Safety precautions
The equipment is designed for the qualified personnel who have passed professional
training. The operator shall have sufficient professional knowledge of welding, cutting
and circuit, and have obtained the qualification certificate of welder. Only operate the
machine after reading and fully understanding all the safety precautions and warnings
in the manual and of welding operations. Basic safety precautions should always be
followed when using tools, to reduce the risk of personal injury and damage to
equipment. The device is simple and reliable in selecting and performing all of its
functions. The operator must strictly follow the safety precautions below and execute
them as required. Improper use and maintenance will reduce the safety performance
of the machine.
1. The operator must have passed the systematic training and assessment of local
welder's relevant learning institution and obtained the qualified certificate before
operating the equipment.
2. The wire and cable connection of the equipment, as well as the installation, must
be operated by qualified professional and technical personnel.
3. The welding and cutting protective equipment used by the operator must be
provided by the manufacturer or distributor approved by the national safety
supervision department of the local country.
4. Welding and cutting is dangerous work, which may cause harm to you or others,
so sufficient protection should be done during welding and cutting. Please strictly
abide by the relevant safety precautions of the job operation. For more details, please
refer to the relevant safety guidelines for the operators to comply with the
manufacturer's regulations on accident prevention.
5. Please make sure that the welding/cutting machine is reliably grounded when
working. Please contact the professional electrician to solve the problems in time if
there is any doubt that the socket is not grounded or the grounding is not reliable.
6. Before welding/cutting , check whether the insulation layer of all wires and cables
of the machine is damaged or they are wrongly connected timely and fix them in a
timely manner if they are.
7. The faulty machine must be repaired by professional technicians. The machine
must be disconnected from the electricity supply before repair and maintenance.

Warnings
Welding and cutting is a special type of work, with a certain degree of danger.
Professional training, correct operation and necessary protective measures can
effectively avoid and reduce the damage and loss caused by machine accidents.
Personal and others’ safety protection
When welding and cutting equipment is working, it will generate
noise, strong light and high temperature sparks, which will cause
harm to human hearing, eyes and skin. Correct protective measures
and proper operation training are necessary to prevent injury
accidents.
1
Aprotective helmet with a shading filter must be worn to protect the face and
eyes during welding and cutting operations or when watching welding/cutting
operations.
2
Wear a helmet with the correct filter and cover plate to protect the eyes, face,
neck and ears from arcing sparks and bright light during welding operation or
observation. Warn bystanders not to look at the arc and not to expose their
skin in the area of strong light arc or high temperature spark
3
Wear flame retardant gloves, flame retardant welding/cutting overalls, flame
retardant shoes, and welding/cutting helmets or protective caps to protect
against arcing bright lights, high temperature sparks or hot metal particles. A
flame retardant apron is also available to protect against thermal radiation
and high temperature sparks.
4
Hot sparks or metal can get into rolled-up sleeves, trouser legs or pockets.
Before welding/cutting, sleeves and collars should be buttoned, and clothes
with front pockets should not be worn.
