Plasma Cutter
ATTENTION!
The following user manual should be read prior installing and starting the device. Manual
OSH manual should be known to every operator and employee responsible for equipment maintenance.
Attention!
Commissioning and normal operation are possible only after reading the carefully reading following manual.
Cutting with plasma arc requires fulfilment of conditions resulting from fire regulations. The operator of se
-
mi-automatic cutter should be supplied with protective clothing and equipment in accordance with current
regulations. It is necessary to use a set of personal protective equipment (PPE) in accordance with according
to provisions of the Council Directive 89/686/EEC. Personal protective equipment (PPE) includes: welding
mask, welding glasses, welding gloves, welding apron, leather shoes, hearing protectors. Despite the high
technical standard of the device, the personnel should represent considerable discipline in approach to
health and safety requirements to protect against harmful and health hazardous factors developed from
cutting technology.
OPERATING CONDITIONS
This device can operate under severe conditions. It is however important to apply simple preventive measu
-
res to ensure long and reliable work:
•
do not place or use this device on an inclined surface (of more than 15°),
•
do not use the device for pipe defrosting,
•
the device needs to be located in a place with free clean air circulation free clean air circulation (to and
•
from the fan without obstacles). When connected to electrical network
•
the device must not be covered e.g. with a tilt,
•
minimize the amount of dirt and dust that can get into the device,
•
device has an IP23S protection rating of housing, keep it dry and not locate
•
on wet surfaces or in a puddle.
•
do not use the device for cutting tanks previously used for flammable substances storing, as there is a
•
risk of explosion,
•
device is designed to work in industrial conditions and is marked as class A according to PN-EN 60974-10
GASES AND FUMES
Plasma cutting techniques produce harmful gases and fumes containing ozone and hydrogen as well as oxi
-
des or metal particles. Therefore, the cutting work station should be fitted with very good ventilation (dust
and smoke extraction or airy location) Metal surfaces intended for cutting should be free from chemical
contamination, especially degreasers (solvents) that decompose during welding process and produce toxic
gases. Cutting of galvanized, cadmium-coated or chromium-plated parts is permitted only when a suction
and filtering device is fitted, and with introduction of fresh air to the cutting work station.
RADIATION
Ultraviolet emission radiated when cutting is harmful to eyesight and skin. Therefore a welding mask with
protective filters is required.
