INTIG 401 PULSE
DC Pulse Argon Welding Machine
1
Electric shock
: The welding circuits are not insulated when welding. If you touch
the two output electrodes of the machine with your bare skin at the same time, it
will lead to electric shock, sometimes even fatal dangers. Users need to follow the
items below to avoid electric shocks:
If possible, lay some insulating materials, which are dry and large enough, in your
working field. Otherwise, use the automatic or semiautomatic welding machine, DC
welding machine as possible as you can.
Components in the automatic and semiautomatic welding machine such as the
welding wire reel, feed wheel, contact tip and welding head are all electriferous.
Always be sure the machine has been connected perfectly to the work piece with
the work cables and should be as close as possible to the working area.
The work piece should be grounded perfectly.
Make sure that the insulating material of the electrode holder, the grounding clamp,
the welding cable and the welding head are not affected by damp, mildewed or
spoilt, and be replaced momentarily.
Never dip the electrode in water for cooling.
Never touch electriferous parts of two welding machines at the same time, because
this voltage is supposed to be two times of welding voltage while the grounding
mode is not clear.
While working high above the ground or other places having the risk of falling,
please be sure to wear safety belt to avoid losing balance caused by electric shock.
2
Arc
: Use an arc welding mask to protect your eyes and skin from sparks and the
rays of the arc, pay special attention to the filter glass, which must be conformable
to the national standard.
Use clothing made from durable flame-resistant material or sailcloth to protect your
skin from hurting by the arc rays.
Remind other nearby personnel before working lest arc rays hurt them by accident.
3
Fumes and Gases
: Welding may produce fumes and gases hazardous to health.
Avoid breathing these fumes and gases. While working in limited room, use enough
ventilation and/or exhaust to keep fumes and gases away from the breathing zone,
or use the respirator. Do not weld at the same time when using of degreasing,
cleaning or spraying operations. The heat and rays of the arc can react with these
gases to form phosgene, a highly toxic gas,.
Some protective gases used in welding might displace the oxygen in the air, and
can lead to hurt or even death.
Read and understand the manufacturer’s instructions for this equipment, and
validate the health certification of consumptive materials, make sure they are
asepsis and innocuity.
4
Spatter
: Spatter can cause fire or explosion.
Remove fire hazards from the welding area. Remember that spatter from welding
can easily go through small cracks and touch fire hazards. Keep the safety of all
kinds of lines going though welding area, including hydraulic lines in the wild.
Where compressed gases are to be used in the field, special precautions should be
used to prevent explosion.
When not welding, make certain that no electriferous part is touching the work piece
or the work stage. Accidental contact can create a fire hazard.
Do not weld containers or lines, which are not proved to be innocuity.
It is very dangerous to heat, cut or weld tanks or containers at entry holes. Does not
start work until the proper steps have been taken to insure that there are no
flammable or toxic gases there.
Spatter might cause burn. Wear leather gloves, heavy shirt, cuffless trousers, high
shoes and a cap over your hair to prevent from burning by spatter. Wear the ear
shield when performing sideways or face up welding. Always wear safety glasses
with side shields when being in a welding area.
The welding cables should be as close to the welding area as possible, and the
short, the better. Avoid welding cables going through the building framework, lifting
chains, AC or DC cables of other welding machines and appliances. The welding
current is strong enough to damage them while having short circuit with them.
5
Cylinder
: Damage of it might cause explosion.
Make sure that the gas in the storage cylinder is qualified for welding, and the
decompression flow-meter, the adapter and the pipe are all in good condition.
Make sure that the installation of cylinder is by the wall and bundled tightly by a
chain.
Be sure to put the cylinder in the working space with no crash or shake, and far from
welding area.
It is forbidden to touch cylinder with the welding clamp or the work cables.
