Arc welding and cutting can be dangerous to user and surroundings in case of improper use. Therefore, the
equipment must be used only under the strict observance of all relevant safety instructions. In particular,
your attention is drawn to the following:
Installation and use
• The welding equipment must be installed and used
by authorized personnel according to EN/IEC60974-9.
Migatronic takes no responsibility for unintended
use or use beyond the specifications of the machine/
cables.
Meeting requirements for electricity values
• All Migatronic welding machines are manufactured
according to the technical safety regulations valid in
the EU.
The welding machines are designed according to
the Low-voltage directive of the Danish Safety
Technology Authority and meet the requirements of
DS/EN/IEC 60974-3.
The welding machines comply with maximum
values according to DN/EN/IEC 60974-3 for manually
operated torches.
Peak voltage: 15kV
Electric load: 8uC
Average energy (period: 1 second): 4J
Electricity
• The welding/cutting equipment must be installed
according to regulations. The machine must be
connected to earth through the mains cable.
• Make sure that the welding equipment is regularly
inspected.
• In case of damaged cables or insulation, work must
be stopped immediately in order to carry out repairs.
• Inspection, repair and maintenance of the
equipment must be carried out by a properly trained
and qualified person.
• Avoid all contact with live components in the cutting
torch, earth clamp or electrodes if you have bare
hands.
• Keep your clothes dry and never use defective or wet
welding gloves.
• Make sure that you are properly and safely earthed
(e.g. use shoes with rubber sole).
• Use a safe and stable working position (avoid risk of
falling).
• Observe the rules for “Welding under special
working conditions”.
• Disconnect the machine prior to disassembling the
torch in case of change of electrode or other service.
• Use specified welding/cutting torches and spare
parts only (see spare parts list).
Shocks from high frequency ignition (TIG/PLASMA)
• If your TIG/Plasma welding machine is installed
correctly and you maintain and use it according
to instructions, the welding machine will not
jeopardize the safety of you and other persons.
Improper use of the welding machine may cause
shocks from a high frequency (HF) ignition. Getting
shocks from a high frequency ignition on a welding
machine is not dangerous but you are advised to
consult a doctor if you feel unwell.
Light and heat emissions
• Protect the eyes as even short-term exposure may
cause permanent eyesight damage. Use welding
helmet with prescribed radiation protection glass.
• Protect the body against the light from the arc as
the skin may be damaged by welding radiation. Use
protective clothes, covering all parts of the body.
• Shield the place of work, if possible, and warn other
persons in the area against the light from the arc.
Smoke and gases
• Inhalation of smoke and gases emitted during
welding/cutting is very damaging to health. Ensure
proper ventilation and extraction.
Fire hazard
• Radiation and sparks from the arc represent a fire
hazard. Keep combustible materials away from the
place of welding/cutting.
• Working clothes should be protected against sparks
and spatter from the arc (use a welding apron and
beware of open pockets).
• The special regulations for rooms with danger of fire
and explosion must be observed.
Noise
• The arc generates acoustic and electromagnetic
noise, the level of which depends on the welding/
cutting operation, which is why the use of hearing
protection will often be necessary.
• Welders using pacemakers or hearing aids should
minimize electromagnetic interference by using the
shortest possible plus and minus cables, arranged
side by side at floor level.
Dangerous areas
• Avoid putting your fingers into the rotating gear
wheels in the wire feed unit.
• Take the necessary precautions when welding/
cutting is carried out in confined spaces or at heights
where there is a risk of falling.
Positioning of the machine
• Place the welding/cutting machine in such a way
that the risk of tipping over is avoided.
• The special regulations for rooms with danger of fire
and explosion must be observed.
Lifting the welding/cutting machine
• CAUTION SHOULD BE EXERCISED when lifting the
welding/cutting machine. Use a lifting device if
possible in order to prevent back injuries. Read
lifting instructions in the instruction manual.
Use of the machine for other purposes than it is
designed for (e.g. thawing frozen water pipes) is not
advisable and will be on user’s own responsibility.
