work
ground.
Additional safety precautions are required when any of the following
electrically hazardous conditions are present: in damp locations
or while wearing wet clothing; on metal structures such as oors,
gratings, or scaffolds; when in cramped positions such as sitting,
kneeling, or lying; or when there is a high risk of unavoidable or
accidental contact with the work piece or ground.
Disconnect input power before installing or servicing this equipment.
Lockout/tagout input power according to Safety Standards.
Properly install and ground this equipment according to national and
local standards.
Always verify the supply ground - check and ensure that input power
cable ground wire is properly connected to ground terminal in the
receptacle outlet.
When making input connections, attach proper grounding conductor
rst - double-check connections.
Frequently inspect input power cable for damage or bare wiring replace cable immediately if damaged - bare wiring can kill.
Turn off all equipment when not in use.
Do not use worn, damaged, under sized, or poorly spliced cables.
Do not drape cables over your body.
If earth grounding of the work piece is required, ground it directly
with a separate cable.
Do not touch electrode if you are in contact with the work, ground, or
another electrode from a different machine.
Use only well-maintained equipment. Repair or replace damaged
parts at once. Maintain unit according to manual.
Wear a safety harness if working above oor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to work piece or
worktable as near the weld as practical.
Insulate work clamp when not connected to work piece to prevent
contact with any metal object.
Welding produces fumes and gases. Breathing these fumes and
gases can be hazardous to your health.
FUMES AND GASES can be hazardous.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use local forced ventilation at the
arc to remove welding fumes and gases.
If ventilation is poor, wear an approved respirator.
Read and understand the Material Safety Data Sheets (MSDS’s) and
the manufacturer’s instructions for metals, consumable, coatings,
cleaners, and de-greasers.
Work in a conned space only if it is well ventilated, or while wearing
an air-supplied respirator. Always have a trained watch person
nearby. Welding fumes and gases can displace air and lower the
oxygen level causing injury or death. Be sure the breathing air is
safe.
Do not weld in locations near de-greasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapours to
form highly toxic and irritating gases.
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.
ARC RAYS 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 y off from the weld.
Wear an approved welding helmet tted with a proper shade of lter
lense to protect your face and eyes when welding or watching
Wear approved safety glasses with side shields under your helmet.
Use protective screens or barriers to protect others from ash, glare
and sparks; warn others not to watch the arc.
Wear protective clothing made from durable, ame resistant material
(leather, heavy cotton, or wool) and foot protection. Welding on
closed containers, such as tanks, drums, or pipes, can cause them
to blow up. Sparks can y off from the welding arc. The ying sparks,
hot work piece, and hot equipment can cause res and burns.
Accidental contact of electrode to metal objects can cause sparks,
explosion, overheating, or re. Check and be sure the area is safe
before doing any welding.
WELDING can cause re or explosion.
Remove all ammables within 10m of the welding arc. If this is not
possible, tightly cover them with approved covers.
Do not weld where ying sparks can strike ammable material.
Protect yourself and others from ying sparks and hot metal.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
SAFETY
5
Watch for re, and keep a re extinguisher nearby. Be aware that
welding on a ceiling, oor, bulkhead, or partition can cause re on
the hidden side.
Do not weld on closed containers such as tanks, drums, or pipes,
unless they are properly prepared according to local regulations
Connect work cable to the work as close to the welding area as
practical to prevent welding current from travelling along, possibly
unknown paths and causing electric shock, sparks, and re hazards.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cufess trousers, high shoes, and a cap. Remove any
combustibles, such as a butane lighter or matches, from your person
before doing any welding.
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding cause sparks and
ying metal. As welds cool they can throw off slag. Wear approved
safety glasses with side shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use. Always ventilate
conned spaces or use approved air-supplied respirator.
HOT PARTS can cause severe burns.
Do not touch hot parts with bare hands.
Allow cooling period before working on gun or torch.
To handle hot parts, use proper tools and/or wear heavy, insulated
welding gloves and clothing to prevent burns.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before going near arc welding,
gouging, or spot welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
Shielding gas cylinders contain gas under high pressure.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat, mechanical
shocks, physical damage, slag, open ames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping. Keep cylinders
away from any welding or other electrical circuits. Never drape a
welding torch over a gas cylinder. Never allow a welding electrode to
touch any cylinder. Never weld on a pressurized cylinder - explosion
will result. Use only correct shielding gas cylinders, regulators,
hoses, and ttings designed for the specic application; maintain
them and associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Use the right equipment, correct procedures, and sufcient number
of persons to lift and move cylinders.
Read and follow instructions on compressed gas cylinders,
associated equipment, and Compressed Gas Association (CGA)
recommendations.
2.0 Product Description
This welding machine is manufactured using
advanced inverter technology. The input voltage is rectied to
DC and then inverted to high frequency AC voltage. before being
converted back to DC for the output .This allows the use of a much
smaller transformer and so allowing weight saving and improved
power efciency.
