SECTION 1- SAFETY CAUTIONS & SYMBOLS
CAUTION: READ USER MANUAL
Indicates any section that the user must read the manual to fully understand the machine’s characteristics to avoid
any hazardous situation.
ELECTRIC SHOCK
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.
Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical
contact with the work or ground.
Do not remove any machine covers while the machine is powered.
WELDING WORKPLACE
Be mindful of working in cramped positions, scaffolds, or any location where you can fall and become injured.
Wear a safety harness if working above floor level.
Do not work in wet areas, or while wearing wet clothing.
WELDED PARTS
Immediately after welding, all welded parts will be a very high temperature which will cause burns to any exposed
skin that makes contact.
Do not touch parts after welding. Allow for cooling period before picking up.
Allow cooling period before working on equipment.
To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent
burns.

5
WELDING FUMES
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
Keep your head out of the fumes stream while welding. Do not breathe the fumes.
If inside, ventilate the area and/or use local forced ventilation at the welding point to remove welding fumes
and gases.
If ventilation is poor, wear an approved air-supplied respirator.
Read and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s instructions for metals,
consumables, coatings, cleaners, and degreasers.
Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Welding fumes
and gases can displace air and lower the oxygen level causing injury or death. Always have a trained
watchperson nearby.
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.
WELDING RAYS
Rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes
and skin.
Wear an approved welding helmet fitted with a proper shade of filter lenses to protect your face and eyes from
welding rays.
Use protective screens or barriers to protect others from flash, glare and sparks; warn others not to watch the
arc.
Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or wool) and to
cover any exposed skin, arms, neck area.
WELDING FIRES
Welding creates heat and can lead to fires, as well certain welding forms create sparks which could also ignite
surrounding items and create a fire. The flying sparks, hot workpiece, and hot equipment can cause fires and burns.
Remove all flammables within 35 ft. (10.7 m) of the welding arc. If this is not possible, 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. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden
side.
Watch for fire, and keep a fire extinguisher nearby.

6
GASES
Dangerous gases can be produced during welding, breathing these gases in can be hazardous to your health.
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use approved air-supplied respirator.
Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react
with vapors to form highly toxic and irritating gases.
EMF- ELECTRIC MAGNETIC FIELDS
During welding, electric magnetic fields are created and can produce malfunctions in electrical components within the
area.
EMF created by welders may affect wearers of Pacemakers and other Implanted Medical Devices should keep
away.
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.
EXCESSIVE NOISE
Be mindful if your working area creates excessive noise.
Wear approved ear protection if noise level is high.
Any workers close by the area will also be effected by the noise and may also require hearing protection.
GAS CYLINDER/LINE DAMAGE
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are
normally part of the welding process, be sure to treat them carefully.
Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames,
sparks, and arcs.
Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or
tipping.
Protect all gas lines from sparks, slag and open flames.
Open the cylinder valve slowly. Then slowly open regulator valve to avoid damage to the regulator.

7
ESD- ELECTRIC STATIC DISCHARGE
An electric static charge can be created during welding and discharged immediately after into any items touched by
the welder after welding.
Put on grounded wrist strap BEFORE handling boards or parts.
Use proper static-proof bags and boxes to store, move, or ship PC boards.
MOVING PARTS
A number of moving parts may be in typical welding machines such as rollers and fans.
Keep hands away from moving parts such as fans.
Keep all doors, panels, covers, and guards closed and securely in place.
Keep away from moving parts.
Keep away from pinch points such as drive rolls.
Secure any loose clothing and hair and keep away from moving parts.

SECTION 4- MAINTENANCE & BASIC TROUBLESHOOTING
MAINTENANCE
Please disconnect power to machine before performing maintenance.
Check periodically whether cable connection is in good condition (esp. plugs). Tighten any loose connections. If
there is oxidization, remove it with sandpaper and then reconnect.
Clean the dust inside the machine periodically with dry and clean compressed air. If welding environment has
heavy smoke and pollution, machine should be cleaned daily. The pressure of the compressed air should be at a
low pressure in order to avoid the small parts inside the machine being damaged.
Avoid water and vapor entering the machine. If this occurs, dry machine internals and check the insulation of
the equipment (including that between the connections and that between the connection and the enclosure).
Only when there is no moisture present, can the machine be used.
Check all cables periodically, to be sure they are in good condition with no worn spots or cracks in outer
insulation. If there is any dilapidation, rewrap it or replace all damaged cables.
Put the machine into clean packing and in a dry location if it is not to be used for an extended period of time.
If machine is in an environment that is in or near chemicals, cover machine when not in use.
